Bug ID: 59133
Summary: [4.9 regression] ICE after r204219 on SPEC2006
435.gromacs.
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ysrumyan at gmail dot com
I attached a simple reproducer to compile with -march=core-avx2 -c -O3
-ffast-math options (-ffast-math is essential) and got the following ICE:
t.c: In function 'bar2':
t.c:39:1: internal compiler error: Max. number of generated reload insns per
insn is achieved (90)
}

Created attachment 31219
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31219&action=edit
test-case to reproduce
Need to be compiled with -m32 -march=core-avx2 -O3 -ffast-math options to
reproduce ICE.

It is worth noting that -m32 option is also essential for reproducing.

--- Comment #3 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
I've started to work on it. The problem is in that LRA has not enough code to
deal with creation of pseudos out of its scope. I guess the fix will be ready
next week on Wednesday as the patch will need a lot of testing.
