Synopsis: Internal compiler error in gen_split_1231
State-Changed-From-To: open->analyzed
State-Changed-By: reichelt
State-Changed-When: Tue Nov 12 14:57:50 2002
State-Changed-Why:
Confirmed.
gcc 3.1 and mainline are not affected, but gcc 3.2 and the
3.2.1 prerelease produce an ICE.
Here's a shorter example that triggers the bug (just compile with
gcc -march=pentium3 -O -ffast-math -funroll-loops -c)
-------------------------snip here-----------------------
float foo (float *a)
{
int i, j;
float x=a[j=i-1], y;
for ( j=i; --j>=0; )
if( (y=a[j]) > x )
x = y;
return x;
}
-------------------------snip here-----------------------
Since the bug is a regression on the branch, I rate the PR "high priority".
