X should -# be either GC_malloc or GC_malloc_uncollectable, or -# GC_debug_malloc_replacement. (The latter invokes GC_debug_malloc -# with dummy source location information, but still results in -# properly remembered call stacks on Linux/X86 and Solaris/SPARC.) -# The former is occasionally useful for working around leaks in code -# you don't want to (or can't) look at.

If you build with DBG_HDRS_ALL, -# you should only use GC_debug_malloc_replacement as a malloc -# replacement. -# -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X. -# The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement, -# together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to -# generate leak reports with call stacks for both malloc and realloc. -# -DIGNORE_FREE turns calls to free into a noop. Only useful with -# -DREDIRECT_MALLOC. -# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls. -# Reduces code size slightly at the expense of debuggability. -# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of -# order by specifying a nonstandard finalization mark procedure (see -# finalize.c). Objects reachable from finalizable objects will be marked -# in a sepearte postpass, and hence their memory won't be reclaimed. -# Not recommended unless you are implementing a language that specifies -# these semantics. Since 5.0, determines only only the initial value -# of GC_java_finalization variable. -# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response -# to explicit GC_invoke_finalizers() calls. -# In 5.0 this became runtime adjustable, and this only determines the -# initial value of GC_finalize_on_demand. -# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable. -# This is useful if either the vendor malloc implementation is poor, -# or if REDIRECT_MALLOC is used. -# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly -# sets the heap block size. Each heap block is devoted to a single size and -# kind of object. For the incremental collector it makes sense to match -# the most likely page size. Otherwise large values result in more -# fragmentation, but generally better performance for large heaps. -# -DUSE_MMAP use MMAP instead of sbrk to get new memory. -# Works for Solaris and Irix. -# -DUSE_MUNMAP causes memory to be returned to the OS under the right -# circumstances. This currently disables VM-based incremental collection. -# This is currently experimental, and works only under some Unix, -# Linux and Windows versions. -# -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than -# GC_scratch_alloc() to get stack memory. -# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever -# the garbage collector detects a value that looks almost, but not quite, -# like a pointer, print both the address containing the value, and the -# value of the near-bogus-pointer. Can be used to identifiy regions of -# memory that are likely to contribute misidentified pointers. -# -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers -# for objects allocated with the debugging allocator. If all objects -# through GC_MALLOC with GC_DEBUG defined, this allows the client -# to determine how particular or randomly chosen objects are reachable -# for debugging/profiling purposes. The gc_backptr.h interface is -# implemented only if this is defined. -# -DGC_ASSERTIONS Enable some internal GC assertion checking. Currently -# this facility is only used in a few places. It is intended primarily -# for debugging of the garbage collector itself, but could also -# -DDBG_HDRS_ALL Make sure that all objects have debug headers. Increases -# the reliability (from 99.9999% to 100%) of some of the debugging -# code (especially KEEP_BACK_PTRS). Makes -DSHORT_DBG_HDRS possible. -# Assumes that all client allocation is done through debugging -# allocators. -# -DSHORT_DBG_HDRS Assume that all objects have debug headers. Shorten -# the headers to minimize object size, at the expense of checking for -# writes past the end of an object. This is intended for environments -# in which most client code is written in a "safe" language, such as -# Scheme or Java. Assumes that all client allocation is done using -# the GC_debug_ functions, or through the macros that expand to these, -# or by redirecting malloc to GC_debug_malloc_replacement. -# (Also eliminates the field for the requested object size.) -# occasionally be useful for debugging of client code. Slows down the -# collector somewhat, but not