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, 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.) +# -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 and +# Linux 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. Turns on call chain saving on X86. On X86, client +# code should NOT be compiled with -fomit-frame-pointer. +# -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. 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? +# -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. +# + +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 + +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 + +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/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 $(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 + +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 \ + aclocal.m4 config.sub config.guess ltconfig \ + ltmain.sh mkinstalldirs + +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.
