# Primary targets:
# gc.a - builds basic library
# libgc.a - builds library for use with g++ "-fgc-keyword" extension
# 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$(EXE_SUFFIX) - builds dumb editor based on cords.

CFLAGS= -O -DNO_SIGNALS -DALL_INTERIOR_POINTERS -DSILENT -DATOMIC_UNCOLLECTABLE
# Setjmp_test may yield overly optimistic results when compiled
# without optimization.
# -DSILENT disables statistics printing, and improves performance.
# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
# altered stubborn objects, at substantial performance cost.
# Use only for incremental collector debugging.
# -DFIND_LEAK 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.
# -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
# (Clients should also define SOLARIS_THREADS and then include
# gc.h before performing thr_ or dl* or GC_ operations.)
# This is broken on nonSPARC machines.
# -DIRIX_THREADS enables support for Irix pthreads. See README.irix.
# -DALL_INTERIOR_POINTERS allows all pointers to the interior
# of objects to be recognized. (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.
# -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.
# -DOPERATOR_NEW_ARRAY declares that the C++ compiler supports 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.
# -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.
# -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.
