The ICE stopped occurring on trunk with r170984 (PR41490 fix). However that's a generic missed-optimization fix, so I suspect the bug is latent on trunk.

Unfortunately, on i686 host I was able to reproduce the ICE also with revisions 164134 and 164135 and so I assumed that Mikael made a mistake when he tracked the cause of the ICE to my commit in comment #3. When verifying that on an x86_64 host, I realized that the ICE indeed started happening with my commit but it re-appeared quickly with previous revisions when I added -fno-tree-sra to the command line options. Therefore I believe my patch did not cause any bug but uncovered some other issue elsewhere. In order to help at least a little, I did my own bisecting, this time with -fno-tree-sra, and to me it appears the ICE (still present on the 4.6 branch) is introduced by revision 163935: 2010-09-07 Bernd Schmidt ber...@codesourcery.com PR target/43137 * config/arm/iterators.md (qhs_zextenddi_cond, qhs_sextenddi_cond): New define_mode_attrs. * config/arm/arm.md (zero_extendsidi2, arm_zero_extendsidi2, arm_exxtendsidi2, arm_extendsidi2): Delete patterns.
