Bug #: 50576
Summary: Recent vector comparison changes cause an ICE
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mgretton@sourceware.org
CC: artyom.shinkaroff@gmail.com,
richard.guenther@gmail.com
Host: x86_64-linux-gnu
Target: arm-none-eabi
Compiling the following (cut down from the
gcc.c-torture/execute/vector-compare-1.c test case):
/* try.c. */
int
main (int argc, char *argv[])
{
__attribute__ ((vector_size ((2) * sizeof (double)))) double d0;
__attribute__ ((vector_size ((2) * sizeof (double)))) double d1;
__attribute__ ((vector_size ((2) * sizeof (long long)))) long long idres;
{
idres = (d0 > d1);
}
}
/* end of try.c. */
with:
arm-none-eabi-gcc -mfpu=neon -mfloat-abi=softfp -mcpu=cortex-a9 -c try.c
Gives:
try.c: In function 'main':
try.c:3:1: error: invalid vector comparison resulting type
vector(2) long long int
idres = d0 > d1;
try.c:3:1: internal compiler error: verify_gimple failed
This was tested with trunk r179378.
The issue was introduced by this patch
(http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01088.html - checked in as
r179342), and has not been fixed by Richard Guenther's follow on patch
(http://gcc.gnu.org/ml/gcc-patches/2011-09/msg01933.html).

is sizeof(long long) == sizeof (double)?

Yes - sizeof(long long) and sizeof(double) are both 8.
