--- Comment #37 from Oleg Endo <olegendo at gcc dot gnu.org> 2012-05-07 20:50:31 UTC --- Created attachment 27336 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27336 Supplementary patch As of rev 187217, the pr51244-1.c target testcase fails at least for m4*. The attached patch adds some 'branch_true' and 'branch_false' subreg variants which combine tries to use. This seems to fix the problem. I still would like to know whether there is a better way of handling the little / big endian subreg offsets in the patterns without doing copy-pasta.
