Bug #: 55122
Summary: ICE: maximum number of LRA constraint passes is
achieved (15)
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: antoine.balestrat@gmail.com
Hello !
I'm using GCC 4.8.0 as of 20121029 (r192944) at -O3 and in 32 bit mode :
$ cat lra.c
int i, a;
unsigned long long b;
void f(void)
{
for(i = 0; i < 15; i++)
b *= b;
b *= a ? 0 : b;
}
$ xgcc -w -O3 -m32 lra.c
lra.c: In function ‘f’:
lra.c:10:1: internal compiler error: Maximum number of LRA constraint passes is
achieved (15)
}
