--- Comment #8 from Janis Johnson <janis at gcc dot gnu.org> 2012-07-31 15:56:12 UTC --- For some reason I couldn't apply the patch, but manually changed the tests to use { scan-assembler-times regexp 2 } instead of { scan assembler regexp }. Ramana, have you tried running the tests? They should pass but don't. I'll take a closer look at what scan-assembler-times and Tcl's regexp are doing.
