I am working on making FileCheck stricter (in D54769 and D53710) so that it issues diagnostics when there's something wrong with tests. This is a cleanup for dangling prefixes in the ARM codegen tests, e.g.: --check-prefixes=A,B where A occurs in the check file, but B doesn't. This can be innocent if A does all the required checking, but can also be a bug in that test if it results in the test actually not checking anything (if A for example only checks a common label). Test CodeGen/ARM/smml.ll is such an example. Differential Revision: https://reviews.llvm.org/D54842 llvm-svn: 347487