drastically. -# -DSAVE_CALL_COUNT=<n> Set the number of call frames saved with objects -# allocated through the debugging interface. Affects the amount of -# information generated in leak reports. Only matters on platforms -# on which we can quickly generate call stacks, currently Linux/(X86 & SPARC) -# and Solaris/SPARC and platforms that provide execinfo.h. -# Default is zero. On X86, client -# code should NOT be compiled with -fomit-frame-pointer. -# -DSAVE_CALL_NARGS=<n> Set the number of functions arguments to be -# saved with each call frame. Default is zero. Ignored if we -# don't know how to retrieve arguments on the platform. -# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly -# altered stubborn objects, at substantial performance cost. -# Use only for debugging of the incremental collector. -# -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems -# that include a pointer to a type descriptor in each allocated object). -# Building this way requires an ANSI C compiler. -# -DUSE_I686_PREFETCH causes the collector to issue Pentium III style -# prefetch instructions. No effect except on X86 Linux platforms. -# Assumes a very recent gcc-compatible compiler and assembler. -# (Gas prefetcht0 support was added around May 1999.) -# Empirically the code appears to still run correctly on Pentium II -# processors, though with no performance benefit. May not run on other -# X86 processors? In some cases this improves performance by -# 15% or so. -# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style -# prefetch instructions. Same restrictions as USE_I686_PREFETCH. -# Minimally tested. Didn't appear to be an obvious win on a K6-2/500. -# -DGC_USE_LD_WRAP in combination with the old flags listed in README.linux -# causes the collector some system and pthread calls in a more transparent -# fashion than the usual macro-based approach. Requires GNU ld, and -# currently probably works only with Linux. -# -DTHREAD_LOCAL_ALLOC defines GC_local_malloc(), GC_local_malloc_atomic() -# and GC_local_gcj_malloc(). Needed for gc_gcj.h interface. These allocate -# in a way that usually does not involve acquisition of a global lock. -# Currently requires -DGC_LINUX_THREADS, but should be easy to port to -# other pthreads environments. Recommended for multiprocessors. -# -DPARALLEL_MARK allows the marker to run in multiple threads. Recommended -# for multiprocessors. Currently requires Linux on X86 or IA64, though -# support for other Posix platforms should be fairly easy to add, -# if the thread implementation is otherwise supported. -# -DNO_GETENV prevents the collector from looking at environment variables. -# These may otherwise alter its configuration, or turn off GC altogether. -# I don't know of a reason to disable this, except possibly if the -# resulting process runs as a privileged user? -# -DUSE_GLOBAL_ALLOC. Win32 only. Use GlobalAlloc instead of -# VirtualAlloc to allocate the heap. May be needed to work around -# a Windows NT/2000 issue. Incompatible with USE_MUNMAP. -# See README.win32 for details. -# -DMAKE_BACK_GRAPH. Enable GC_PRINT_BACK_HEIGHT environment variable. -# See README.environment for details. Experimental. Limited platform -# support. Implies DBG_HDRS_ALL. All allocation should be done using -# the debug interface. -# -DSTUBBORN_ALLOC allows allocation of "hard to change" objects, and thus -# makes incremental collection easier. Was enabled by default until 6.0. -# Rarely used, to my knowledge. -# -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed -# from a multithreaded parent.

See README.irix. -# -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads. -# Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L.

(See gc_priv.h for consequences.) -# Alternatively, GC_all_interior_pointers can be set at process -# initialization time. -# -DSMALL_CONFIG tries to tune the collector for small heap sizes, -# usually causing it to use less space in such situations. -# Incremental collection no longer works in this case. -# -DLARGE_CONFIG tunes the collector for unusually large heaps. -# Necessary for heaps larger than about 500 MB on most machines. -# Recommended for heaps larger than about 64 MB. -# -DDONT_ADD_BYTE_AT_END is meaningful only with -DALL_INTERIOR_POINTERS or -# GC_all_interior_pointers = 1. Normally -DALL_INTERIOR_POINTERS -# causes all objects to be padded so that pointers just past the end of -# an object can be recognized. This can be expensive. (The