Add a avoidWriteAfterWrite() target hook to identify register classes that suffer from write-after-write hazards. For those register classes, try to avoid writing the same register in two consecutive instructions. This is currently disabled by default. We should not spill to avoid hazards! The command line flag -avoid-waw-hazard can be used to enable waw avoidance. llvm-svn: 129772 |
