Testsuite fails on PowerPC with: Re: [PATCH][middle-end][i386][version 6]Add -fzero-call-used-regs=[skip|used-gpr-arg|used-arg|all-gpr-arg|all-arg|used-gpr|all-gpr|used|all])

[Tobias Burnus]

Three of the testcases fail on PowerPC: 
gcc.target/i386/zero-scratch-regs-{9,10,11}.c
  powerpc64le-linux-gnu/default/gcc.d/zero-scratch-regs-10.c:77:1: sorry, 
unimplemented: '-fzero-call-used_regs' not supported on this target

Did you miss some dg-require-effective-target ?
