[Freemint-discuss] Invalid FPU opcode used for 060

[Thorsten O. <ad...@th...>]

As recently found (see https://www.atari-forum.com/viewtopic.php?
t=43666&start=50) gcc sometimes produces FPU opcodes which are not valid for 
060 and have to be emulated:

$ cat bla.c

double x;

void test(void)
{
        x *= 9;
}

$ m68k-atari-mint-gcc -S -O2 -fomit-frame-pointer -m68060 -o - bla.c

_test:
        fdmove.d _x,%fp0
        fdmul.d #0x4022000000000000,%fp0
        fmove.d %fp0,_x
        rts

(immediate addressing has been removed for FPU instructions on 060).
As you can see this also happens when compiling for 060 *only*. IMHO this is a 
bug, since it is not a valid opcode for that architecture.

Do you think it is worth trying to fix this?
