[PATCH] D24133: [ARM] Lower UDIV+UREM to UDIV+MLS (and the same for SREM)

[Pablo Barrio via llvm-commits]

pbarrio updated this revision to Diff 70377.
pbarrio added a comment.

Improved testing:

- New signed remainder test.
- New sdiv + srem test.
- Registers are given as regular expressions.

All tests merge to udiv/sdiv + mls.

I am not sure about adding a div+div+mod test, though. I have checked that
two identical divs + remainder merge just fine. However, is that an IR that
we can typically get? I would expect the two divs to be merged before getting
to the back-end.
