Subject: [Bug tree-optimization/17531] New: [ivopts] ICE compiling gzip deflate.c
Date: Fri, 17 Sep 2004 02:54:00 -0000 [thread overview]
Message-ID: <20040917025408.17531.dje@gcc.gnu.org> (raw)
In SPEC CPU2000 164.gzip does
not build due to an ICE in emit_move_insn() whose backtrace leads to
ivopts. The same failure occurs with gzip-1.2.4a.
$ ./xgcc -B./ -O1 -fstrict-aliasing -S deflate.c
deflate.c: In function 'deflate_fast':
deflate.c:584: internal compiler error: in emit_move_insn, at expr.c:2485
$ ./xgcc -B./ -O1 -fstrict-aliasing -fno-ivopts -S deflate.c
$
Backtrace:
