[Bug target/55642] [4.8 Regression] Invalid thumb code generated (thumb conditional instruction should be in IT block)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55642 Kyrill Tkachov kyrylo.tkachov at arm dot com changed: What|Removed |Added CC||kyrylo.tkachov at arm dot ||com --- Comment #2 from Kyrill Tkachov kyrylo.tkachov at arm dot com 2012-12-11 10:28:11 UTC --- Regression introduced with r193724. The abssi2 patterns in thumb2.md output two instructions but the enclosing it block thinks it's only one and therefore has the wrong number of t's (it instead of itt). Currently testing a patch to fix this. Thanks, Kyrill

Thanks. Diego. Hi Diego, As of today, the ICE has gone. The compilation test passes. But the execution test fails on qemu: FAIL: gcc.dg/sms-7.c execution test Should this be a separate issue then? Is there any other data I can provide that would be helpful? Thanks, Kyrill

[Bug testsuite/55230] UNSUPPORTED: g++.dg/mv1.C -std=gnu++11
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55230 Kyrill Tkachov kyrylo.tkachov at arm dot com changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||WONTFIX --- Comment #2 from Kyrill Tkachov kyrylo.tkachov at arm dot com 2012-11-12 14:06:50 UTC --- Ah ok, Since we don't have a g++.target directory, g++.dg does seem the most appropriate. I think though that if we end up adding a lot of tests like that in the future, it would be a good idea to create a g++.target directory to reduce the number of UNSUPPORTED complaints on other targets. Thanks, Kyrill
