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:
[EMAIL PROTECTED]:/OE/angstrom-tmp/work$ cat helloworld.c
#include stdio.h
int main(void)
{
printf(Hello world!\n); while(1);
return 0;
}

helloworld.c -o helloworld -march=armv7-a -mtune=cortex-a8 -mfpu=neon
-mfloat-abi=softfp
helloworld.c:1: internal compiler error: Segmentation fault

Replace it with -mfpu=vfp:
