Hi Andrew,
Thanks for your answer.
The documentation only mentions the size of int and pointer types.
The gcc documentation talks only about gcc; you're asking about the
system linker.
I did not mean that.
If I compile a.c with "gcc-x.x.x (32 bits)" on a Pentium 4 machine, and
with "gcc-x.x.x (64 bits) -m32" on an Opteron, am I guaranteed that both
a.o will have the same contents?
Any risk that the file compiled on Opteron contains Opteron-only
instructions for instance? Or references only 64 bits variants of some
system structures?
If I compile a.c with "gcc-x.x.x (32 bits)" on a Pentium 4 machine, and
b.c with "gcc-x.x.x (64 bits) -m32" on an Opteron, I need to be able to
link a.o and b.o together and that the result is actually meaningful on
a Pentium 4.
Regards,
Christophe.
