Bug #: 50307
Summary: SSA checking ICE when building Linux kernel
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: ice-checking
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: uweigand@gcc.gnu.org
Created attachment 25206
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25206
Reduced test case
When building the attached test case (reduced from Linux kernel code) with -O2
(tested on i386 and arm), I'm getting the following ICE:
vsprintf.i: In function ‘vscnprintf’:
vsprintf.i:5:1: error: number of operands and imm-links don’t agree in
statement
# .MEM_26 = VDEF <.MEM_17>
args = args_7(D);
vsprintf.i:5:1: internal compiler error: verify_ssa failed
Seems to be related to re-inlining and outlined part of the original function
...

I think it's another dup of that other bug.

I've confirmed that this is a regression introduced by rev. 178386
http://gcc.gnu.org/ml/gcc-cvs/2011-08/msg01405.html
So it does seem like this is another duplicate of PR 50287 / PR 50295.
