<pre>This patch: <a href="https://reviews.llvm.org/D41330">https://reviews.llvm.org/D41330</a> seems to break when building the
test suite with -verify-machineinstrs.
Failed on Green Dragon here:
<a href="http://green.lab.llvm.org/green/job/test-suite-verify-machineinstrs-x86_64h-O3/1522/">http://green.lab.llvm.org/green/job/test-suite-verify-machineinstrs-x86_64h-O3/1522/</a>
There are many failures, but here is an example:
*** Bad machine code: Using a killed virtual register ***
- function:
_Z77FftConvolve128x128xCZHalide_x86_64_linux_c_plus_plus_name_mangling_no_runtimeP15halide_buffer_tS0_S0_
- basic block: %bb.32 true_bb (0x7fcc7812ee60)
- instruction: MOV64mr killed %487:gr64, 1, $noreg, 40, $noreg, %4569:gr64 ::
(store 8 into %ir.185 + 8, align 4)
- operand 0: killed %487:gr64