padding -# is normally more than one byte due to alignment constraints.) -# -DDONT_ADD_BYTE_AT_END disables the padding. -# -DNO_SIGNALS does not disable signals during critical parts of -# the GC process. This is no less correct than many malloc -# implementations, and it sometimes has a significant performance -# impact. However, it is dangerous for many not-quite-ANSI C -# programs that call things like printf in asynchronous signal handlers. -# This is on by default. Turning it off has not been extensively tested with -# compilers that reorder stores. It should have been. -# -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not -# have execute permission, i.e. it may be impossible to execute -# code from the heap. Currently this only affects the incremental -# collector on UNIX machines. It may greatly improve its performance, -# since this may avoid some expensive cache synchronization. -# -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support -# the new syntax "operator new[]" for allocating and deleting arrays. -# See gc_cpp.h for details. No effect on the C part of the collector. -# This is defined implicitly in a few environments. Must also be defined -# by clients that use gc_cpp.h. -# -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be -# defined as aliases for X, GC_realloc, and GC_free, respectively. -# Calloc and strdup are redefined in terms of the new malloc. X should -# be either GC_malloc or GC_malloc_uncollectable, or -# GC_debug_malloc_replacement. (The latter invokes GC_debug_malloc -# with dummy source location information, but still results in -# properly remembered call stacks on Linux/X86 and Solaris/SPARC.) -# The former is occasionally useful for working around leaks in code -# you don't want to (or can't) look at. It may not work for -# existing code, but it often does. Neither works on all platforms, -# since some ports use malloc or calloc to obtain system memory. -# (Probably works for UNIX, and win32.) If you build with DBG_HDRS_ALL, -# you should only use GC_debug_malloc_replacement as a malloc -# replacement. -# -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X. -# The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement, -# together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to -# generate leak reports with call stacks for both malloc and realloc. -# -DIGNORE_FREE turns calls to free into a noop. Only useful with -# -DREDIRECT_MALLOC. -# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls. -# Reduces code size slightly at the expense of debuggability. -# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of -# order by specifying a nonstandard finalization mark procedure (see -# finalize.c). Objects reachable from finalizable objects will be marked -# in a sepearte postpass, and hence their memory won't be reclaimed. -# Not recommended unless you are implementing a language that specifies -# these semantics. Since 5.0, determines only only the initial value -# of GC_java_finalization variable. -# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response -# to explicit GC_invoke_finalizers() calls. -# In 5.0 this became runtime adjustable, and this only determines the -# initial value of GC_finalize_on_demand. -# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable. -# This is useful if either the vendor malloc implementation is poor, -# or if REDIRECT_MALLOC is used. -# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly -# sets the heap block size. Each heap block is devoted to a single size and -# kind of object. For the incremental collector it makes sense to match -# the most likely page size. Otherwise large values result in more -# fragmentation, but generally better performance for large heaps. -# -DUSE_MMAP use MMAP instead of sbrk to get new memory. -# Works for Solaris and Irix. -# -DUSE_MUNMAP causes memory to be returned to the OS under the right -# circumstances. This currently disables VM-based incremental collection. -# This is currently experimental, and works only under some Unix, -# Linux and Windows versions. -# -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than -# GC_scratch_alloc() to get stack memory. -# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever -# the garbage collector detects a value that looks almost, but not quite, -# like a pointer, print both the address containing the value, and the -# value of the near-bogus-pointer. Can be used to identifiy