- Subject: Should -march=iwmmxt work?
Right now arm-elf-gcc -march=iwmmxt will try to pass -march=iwmmxt to gas,
which does not recognize it. And the comment in tc-arm.c says:
/* This list should, at a minimum, contain all the architecture names
recognized by GCC. */
static struct arm_arch_option_table arm_archs[] =
So is this patch OK? I'm not sure why -march=xscale defaults to VFP (soft)
and -mcpu=xscale defaults to VFP_V2 (hard, right?), but I maintained
consistency.
