InlineAsm and allocation to wrong register for indirect access
Hi,
I am seeing a case, in a private port, of an inline asm with indirect
memory references being allocated invalid registers (i.e. registers that
cannot be used on loads).
For example, the inline asm constraint is correct:
call void asm sideeffect "MOV $$r0, $0\0AMOV $$r0, $1\0A",
"*m,*m,~{r0}"(i16* @a, i16* %b) #1, !srcloc !1
but then $0 and $1 are allocated to registers
