Hello,
The following piece of code cause an ICE to happen.
typedef struct {
unsigned long maskbits:20;
char extra;
} MYSTRUCT;
MYSTRUCT mys = {0};
void test_ice(void)
{
unisgned long lvar = 0x0f;
mys.maskbits = lvar; // <<== ICE here
}
kees:$ msp430-gcc -mmcu=msp430f449 -c mspgcc_ice.c
mspgcc_ice.c: In function 'test_ice':
mspgcc_ice.c:13:15: internal compiler error: in convert_move, at expr.c:437

smaller bitfields work well. I don't know if later mspgcc versions
does ICE here too.
