For this code:
unsigned foo(unsigned a)
{
unsigned l;
l = (a >= (~0u - 512) ? (~0u - 512) : a);
return l;
}
At any optimization level, including -O0, -O1 and -O2, you get
(at varying lines, of course):
x.s: Assembler messages:
x.s:14: Error: Immediate value not in 8 bit range: -513
The offending asm is:
bound.b -513,$r9
where the -513 operand is clearly not in the range (signed+unsigned) -128..255.
I can trace this back to (a modified version of) gcc-3.2.
