Vedant Kumar	563a747bd5	[opt] Introduce -strip-named-metadata ... This renames and generalizes -strip-module-flags to erase all named metadata from a module. This makes it easier to diff IR. llvm-svn: 333977	2018-06-05 00:56:08 +00:00
Vedant Kumar	0d0f43731c	[opt] Add a -strip-module-flags option ... The -strip-module-flags option strips llvm.module.flags metadata from a module at the beginning of the opt pipeline. This will be used to test whether the output of a pass is debug info (DI) invariant. E.g, after applying synthetic debug info to a test case, we'd like to strip out all DI-related metadata and check that the final IR is identical to a baseline file without any DI applied, to check that optimizations aren't inhibited by debug info. llvm-svn: 333860	2018-06-04 00:11:48 +00:00
