Summary: ICE on several benchmarks after r196775.
Classification: Unclassified
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: [email protected]
ReportedBy: [email protected]
We got ICE on several benchmarks that can be reproduced on the simple
test-case:
typedef struct {
float a,b,c;
} S;
S * arr[100];
void bar (float *in[], int n)
{
int i;
for (i=0; i<n; i++)
(*in)[i] = -arr[i]->b;
}
and compile on x86 with following options:
-march=core-avx2 -O3
