Summary: [4.6 Regression] ICE with FMA_EXPR in DEBUG stmts
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: debug
AssignedTo: jakub@gcc.gnu.org
ReportedBy: jakub@gcc.gnu.org
/* { dg-do compile } */
/* { dg-options "-O2 -g" } */
double
foo (double x, double y, double z)
{
double a = x * y + z;
double b = __builtin_fma (x, y, z);
double c = fma (x, y, z);
return x / y / z;
}
ICEs on targets where fma/__builtin_fma is transformed into FMA_EXPR.
The first problem is that FMA_EXPR is not handled in tree-ssa-operands.c, the
second issue is that it is not handled in expand_debug_expr.

Confirmed, can cause a bootstrap failure also (see
