[PATCH] D155087: [CodeGen] Fix assertion failure caused by inline assembly

[Bryan Chan via Phabricator via llvm-commits]

bryanpkc added inline comments.


================
Comment at: llvm/test/CodeGen/X86/inline-asm-assertion.ll:3
+; RUN: not llc -O0 < %s 2>&1 | FileCheck %s
+; CHECK: error: inline assembly requires more registers than available
+
----------------
Suggestions:

1. Add a `CHECK` line to match the output assembly, e.g. `; CHECK: .size main, .Lfunc_end0-main`, to ensure that that the backend does not crash after register allocation.
1. Add a `RUN` line with `llc -O2` to ensure that `RegAllocGreedy` behaves the same way.