regions of -# memory that are likely to contribute misidentified pointers. -# -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers -# for objects allocated with the debugging allocator. If all objects -# through GC_MALLOC with GC_DEBUG defined, this allows the client -# to determine how particular or randomly chosen objects are reachable -# for debugging/profiling purposes. The gc_backptr.h interface is -# implemented only if this is defined. -# -DGC_ASSERTIONS Enable some internal GC assertion checking. Currently -# this facility is only used in a few places. It is intended primarily -# for debugging of the garbage collector itself, but could also -# -DDBG_HDRS_ALL Make sure that all objects have debug headers. Increases -# the reliability (from 99.9999% to 100%) of some of the debugging -# code (especially KEEP_BACK_PTRS). Makes -DSHORT_DBG_HDRS possible. -# Assumes that all client allocation is done through debugging -# allocators. -# -DSHORT_DBG_HDRS Assume that all objects have debug headers. Shorten -# the headers to minimize object size, at the expense of checking for -# writes past the end of an object. This is intended for environments -# in which most client code is written in a "safe" language, such as -# Scheme or Java. Assumes that all client allocation is done using -# the GC_debug_ functions, or through the macros that expand to these, -# or by redirecting malloc to GC_debug_malloc_replacement. -# (Also eliminates the field for the requested object size.) -# occasionally be useful for debugging of client code. Slows down the -# collector somewhat, but not drastically. -# -DSAVE_CALL_COUNT=<n> Set the number of call frames saved with objects -# allocated through the debugging interface. Affects the amount of -# information generated in leak reports. Only matters on platforms -# on which we can quickly generate call stacks, currently Linux/(X86 & SPARC) -# and Solaris/SPARC and platforms that provide execinfo.h. -# Default is zero. On X86, client -# code should NOT be compiled with -fomit-frame-pointer. -# -DSAVE_CALL_NARGS=<n> Set the number of functions arguments to be -# saved with each call frame. Default is zero. Ignored if we -# don't know how to retrieve arguments on the platform. -# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly -# altered stubborn objects, at substantial performance cost. -# Use only for debugging of the incremental collector. -# -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems -# that include a pointer to a type descriptor in each allocated object). -# Building this way requires an ANSI C compiler. -# -DUSE_I686_PREFETCH causes the collector to issue Pentium III style -# prefetch instructions. No effect except on X86 Linux platforms. -# Assumes a very recent gcc-compatible compiler and assembler. -# (Gas prefetcht0 support was added around May 1999.) -# Empirically the code appears to still run correctly on Pentium II -# processors, though with no performance benefit. May not run on other -# X86 processors? In some cases this improves performance by -# 15% or so. -# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style -# prefetch instructions. Same restrictions as USE_I686_PREFETCH. -# Minimally tested. Didn't appear to be an obvious win on a K6-2/500. -# -DGC_USE_LD_WRAP in combination with the old flags listed in README.linux -# causes the collector some system and pthread calls in a more transparent -# fashion than the usual macro-based approach. Requires GNU ld, and -# currently probably works only with Linux. -# -DTHREAD_LOCAL_ALLOC defines GC_local_malloc(), GC_local_malloc_atomic() -# and GC_local_gcj_malloc(). Needed for gc_gcj.h interface. These allocate -# in a way that usually does not involve acquisition of a global lock. -# Currently requires -DGC_LINUX_THREADS, but should be easy to port to -# other pthreads environments. Recommended for multiprocessors. -# -DPARALLEL_MARK allows the marker to run in multiple threads. Recommended -# for multiprocessors. Currently requires Linux on X86 or IA64, though -# support for other Posix platforms should be fairly easy to add, -# if the thread implementation is otherwise supported. -# -DNO_GETENV prevents the collector from looking at environment variables. -# These may otherwise alter its configuration, or turn off GC altogether. -# I don't know of a reason to disable this, except possibly if the -# resulting process runs as a privileged user? -# -DUSE_GLOBAL_ALLOC. Win32 