# Primary targets:
# gc.a - builds basic library
# c++ - adds C++ interface to library and include directory
# cords - adds cords (heavyweight strings) to library and include directory
# 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.
CC= cc
CXX=g++ -ansi
# Needed only for "make c++", which adds the c++ interface
AS=as
CFLAGS= -O -DSILENT -DALL_INTERIOR_POINTERS -DNO_SIGNALS
# 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.
# -DFIND_LEAK causes the collector to assume that all inaccessible
# objects should have been explicitly deallocated, and reports exceptions
# -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.
# -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.
# -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.
# -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.
