[Bug target/28675] [4.1/4.2 regression] ICE in extract_insn, at recog.c:2084 (unrecognizable insn) [arm]
--- Comment #8 from tbm at cyrius dot com 2006-09-27 14:03 --- gcc/testsuite/gcc.dg/compat/scalar-return-4_y.c fails with this ICE. Do you know if this is the same or a different problem? This is on ARM old ABI, fails with 4.1 and 4.2. 4.0 works. -- tbm at cyrius dot com changed: What|Removed |Added CC||tbm at cyrius dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28675

--- Comment #5 from pbrook at gcc dot gnu dot org 2006-09-13 19:00 --- This is looking like a latent reload bug. I don't see anything in r105121 that could cause this bug. I can reproduce it on non-linux and non-eabi arm targets. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28675

--- Comment #4 from janis at gcc dot gnu dot org 2006-08-11 19:24 --- A regression hunt using an arm-ep93xx-linux-gnueabi cross compiler on powerpc-linux, with the testcase minimal.c, identified the following patch: http://gcc.gnu.org/viewcvs?view=revrev=105121 r105121 | kazu | 2005-10-08 18:17:20 + (Sat, 08 Oct 2005) This is a large merge from the csl-arm-branch to mainline. The test does not fail for a cross compiler built from revision 104998, the last revision on that branch before the merge, suggesting that his is a problem with the merge itself. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28675