only. Use GlobalAlloc instead of -# VirtualAlloc to allocate the heap. May be needed to work around -# a Windows NT/2000 issue. Incompatible with USE_MUNMAP. -# See README.win32 for details. -# -DMAKE_BACK_GRAPH. Enable GC_PRINT_BACK_HEIGHT environment variable. -# See README.environment for details. Experimental. Limited platform -# support. Implies DBG_HDRS_ALL. All allocation should be done using -# the debug interface. -# -DSTUBBORN_ALLOC allows allocation of "hard to change" objects, and thus -# makes incremental collection easier. Was enabled by default until 6.0. -# Rarely used, to my knowledge. -# -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed -# from a multithreaded parent. Currently only supported by linux_threads.c. -# (Similar code should work on Solaris or Irix, but it hasn't been tried.) -# - -CXXFLAGS= $(CFLAGS) -AR= ar -RANLIB= ranlib - - -OBJS= alloc.o reclaim.o allchblk.o misc.o mach_dep.o os_dep.o mark_rts.o headers.o mark.o obj_map.o blacklst.o finalize.o new_hblk.o dbg_mlc.o malloc.o stubborn.o checksums.o solaris_threads.o irix_threads.o linux_threads.o typd_mlc.o ptr_chck.o mallocx.o solaris_pthreads.o gcj_mlc.o specific.o gc_dlopen.o backgraph.o - -CSRCS= reclaim.c allchblk.c misc.c alloc.c mach_dep.c os_dep.c mark_rts.c headers.c mark.c obj_map.c pcr_interface.c blacklst.c finalize.c new_hblk.c real_malloc.c dyn_load.c dbg_mlc.c malloc.c stubborn.c checksums.c solaris_threads.c irix_threads.c linux_threads.c typd_mlc.c ptr_chck.c mallocx.c solaris_pthreads.c gcj_mlc.c specific.c gc_dlopen.c backgraph.c - -CORD_SRCS= cord/cordbscs.c cord/cordxtra.c cord/cordprnt.c cord/de.c cord/cordtest.c include/cord.h include/ec.h include/private/cord_pos.h cord/de_win.c cord/de_win.h cord/de_cmds.h cord/de_win.ICO cord/de_win.RC - -CORD_OBJS= cord/cordbscs.o cord/cordxtra.o cord/cordprnt.o - -SRCS= $(CSRCS) mips_sgi_mach_dep.S rs6000_mach_dep.s alpha_mach_dep.S \ - sparc_mach_dep.S include/gc.h include/gc_typed.h \ - include/private/gc_hdrs.h include/private/gc_priv.h \ - include/private/gcconfig.h include/private/gc_pmark.h \ - include/gc_inl.h include/gc_inline.h include/gc_mark.h \ - threadlibs.c if_mach.c if_not_there.c gc_cpp.cc include/gc_cpp.h \ - gcname.c include/weakpointer.h include/private/gc_locks.h \ - gcc_support.c mips_ultrix_mach_dep.s include/gc_alloc.h \ - include/new_gc_alloc.h include/gc_allocator.h \ - include/javaxfc.h sparc_sunos4_mach_dep.s sparc_netbsd_mach_dep.s \ - include/private/solaris_threads.h include/gc_backptr.h \ - hpux_test_and_clear.s include/gc_gcj.h \ - include/gc_local_alloc.h include/private/dbg_mlc.h \ - include/private/specific.h powerpc_macosx_mach_dep.s \ - include/leak_detector.h include/gc_amiga_redirects.h \ - include/gc_pthread_redirects.h ia64_save_regs_in_stack.s \ - $(CORD_SRCS) - -DOC_FILES= README.QUICK doc/README.Mac doc/README.MacOSX doc/README.OS2 \ - doc/README.amiga doc/README.cords doc/debugging.html \ - doc/README.dj doc/README.hp doc/README.linux doc/README.rs6000 \ - doc/README.sgi doc/README.solaris2 doc/README.uts \ - doc/README.win32 doc/barrett_diagram doc/README \ - doc/README.contributors doc/README.changes doc/gc.man \ - doc/README.environment doc/tree.html doc/gcdescr.html \ - doc/README.autoconf doc/README.macros doc/README.ews4800 \ - doc/README.DGUX386 doc/README.arm.cross - -TESTS= tests/test.c tests/test_cpp.cc tests/trace_test.c \ - tests/leak_test.c tests/thread_leak_test.c - -GNU_BUILD_FILES= configure.in Makefile.am configure acinclude.m4 \ - libtool.m4 install-sh configure.host Makefile.in \ - ltconfig aclocal.m4 config.sub config.guess \ - ltmain.sh mkinstalldirs depcomp missing - -OTHER_MAKEFILES= OS2_MAKEFILE NT_MAKEFILE NT_THREADS_MAKEFILE gc.mak \ - BCC_MAKEFILE EMX_MAKEFILE WCC_MAKEFILE Makefile.dj \ - PCR-Makefile SMakefile.amiga Makefile.DLLs \ - digimars.mak Makefile.direct -# Makefile and Makefile.direct are copies of each other. - -OTHER_FILES= Makefile setjmp_t.c callprocs pc_excludes \ - MacProjects.sit.hqx MacOS.c \ - Mac_files/datastart.c Mac_files/dataend.c \ - Mac_files/MacOS_config.h Mac_files/MacOS_Test_config.h \ - add_gc_prefix.c gc_cpp.cpp win32_threads.c \ - version.h AmigaOS.c \ - $(TESTS) $(GNU_BUILD_FILES) $(OTHER_MAKEFILES) - -CORD_INCLUDE_FILES= $(srcdir)/include/gc.h $(srcdir)/include/cord.h \ - $(srcdir)/include/ec.h $(srcdir)/include/private/cord_pos.h - -UTILS= if_mach if_not_there threadlibs - -# Libraries needed for curses applications.

