Hello! 2013-03-25 Uros Bizjak <ubizjak@gmail.com> * config/i386/i386.md (*zero_extendsidi2): Merge with *zero_extendsidi2_rex64. Use x64 and nox64 isa attributes. * config/i386/predicates.md (x86_64_zext_operand): Rename from x86_64_zext_general_operand. Use nonimmediate_operand on 32bit targets. Clarify comment. Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN. Uros.
