Update of bug #48765 (project avr-libc):
Status: None => Need Info
_______________________________________________________
Follow-up Comment #1:
I'm not so sure. %C1 and %D1 are defined as bytes of __x, and %0 is __exp -
surely the compiler should keep those separate as they are separate variables
existing in the same scope?
I'm going to mark this Need Info unless someone else can correct me on this. I
can't see the potential issue here.
The only way I was able to force a collision was to rewrite my own version of
isfinite() with 'register unsigned char __exp asm("r27")' to force it to use a
colliding register. Otherwise, surely it should be required to keep them
separate while they are still valid in the scope?
