// 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 GC_ operations.)
// This is broken on nonSPARC machines.
// -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.

// -DGC_OPERATOR_NEW_ARRAY declares that the C++ compiler supports the
1999-04-07 10:01:30 +02:00
// 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.)
// -DNO_DEBUG removes GC_dump and the debugging routines it calls.
// Reduces code size slightly at the expense of debuggability.
