[Bug middle-end/52375] [4.7 Regression] internal compiler error: in extract_insn, at recog.c:2123 at -O3 -mfpu=neon
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52375 --- Comment #8 from Richard Guenther rguenth at gcc dot gnu.org 2012-02-27 09:18:03 UTC --- (In reply to comment #7) If I bisect trunk configured as a cross to arm-linux-gnueabi, then the ICE starts with r181014: http://gcc.gnu.org/ml/gcc-cvs/2011-11/msg00300.html I still can't reproduce with the reduced test case. This just enables more vectorization.

See http://gcc.gnu.org/bugs.html for instructions. If it matters (I don't think it should...), this is an i686-pc-linux-gnu - arm-linux-androideabi crosscompiler.
