Subject: Remove the cl-no-signed-zeros cc1 option
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a932bb93b0638f3ee23901339849d1ed6f160756;p=platform%2Fupstream%2Fllvm.git

Remove the cl-no-signed-zeros cc1 option

Use the driver flag -fno-signed-zeros instead.

This was recommended but not implemented in D6873:
http://reviews.llvm.org/D6873

which was checked in at r226915:
http://reviews.llvm.org/rL226915

llvm-svn: 234093
