Hello! Attached patch extends TARGET_READ_MODIFY{,_WRITE} peepholes to handle all integer modes, while also taking care not to introduce additional QImode register stalls. While looking at the insn enable condition, I noticed that we don't use "probe_stack" pattern any more, as the stack check loop is now implemented in a different way. 2016-04-28 Uros Bizjak <ubizjak@gmail.com> * config/i386/i386.md (peephole2s for operations with memory inputs): Use SWI mode iterator. (peephole2s for operations with memory outputs): Ditto. Do not check for stack checking probe. (probe_stack): Remove expander. Patch was bootstrapped and regression tested on x86_64-linux-gnu {,-m32}. Committed to mainline SVN. Uros.
