There were crashes (addrspace-memoperands.mir was only one of them) in MIR that had operands that came from before register classes were set. With these operands, creating a replacement vreg (for MIR-Canon's renaming) needs to use the vreg type rather than the RegisterClass which is not present. Differential Revision: https://reviews.llvm.org/D62543 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@362122 91177308-0d34-0410-b5e6-96231b3b80d8
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
