# Syn68k uses inline assembly that confuses various gcc stack optimizations.
# Under gcc 2.x -fno-defer-pop is sufficient to get gcc to do the right thing
# with our code. Under gcc 3.x we need to also add -maccumulate-outgoing-args.
# Since we don't know what gcc we have until we try to execute CC, we
# do a test right here to figure out if the c-compiler understands
# -maccumulate-outgoing-args. If it does, we use it.
#
# A better solution would be to put something into our asm to form a
# barrier that gcc won't try to do stack optimizations across. I haven't yet
# scoured the gcc 3 documentation or source code to see if there's something
# obvious that can be used.
