powerpc-eabi-gcc compatible with Diab-Data CC ?
Fri Aug 18 10:16:00 GMT 2000
We've done essentially that with our PPC403 software.ÃÂ There are
many issues to deal with, but I can say that it does in fact use R2 and
R13 for the same purpose as Diab's compiler.ÃÂ ÃÂ We use the
following compiler options:
ÃÂ -meabi -mcpu=403 -mregnames\
ÃÂ -msoft-float -mmultiple -mbig-endian -msdata=eabi -c
ÃÂ -Wall -Wno-format -Wno-parentheses -Wno-main -fno-builtin
The important one is -meabi, so you get eabi register usage like
Diab.ÃÂ Feel free to email me any other questions you have;ÃÂ it
took us a long time to migrate successfully from Diab to GCC, and I'd be
glad to help.

Does anybody know if that's possible?
If so, what command line options do I need to
supply to GCC?
I found I 1997 post to this list in which
someone seems to indicate that he's done that.
(looking at the .s output of my powerpc-eabi-gcc,
it doesn't seem to use registers R2 and R13 to
access sections .sdata and .sbss like the Diab
compiler does.....doesn't look very compatible
