Bug ID: 89210
Summary: [9 Regression] ICE tree check: expected integer_cst,
have real_cst in to_wide, at tree.h:5600
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Changed between 20190106 and 20190113 on x86_64-pc-linux-gnu :
$ cat z1.c
typedef int v4si __attribute__((vector_size (4 * sizeof (int))));
typedef double v4df __attribute__((vector_size (4 * sizeof (double))));
void f (v4df *x)
{
v4si a = { 1, 2, 3, 4 };
*x = __builtin_convertvector (a, v4df);
}
$ gcc-9-20190203 -c z1.c -O0
$ gcc-9-20190203 -c z1.c -O2
during RTL pass: expand
z1.c: In function 'f':
z1.c:6:6: internal compiler error: tree check: expected integer_cst, have
real_cst in to_wide, at tree.h:5600
6 | *x = __builtin_convertvector (a, v4df);