(See gc_priv.h for consequences.) -# -DSMALL_CONFIG tries to tune the collector for small heap sizes, -# usually causing it to use less space in such situations. -# Incremental collection no longer works in this case. -# -DLARGE_CONFIG tunes the collector for unusually large heaps. -# Necessary for heaps larger than about 500 MB on most machines. -# Recommended for heaps larger than about 64 MB. -# -DDONT_ADD_BYTE_AT_END is meaningful only with -# -DALL_INTERIOR_POINTERS. Normally -DALL_INTERIOR_POINTERS -# causes all objects to be padded so that pointers just past the end of -# an object can be recognized. This can be expensive. (The padding -# is normally more than one byte due to alignment constraints.) -# -DDONT_ADD_BYTE_AT_END disables the padding. -# -DNO_SIGNALS does not disable signals during critical parts of -# the GC process. This is no less correct than many malloc -# implementations, and it sometimes has a significant performance -# impact. However, it is dangerous for many not-quite-ANSI C -# programs that call things like printf in asynchronous signal handlers. -# This is on by default. Turning it off has not been extensively tested with -# compilers that reorder stores. It should have been. -# -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not -# have execute permission, i.e. it may be impossible to execute -# code from the heap. Currently this only affects the incremental -# collector on UNIX machines. It may greatly improve its performance, -# since this may avoid some expensive cache synchronization. -# -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support -# the new syntax "operator new[]" for allocating and deleting arrays. -# See gc_cpp.h for details. No effect on the C part of the collector. -# This is defined implicitly in a few environments. Must also be defined -# by clients that use gc_cpp.h. -# -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined -# as aliases for X, GC_realloc, and GC_free, respectively. -# Calloc is redefined in terms of the new malloc. X should -# be either GC_malloc or GC_malloc_uncollectable. -# The former is occasionally useful for working around leaks in code -# you don't want to (or can't) look at. It may not work for -# existing code, but it often does. Neither works on all platforms, -# since some ports use malloc or calloc to obtain system memory. -# (Probably works for UNIX, and win32.) -# -DIGNORE_FREE turns calls to free into a noop. Only useful with -# -DREDIRECT_MALLOC. -# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls. -# Reduces code size slightly at the expense of debuggability. -# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of -# order by specifying a nonstandard finalization mark procedure (see -# finalize.c). Objects reachable from finalizable objects will be marked -# in a sepearte postpass, and hence their memory won't be reclaimed. -# Not recommended unless you are implementing a language that specifies -# these semantics. Since 5.0, determines only only the initial value -# of GC_java_finalization variable. -# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response -# to explicit GC_invoke_finalizers() calls. -# In 5.0 this became runtime adjustable, and this only determines the -# initial value of GC_finalize_on_demand. -# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable. -# This is useful if either the vendor malloc implementation is poor, -# or if REDIRECT_MALLOC is used. -# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly -# sets the heap block size. Each heap block is devoted to a single size and -# kind of object. For the incremental collector it makes sense to match -# the most likely page size. Otherwise large values result in more -# fragmentation, but generally better performance for large heaps. -# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever -# the garbage collector detects a value that looks almost, but not quite, -# like a pointer, print both the address containing the value, and the -# value of the near-bogus-pointer. Can be used to identifiy regions of -# memory that are likely to contribute misidentified pointers. -# -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers -# for objects allocated with the debugging allocator. If all objects -# through GC_MALLOC with GC_DEBUG defined, this allows the client -# to determine how particular or randomly chosen objects are reachable -# for debugging/profiling purposes. The gc_backptr.h interface is -# implemented only if this is defined. -# -DGC_ASSERTIONS Enable some internal GC assertion checking. Currently -# this facility is only used in a few places. It is intended primarily -# for debugging of the garbage collector itself, but could also -# -DDBG_HDRS_ALL Make sure that all objects have debug headers. Increases -# the reliability (from 99.9999% to 100%) of some of the debugging -# code (especially KEEP_BACK_PTRS). Makes -DSHORT_DBG_HDRS possible. -# Assumes that all client allocation is done through debugging -# allocators. -# -DSHORT_DBG_HDRS Assume that all objects have debug headers. Shorten -# the headers to minimize object size, at the expense of checking for -# writes past the end of an object. This is intended for environments -# in which most client code is written in a "safe" language, such as -# Scheme or Java. Assumes that all client allocation is done using -# the GC_debug_ functions (or through the macros that expand to these. -# (Also eliminates the field for the requested object size.) -# occasionally be useful for debugging of client code. Slows down the -# collector somewhat, but not drastically. -# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly -# altered stubborn objects, at substantial performance cost. -# Use only for debugging of the incremental collector. -# -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems -# that include a pointer to a type descriptor in each allocated object). -# Building this way requires an ANSI C compiler. -# -DUSE_I686_PREFETCH causes the collector to issue Pentium III style -# prefetch instructions. No effect except on X86 Linux platforms. -# Assumes a very recent gcc-compatible compiler and assembler. -# (Gas prefetcht0 support was added around May 1999.) -# Empirically the code appears to still run correctly on Pentium II -# processors, though with no performance benefit. May not run on other -# X86 processors? In some cases this improves performance by -# 15% or so. -# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style -# prefetch instructions. Same restrictions as USE_I686_PREFETCH. -# UNTESTED!! -# -DGC_USE_LD_WRAP in combination with the gld flags listed in README.linux -# causes the collector some system and pthread calls in a more transparent -# fashion than the usual macro-based approach.

