### Magic Makefile for descore
# Interesting defines are sparc, mc68000, vax and i386
# Rely on gcc defining them appropriately.
# CPPFLAGS= -Dsparc # use 6+8 general regs
# CPPFLAGS= -Dmc68000 # use 3+4 addr (1+4 live), and 3+3 data regs
# CPPFLAGS= -Dvax # use 6+0 general regs
# CPPFLAGS= -Di386 # use 3+0 regs, and 3+0 normal variables
CODEGEN.c= $(CC) $(CFLAGS) $(CPPFLAGS) -S
COMPILE.c= $(CC) $(CFLAGS) $(CPPFLAGS) -c
LINK.c= $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS)
# hand-entered files that go into the library
SC= desKerb.c desUtil.c desQuick.c
SO= desKerb.o desUtil.o desQuick.o
