+ # This is the original manually generated Makefile.  It may still be used
+ # to build the collector.
+ #
+ # Primary targets:
+ # gc.a - builds basic library
+ # c++ - adds C++ interface to library
+ # cords - adds cords (heavyweight strings) to library
+ # test - prints porting information, then builds basic version of gc.a,
+ #              and runs some tests of collector and cords.  Does not add 
cords or
+ #      c++ interface to gc.a
+ # cord/de - builds dumb editor based on cords.
+ ABI_FLAG= 
+ # ABI_FLAG should be the cc flag that specifies the ABI.  On most
+ # platforms this will be the empty string.  Possible values:
+ # +DD64 for 64-bit executable on HP/UX.
+ # -n32, -n64, -o32 for SGI/MIPS ABIs.
+ 
+ AS_ABI_FLAG=$(ABI_FLAG)
+ # ABI flag for assembler.  On HP/UX this is +A64 for 64 bit
+ # executables.
+ 
+ CC=cc $(ABI_FLAG)
+ CXX=g++ $(ABI_FLAG)
+ AS=as $(AS_ABI_FLAG)
+ #  The above doesn't work with gas, which doesn't run cpp.
+ #  Define AS as `gcc -c -x assembler-with-cpp' instead.
+ 
+ # Redefining srcdir allows object code for the nonPCR version of the collector
+ # to be generated in different directories.
+ srcdir= .
+ VPATH= $(srcdir)
+ 
+ CFLAGS= -O -I$(srcdir)/include -DATOMIC_UNCOLLECTABLE -DNO_SIGNALS 
-DNO_EXECUTE_PERMISSION -DSILENT -DALL_INTERIOR_POINTERS
+ 
+ # To build the parallel collector on Linux, add to the above:
+ # -DGC_LINUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC
+ # To build the parallel collector in a static library on HP/UX,
+ # add to the above:
+ # -DGC_HPUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC -DUSE_HPUX_TLS 
-D_POSIX_C_SOURCE=199506L
+ # To build the thread-safe collector on Tru64, add to the above:
+ # -pthread -DGC_OSF1_THREADS
+ 
+ # HOSTCC and HOSTCFLAGS are used to build executables that will be run as
+ # part of the build process, i.e. on the build machine.  These will usually
+ # be the same as CC and CFLAGS, except in a cross-compilation environment.
+ # Note that HOSTCFLAGS should include any -D flags that affect thread support.
+ HOSTCC=$(CC)
+ HOSTCFLAGS=$(CFLAGS)
+ 
+ # For dynamic library builds, it may be necessary to add flags to generate
+ # PIC code, e.g. -fPIC on Linux.
+ 
+ # Setjmp_test may yield overly optimistic results when compiled
+ # without optimization.
+ 
+ # These define arguments influence the collector configuration:
+ # -DSILENT disables statistics printing, and improves performance.
+ # -DFIND_LEAK causes GC_find_leak to be initially set.
+ #   This causes the collector to assume that all inaccessible
+ #   objects should have been explicitly deallocated, and reports exceptions.
+ #   Finalization and the test program are not usable in this mode.
+ # -DGC_SOLARIS_THREADS enables support for Solaris (thr_) threads.
+ #   (Clients should also define GC_SOLARIS_THREADS and then include
+ #   gc.h before performing thr_ or dl* or GC_ operations.)
+ #   Must also define -D_REENTRANT.
+ # -DGC_SOLARIS_PTHREADS enables support for Solaris pthreads.
+ #   (Internally this define GC_SOLARIS_THREADS as well.)
+ # -DGC_IRIX_THREADS enables support for Irix pthreads.  See README.irix.
+ # -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads.
+ #   Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L. See README.hp.
+ # -DGC_LINUX_THREADS enables support for Xavier Leroy's Linux threads.
+ #   see README.linux.  -D_REENTRANT may also be required.
+ # -DGC_OSF1_THREADS enables support for Tru64 pthreads.  Untested.
+ # -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads.  Untested.
+ #   Appeared to run into some underlying thread problems.
+ # -DGC_MACOSX_THREADS enables support for Mac OS X pthreads.  Untested.
+ # -DGC_DGUX386_THREADS enables support for DB/UX on I386 threads.
+ #   See README.DGUX386.
+ # -DGC_WIN32_THREADS enables support for win32 threads.  That makes sense
+ #   for this Makefile only under Cygwin.
+ # -DGC_THREADS should set the appropriate one of the above macros.
+ #   It assumes pthreads for Solaris.
+ # -DALL_INTERIOR_POINTERS allows all pointers to the interior
+ #   of objects to be recognized.  (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 to be defined as alias for X.
+ #   Unless the following macros are defined, realloc is also redirected
+ #   to GC_realloc, and free is redirected to GC_free.
+ #   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.
+ #   It requires that the following two macros also be used.)
+ #   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.
+ #   This also requires the following:
+ # -DREDIRECT_FREE=X causes free to be redirected to X.  The
+ #   canonical use is -DREDIRECT_FREE=GC_debug_free.
+ # -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.
+ # -DUSE_PPC_PREFETCH causes the collector to issue PowerPC style
+ #   prefetch instructions.  No effect except on PowerPC OS X platforms.
+ #   Performance impact untested.
+ # -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 
pthread_support.c.
+ #   (Similar code should work on Solaris or Irix, but it hasn't been tried.)
+ # -DTEST_WITH_SYSTEM_MALLOC causes gctest to allocate (and leak) large chunks
+ #   of memory with the standard system malloc.  This will cause the root
+ #   set and collected heap to grow significantly if malloced memory is
+ #   somehow getting traced by the collector.  This has no impact on the
+ #   generated library; it only affects the test.
+ # -DPOINTER_MASK=0x... causes candidate pointers to be ANDed with the
+ #   given mask before being considered.  If either this or the following
+ #   macro is defined, it will be assumed that all pointers stored in
+ #   the heap need to be processed this way.  Stack and register pointers
+ #   will be considered both with and without processing.
+ #   These macros are normally needed only to support systems that use
+ #   high-order pointer tags. EXPERIMENTAL.
+ # -DPOINTER_SHIFT=n causes the collector to left shift candidate pointers
+ #   by the indicated amount before trying to interpret them.  Applied
+ #   after POINTER_MASK. EXPERIMENTAL.  See also the preceding macro.
