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. +# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response +# to explicit GC_invoke_finalizers() calls. +# -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. +# -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. +# -DOLD_BLOCK_ALLOC Use the old, possibly faster, large block +# allocation strategy. The new strategy tries harder to minimize +# fragmentation, sometimes at the expense of spending more time in the +# large block allocator and/or collecting more frequently. +# + + + +LIBGC_CFLAGS= -O -DNO_SIGNALS -DSILENT \ + -DREDIRECT_MALLOC=GC_malloc_uncollectable \ + -DDONT_ADD_BYTE_AT_END -DALL_INTERIOR_POINTERS +# Flags for building libgc.a -- the last two are required. + +CXXFLAGS= $(CFLAGS) +AR= ar +RANLIB= ranlib + + +# Redefining srcdir allows object code for the nonPCR version of the collector +# to be generated in different directories.
