Can the and
immediate be larger than 5 bits? I'm not very familiar with Mips encodings.

Sorry, it can be larger than 5, it should be immZExt16
. I would submit again. Thanks!

I don't work on MIPS anymore but this looks correct to me.
One nit: I think it would be good to pre-commit the test with the existing codegen first and then have this patch show the codegen improvement.
Yes, this would be best. Thanks! |
You could commit the baseline test directly and then just update this pull request. |
1. Add MipsPat to optimize (andi (srl (truncate i64 $1), x), y) to (andi (truncate (dsrl i64 $1, x)), y). 2. Add MipsPat to optimize (ext (truncate i64 $1), x, y) to (truncate (dext i64 $1, x, y)). The assembly result is the same as gcc. Fix llvm#42826

OK, I submitted test #102278. Please help review, thanks! |
I've merged that other commit, once this one has been rebased I can go ahead and merge it. Thanks! |
Thanks, I have updated this pull request. |
