Hello! Just a small optimization, we can reject non-register RTXes and wrong subregs from index early. No functional change - these RTXes were rejected in ix86_legitimate_address_p anyway. 2011-07-21 Uros Bizjak <ubizjak@gmail.com> * config/i386/i386.c (ix86_decompose_address): Reject all but register operands and DImode hard registers in index. Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN. Uros.
