------- Comment #9 from hubicka at gcc dot gnu dot org 2007-02-14 01:24 ------- Hi, the reason is -msse3 that is supposed to be at both invocations. -msse3 enables the SSE builtins that do change declarations UIDs that in turn changes function names: < ;; Function ddx (ddx.1401) --- > ;; Function ddx (ddx.1390) so profiles can't match. While it is possible to ignore the SSA names, I don't think there is actual need to mess with this - the use of different swtiches that do affect input language clearly can't be much accepted in between train and compilation run (I am hoping that optimization switches like -funroll-loops will run, but for language features, like SSE is we will get different divergences anyway)
The other problem was fixed, so I am closing the PR. Honza -- hubicka at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution| |FIXED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30650
