You didn't mention the binutils version or how it was configured. It
GNU assembler 2.16.91 20050809
Bintutils used the same configure script as what I used for gcc.
I've been reading (googling) up on this problem as it seems I am not the
first to have it. The problem also seems quite complicated.
Binutils was configured with (among other options) "--with-cpu=7400" and
"--enable-altivec". It can and does compile altivec instructions fine.
It's just I can't get gcc and xgcc to pass that to the assembler. I
thought the "--with-cpu" option was supposed to do that? i.e. default to a
particular cpu. Looking at the specs file for the host compiler the
default is -mppc. When I gave the "--with-cpu=7400" shouldn't that have
made the default -m7400?. What about xgcc, how can I make that use the
7400 cpu?
Maybe I'll also ask folks on the binutils mailing list.
There is a TARGET_LIBGCC2_CFLAGS that is used when compiling libgcc2
instead of the normal CFLAGS_FOR_TARGET. You could add extra -m options
here. That would solve your immediate problem, but you still would have
a mismatch between gcc and binutils.
It didn't work for me but I could have something else preventing it from
working.
