Compile the testcase with:
.../cc1 -fpreprocessed libgcc2.i  -g -O2   -fnon-call-exceptions -o libgcc2.s
This results in an ICE in reload_cse_simplify_operands, since an earlyclobber
output has been allocated the same register as an input of an asm template.

--- Comment #2 from Oleg Endo <olegendo at gcc dot gnu.org> ---
I've tried this on rev 205674 (4.9) and it seems that time has fixed the issue.
