>Description:
The following ICEs on sparc with 3.2, 3.2.1 and 3.3-cvs
This is a regression: 2.95.3 compiled this just fine.
The issue was originally reported by Niels Moeller as a mail
to gcc-bugs with a much longer testcase.
void f (void) {
unsigned char c;
__asm__ ("%0" :"=q" (c) );
}
>How-To-Repeat:
Compile the above code snippet.
>Fix:
Fix the code, the `q' constraint is undefined on sparc.
