i was trying to cross-compile glibc-2.4 with gcc-4.1.1 when it failed on me while building ioperm.c ... poking around a bit, looks like the same issue discussed here: http://gcc.gnu.org/ml/gcc/2005-07/msg00371.html however, this seems to have stalled ?
the glibc build system appends -Wa,-mev6 to the CFLAGS for ioperm.c, but when
gcc is run without a -mcpu flag (or with ev4/ev5 specified), the resulting
asm produced includes '.arch ev4' or '.arch ev5', and then gas aborts with
the fun errors:
{standard input}: Assembler messages:
{standard input}:181: Error: macro requires $at register while noat in effect
{standard input}:199: Error: macro requires $at register while noat in effect
{standard input}:235: Error: macro requires $at register while noat in effect
{standard input}:255: Error: macro requires $at register while noat in effect
and of course, adding -mcpu=ev6 or better to CFLAGS works just peachy
