[Bug middle-end/27906] New: reload allocates register of live register variable to earlyclobber output

["amylaar at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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.
