+# 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 - builds dumb editor based on cords.

+CFLAGS= -O -DNO_SIGNALS -DALL_INTERIOR_POINTERS -DSILENT
+
+# Setjmp_test may yield overly optimistic results when compiled
+# without optimization.
+# -DSILENT disables statistics printing, and improves performance.
+# -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.
+# -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.
