#
# This Makefile is set up to make a debugging malloc called libmalloc_d.a
# Also generates testmalloc and simumalloc, two regression tests.
#
# To make a production malloc, type 'make clean libmalloc'
#
# If you're impatient, and want it all in one file, type 'make one'
# and it'll merge the all the source into one file. Bit bigger, but
# avoids Unix linker misunderstandings if these are not in libc, and
# ensures the debugging routines are linked in whether called or not.
# On some machines, mv onefile.o libmalloc_d.a will work. On some, it
# upsets the linker and you will need to "ar ruv libmalloc_d.a onefile.o".
#
# 'make dist' runs 'bundle' to create a shell archive on stdout.
#
# 'make veryclean' cleans out lib*.a as well.
#
# 'make depend' runs 'mkdep' (from BSD src or named) to create dependencies.
#
# 'make install' puts all the OBJS in $(ARCHIVE), ranlibs it, and
# puts malloc.h in INCDIR.
#

# neutralize SystemV genius
SHELL=/bin/sh

# DEBUGDEFS are set for libmalloc_d.a. Say 'make libmalloc' for nondebug
# version. (DEBUGDEFS=$(FASTDEFS))
#
DEBUGDEFS=-DDEBUG -DTRACE -DPROFILESIZES

# FASTDEFS are used when the 'libmalloc' target is made.
#
# -DTRACE and -DPROFILESIZES shouldn't introduce very much overhead since the
# former is turned off (one 'if'), and the latter is one 'if' + increment.
# So you can keep them even in the fast production version. 
# You may want to define -DBUGCOMPATIBILITY if you want malloc(0) to
# do the same thing as malloc(1). Some suntools programs expect this 
# behaviour. So does Xlib, and the X server has done it at least once.
# (Note that SVID requires malloc(0) to return NULL, and the 
# May 13, 1988 ANSI C draft says that you can either return a NULL pointer
# or a unique pointer (typically decisive standard...) 
#
FASTDEFS=#-DBUGCOMPATIBILITY -DTRACE -DPROFILESIZES


#  NORMALDEFS are used for both debugging and non-debugging versions
# -DSHORTNAMES makes sure all internal global symbols are unique within 6
# characters. Avoid defining unless your linker is braindead.
# -DUSESTDIO is to make this use fputs() instead of write() for trace
# and debugging output. write() is preferable since it is unbuffered,
# and does not call malloc() or suchlike. Avoid defining if possible.
# -DSTDHEADERS if you have ANSI standard header files (stdlib.h, string.h)
# This can be defined on Solaris2.1, Irix3.3.x, BSD3.3,
# 386BSD, BSD386 and other sufficiently Posix systems.
# -DHAVE_MMAP should be defined for SunOS4.x and other systems
# that have a general purpose mmap call that allows memory-mapped files.
#