A few of the files needed -to use the GNU-style build procedure come with a modified GPL license -that appears not to significantly restrict use of the collector, though -use of those files for a purpose other than building the collector may -require the resulting code to be covered by the GPL. - -For more details and the names of other contributors, see the -doc/README* files and include/gc.h. This file describes typical use of -the collector on a machine that is already supported. - -For the version number, see doc/README or version.h. - -INSTALLATION: -Under UN*X, Linux: -Alternative 1 (the old way): type "make test" in this directory. - Link against gc.a. - -Alternative 2 (the new way): type - "./configure --prefix=<dir>; make; make check; make install". - Link against <dir>/lib/libgc.a or <dir>/lib/libgc.so. - See README.autoconf for details - -Under OS/2 or Windows 95, 98, Me, NT, or 2000: -copy the appropriate makefile to MAKEFILE, read it, and type "nmake test". -(Under Windows, this assumes you have Microsoft command-line tools -installed, and have DOS configured with enough environment space to run them.) -Read the machine specific README in the doc directory if one exists. -The only way to develop code with the collector for Windows 3.1 is -to develop under Windows NT or 95+, and then to use win32S. - -If you need thread support, you will need to either follow the special -platform-dependent instructions (win32), or add a suitable define -option as described in Makefile. - -If you wish to use the cord (structured string) library, type -"make cords". (This requires an ANSI C compiler. You may need -to redefine CC in the Makefile. The CORD_printf implementation in -cordprnt.c is known to be less than perfectly portable. The rest -of the package should still work.) - -If you wish to use the collector from C++, type -"make c++". These add further files to gc.a and to the include -subdirectory. See cord/cord.h and include/gc_cpp.h. - -TYPICAL USE: -Include "gc.h" from the include subdirectory. Link against the -appropriate library ("gc.a" under UN*X). Replace calls to malloc -by calls to GC_MALLOC, and calls to realloc by calls to GC_REALLOC. -If the object is known to never contain pointers, use GC_MALLOC_ATOMIC -instead of GC_MALLOC. - -Define GC_DEBUG before including gc.h for additional checking. - -More documentation on the collector interface can be found at -http://www.hpl.hp.com/personal/Hans_Boehm/gc/gcinterface.html, -in doc/README, and in include/gc.h . - -WARNINGS: - -Do not store the only pointer to an object in memory allocated -with system malloc, since the collector usually does not scan -memory allocated in this way. - -Use with threads may be supported on your system, but requires the -collector to be built with thread support. See Makefile. The collector -does not guarantee to scan thread-local storage (e.g. of the kind -accessed with pthread_getspecific()). The collector does scan -thread stacks though, so generally the best solution is to ensure that -any pointers stored in thread-local storage are also stored on the -thread's stack for the duration of their lifetime. - diff --git