Subject: optimization/8412: Code generation problem with -march=k6
Date: Thu, 31 Oct 2002 02:56:00 -0000 [thread overview]
Message-ID: <20021031104751.30825.qmail@sources.redhat.com> (raw)
>Number: 8412
>Category: optimization
>Synopsis: Code generation problem with -march=k6
>Confidential: no
>Severity: serious
>Priority: medium
>Responsible: unassigned
>State: open
>Class: ice-on-legal-code
>Submitter-Id: net

>Originator: alexander.puchmayr@jku.at
>Release: gcc version 3.2
>Organization:
>Environment:
i586
>Description:
The attached file (from xine-lib-0.9.13-r1), src/libfaad/syntax.i produces an ICE when compiling with -march=k6 and -funroll-loops. The file compiles fine with
-march=i586, athlon, athlon-xp, i686, pentium4, this it seems to be a k6 related problem.
Error-Message:
syntax.c: In function `section_data':
syntax.c:804: unrecognizable insn:
(insn 863 880 865 (set (reg:SI 280)
(zero_extend:SI (reg/v:QI 74))) -1 (nil)
(nil))
syntax.c:804: Internal compiler error in extract_insn, at recog.c:2148
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
>How-To-Repeat:
invoke gcc3-2 with:
gcc -march=k6 -O3 -funroll-loops -c syntax.i
>Fix:
Use i586 instead of k6
