Fix test case comment (NFC) llvm-svn: 256206
2015-12-22 06:26:49 +08:00
;; Check that PGO instrumented variables associated with linkonce odr
;; functions are placed in the same comdat section.
Final fix for PR 23499 and IR test case. This fixes a bit I forgot in r238335. In addition to the data record and the counter, we can also move the name of the counter to the comdat for the associated function. I'm also adding an IR test case to check that these three elements are placed in the proper comdat. llvm-svn: 238351

[PGO] Fix another comdat related issue for COFF The linker requires that a comdat section must be associated with a another comdat section that precedes it. This means the comdat section's name needs to use the profile name var's name. Patch tested by Johan Engelen. llvm-svn: 256220
