whitequark	a733290359	arch: bring back clobbers for input operands. This reverts a part of 365e40b. While it is not legal to clobber the output register, it is legal and necessary to do this for inputs, since we do not preserve them, and LLVM could have decided to reuse them. Thanks to @Amanieu for discovering this.	2016-08-31 14:17:54 -04:00

whitequark	2d8cefcabc	Do not simultaneously clobber registers passed into assembly. This is not actually legal (although the restriction is not documented anywhere), and is not caught by LLVM unless the codegen option -verify-machineinstrs is specified. This option is now used on Travis. While not legal, this does not seem to result in invalid output (although it creates an unnecessary spill); however, under extremely specific circumstances (e.g. when a register scavenger is run under severe pressure), this will result in a codegen crash, which is how I found it.	2016-08-30 12:20:34 -04:00
