Hello! Attached patch checks support for sahf in 64bit mode and rewrites logic to output sahf accordingly. 2010-05-20 Uros Bizjak <ubizjak@gmail.com> PR target/43733 * configure.ac (gcc_cv_as_ix86_sahf): Switch to 64bit mode. * configure: Regenerate. * config.in: Regenerate. * config/i386/i386.md (x86_sahf_1): Conditionally output 0x9e instead of sahf only for 64bit targets. Patch was tested on x86_64-pc-linux-gnu, and also by the reporter. Patch was committed to mainline, will be committed to other branches after a couple of days. Uros.
