Bug ID: 58814
Summary: [4.7/4.8/4.9 Regression] ICE with volatile and
attribute vector_size
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following valid code snippet triggers an ICE since GCC 4.7.0:
====================================================
volatile int i __attribute__((vector_size(8)));
void foo()
{
i += i;
}
====================================================
bug.cc: In function 'void foo()':
bug.cc:5:5: internal compiler error: in stabilize_expr, at cp/tree.c:3769
i += i;
