# The way we use labels in our assembler is out of spec. The gcc info
|
|
# pages say that you're not allowed to jump between labels of asm.
|
|
# Historically, however, we chose not to put everything into a single
|
|
# function and then jump about within spec. IIRC, that was either due
|
|
# to the compilation time and memory consumption to be excessive
|
|
# and/or due to us running into compiler bugs. This was all back
|
|
# around 1995 though and we have more memory and better compilers. As
|
|
# such, it may make sense to re-evaluate the decision to split all the
|
|
# opcodes into separate functions. However, until we do that, we need
|
|
# to deal with the fact that some dead-code-elimination (DCE)
|
|
# optimizations will cause our trickery to fail. As such, we include
|
|
# "-fno-dce" in the architectures where we know we're going to have trouble.

# 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.
