--- Comment #1 from Oleg Endo <olegendo at gcc dot gnu.org> --- Created attachment 31265 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31265&action=edit Reduced test case > There is one weird case in CSiBE in > linux-2.4.23-pre3-testplatform/fs/iobuf.c (alloc_kiobuf_bhs) though, where > the individual decrement and test insns end up in different basic blocks and > only at the very end are emitted right next to each other without a label in > between. Attached is the reduced case of the above.