a/gc/SMakefile.amiga b/gc/SMakefile.amiga @@ -1,178 +0,0 @@ - -# Rewritten smakefile for amiga / sas/c. -Kjetil M. -# Dont use the cord-package if you define parm=both or parm=reg. - - -#----------------TOOLS-------------------------------- -CC=sc -LINKER=slink -LIBER=oml - -#----------------CPU OPTIONS-------------------------- - -CPU=68060 - -#----------------FPU OPTIONS-------------------------- - -MATH=8 -MATHLIB=LIB:scm881.lib - -#----------------COMPILER OPTIONS--------------------- - -IGNORE= IGNORE=85 IGNORE=154 IGNORE=161 IGNORE=100 - -OPTIMIZE=optimize optimizetime optglobal optimizerdepth=100 optimizerpeephole optloop OPTSCHED optimizerinlocal optimizerrecurdepth=100 -# optimizerinline optimizercomplexity=100 - -OPT= $(OPTIMIZE) CPU=$(CPU) math=$(MATH) NOSTACKCHECK VERBOSE \ -MAPHUNK NOVERSION NOICONS nodebug \ -DEFINE SILENT \ -parm=reg \ -DEFINE __USE_SYSBASE - - -SOPT= $(OPT) $(IGNORE) \ -DEFINE AMIGA_SKIP_SEG \ -DEFINE ATOMIC_UNCOLLECTABLE \ -DEFINE GC_AMIGA_FASTALLOC \ -DEFINE GC_AMIGA_RETRY \ -DEFINE GC_AMIGA_PRINTSTATS \ -DEFINE GC_AMIGA_GC - - -#DEFINE ALL_INTERIOR_POINTERS \ - - -SCOPT= $(SOPT) define GC_AMIGA_MAKINGLIB - -CSCOPT= $(OPT) DEFINE AMIGA IGNORE=100 IGNORE=161 - -#------------------LINKING---------------------------- - - -all: gctest setjmp_t cord/cordtest - -clean: - delete *.lib gctest setjmp_t *.o *.lnk cord/*.o cord/*.lib cord/*.lnk cord/cordtest - smake - -test: setjmp_t gctest cord/cordtest - setjmp_t - gctest - cord/cordtest - -gctest: gc$(CPU).lib GCAmigaOS$(CPU).lib test.o - $(LINKER) LIB:c.o test.o TO gctest LIB gc$(CPU).lib LIB:sc.lib $(MATHLIB) - -setjmp_t: setjmp_t.o gc.h - $(LINKER) LIB:c.o setjmp_t.o to setjmp_t lib LIB:sc.lib - -cord/cordtest: cord/cordtest.o cord/cord$(CPU).lib gc$(CPU).lib - slink LIB:c.o cord/cordtest.o LIB $(MATHLIB) gc$(CPU).lib cord/cord$(CPU).lib LIB:sc.lib TO cord/cordtest - - -#------------------LIBBING---------------------------- - -OBJS= alloc.o reclaim.o allchblk.o misc.o mach_dep.o os_dep.o mark_rts.o headers.o mark.o obj_map.o blacklst.o finalize.o new_hblk.o real_malloc.o dyn_load.o dbg_mlc.o malloc.o stubborn.o checksums.o typd_mlc.o ptr_chck.o mallocx.o - -gc$(CPU).lib: $(OBJS) - $(LIBER) gc$(CPU).lib r $(OBJS) - - -COBJS = cord/cordbscs.o cord/cordprnt.o cord/cordxtra.o - -cord/cord$(CPU).lib: $(COBJS) - oml cord/cord$(CPU).lib r $(COBJS) - -#------------------COMPILING-------------------------- - -INC= gc_private.h gc_hdrs.h gc.h gcconfig.h - -alloc.o : alloc.c $(INC) - $(CC) alloc.c $(SCOPT) ignore=7 - -reclaim.o : reclaim.c $(INC) - $(CC) reclaim.c $(SCOPT) - -allchblk.o : allchblk.c $(INC) - $(CC) allchblk.c $(SCOPT) - -misc.o : misc.c $(INC) - $(CC) misc.c $(SCOPT) - -os_dep.o : os_dep.c $(INC) AmigaOS.c - $(CC) os_dep.c $(SCOPT) - -mark_rts.o : mark_rts.c $(INC) - $(CC) mark_rts.c $(SCOPT) - -headers.o : headers.c $(INC) - $(CC) headers.c $(SCOPT) - -mark.o : mark.c $(INC) - $(CC) mark.c $(SCOPT) - -obj_map.o : obj_map.c $(INC) - $(CC) obj_map.c $(SCOPT) - -blacklst.o : blacklst.c $(INC) - $(CC) blacklst.c $(SCOPT) - -finalize.o : finalize.c $(INC) - $(CC) finalize.c $(SCOPT) noopt #Could sas/c still have problems with this one?
