------- Comment #14 from ubizjak at gmail dot com 2010-01-06 10:43 ------- This bug can be now reproduced with a crosscompiler to alpha-linux-gnu with soon to be attached preprocessed source of tree-ssa-loop-im.i (please note noinline attributes at determine_max_movement and add_dependency).
The problem is that stage1 (or cross-) compiler miscompiles determine_max_movement from tree-ssa-loop-im.c, where cse2 rtl pass removes whole lot of code when -O2 is used. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42511
