--- Comment #24 from Zdenek Sojka <zsojka at seznam dot cz> 2010-12-23 20:56:46 UTC --- Created attachment 22848 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22848 testcase failing in r168214 Thank you for fixing all the problem so far, but there seems to be further problem, this time with array of volatile floats and insane set of flags. I hope to find a more sane testcase... $ gcc -O -fprofile-generate -fgcse -fno-gcse-lm -fgcse-sm -fno-ivopts -fno-tree-loop-im -ftree-pre -funroll-loops -fno-web -fschedule-insns2 -fselective-scheduling2 -fsel-sched-pipelining pr45352_r168214.c pr45352_r168214.c: In function 'foo': pr45352_r168214.c:13:1: internal compiler error: in reset_sched_cycles_in_current_ebb, at sel-sched.c:7105 Please submit a full bug report, with preprocessed source if appropriate.
