Implement simple register assignment for inline asms. This allows us to compile:
int %test(int %A, int %B) {
%C = call int asm "xyz $0, $1, $2", "=r,r,r"(int %A, int %B)
ret int %C
}
into:
(0x8906130, LLVM BB @0x8902220):
%r2 = OR4 %r3, %r3
%r3 = OR4 %r4, %r4
INLINEASM <es:xyz $0, $1, $2>, %r2<def>, %r2, %r3
%r3 = OR4 %r2, %r2
BLR
which asmprints as:
_test:
or r2, r3, r3
or r3, r4, r4
xyz $0, $1, $2 ;; need to print the operands now :)
or r3, r2, r2
blr
