--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So on aarch64, the code for all three functions are almost the same:
foo(int, int):
sdiv w2, w0, w1
madd w1, w2, w1, w1
sub w0, w1, w0
ret
bar(int, int):
sdiv w2, w0, w1
madd w1, w2, w1, w1
sub w0, w1, w0
ret
tgt(int, int):
sdiv w2, w0, w1
msub w0, w2, w1, w0
sub w0, w1, w0
ret
MSVC can do the transformation.
