Subject: sparc: Use match_code in zero_or_v7_operand.
X-Git-Tag: releases/gcc-4.7.0~824
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f1d4a790ec622a2c905b4b1e379731d670450470;p=thirdparty%2Fgcc.git

sparc: Use match_code in zero_or_v7_operand.

Failure to do so means that genpreds doesn't know that we're
matching a const_int, and it generates the wrong mode test.

        * config/sparc/predicates.md (zero_or_v7_operand): Use match_code.
