[Bug c/36500] New: gcc ICEs when being passed -mfpu=neon

["koen at openembedded dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When crosscompiling for OMAP3 gcc will ICE if you use -mfpu=neon

No ICE: -march=armv7-a -mtune=cortex-a8 -mfpu=vfp -mfloat-abi=softfp
ICE: -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp

Testcase:
koen@lieve:/OE/angstrom-tmp/work$ cat helloworld.c 
#include <stdio.h>
int main(void)
{
        printf("Hello world!\n");       while(1);
        return 0;
}
koen@lieve:/OE/angstrom-tmp/work$ arm-angstrom-linux-gnueabi-gcc-4.3.1
helloworld.c -o helloworld -march=armv7-a -mtune=cortex-a8 -mfpu=neon
-mfloat-abi=softfp
helloworld.c:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Replace it with -mfpu=vfp:
koen@lieve:/OE/angstrom-tmp/work$ arm-angstrom-linux-gnueabi-gcc-4.3.1
helloworld.c -o helloworld -march=armv7-a -mtune=cortex-a8 -mfpu=vfp
-mfloat-abi=softfp
koen@lieve:/OE/angstrom-tmp/work$ file helloworld
helloworld: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux
2.6.14, dynamically linked (uses shared libs), not stripped
