Yes, I'm using gcc 3.3.2
I think the problem with the asm-statements is not using %M to get a
register list but the usage of symbolic names for operands (%[name]
instead of %0). You could try replacing
__asm__(
"ldmia %[glbl_tsc], %M[tsc]\n"
: /* output */ [tsc] "=r" (tsc.ll)
: /* input */ [glbl_tsc] "r" (&ep93xx_tsc.ll),
"m" (ep93xx_tsc)
);
with
__asm__(
"ldmia %1, %M0\n"
: /* output */ "=r" (tsc.ll)
: /* input */ "r" (&ep93xx_tsc.ll),
"m" (ep93xx_tsc)
);
