New Revision: 71777

URL: http://llvm.org/viewvc/llvm-project?rev=71777&view=rev
Log:
Merge in 71774:

Skip the asm prefix when storing the name in block info.
 - Otherwise we emit internal names with embedded '\01' characters,
   which confuses some tools.

 - Ideally all the code which wants to get a "display name" for the
   given function should follow one code path, but this should be a
   monotonic improvement for now.
