I didn't think about this before, but as an alternative to duplicating everything in the other test, we could try just splitting out the libcalls that take or return pointers. That would mostly be the ones that return structs (frexp, modf). The rest should really just be duplicates (even though the test output would be different since the loads and stores to the stack would be different). WDYT?

Yes, it looks like all the tests that have loads and stores would need to be split out,. It looks like maybe 1/2 of the tests would need to duplicated?

I tried splitting out the ptr-size-specific tests and it turned out to be everything except @unordf/@unordt/@ordt.

Maybe you can figure out a better way? But maybe we just land this in the interim?

Oh right, the ones that return fp128 would have to be split out too. So that's more than half, maybe not worth it then.

SO this LGTM, but can you maybe add a comment to the top of this file and libcalls.ll that they should be kept in sync?
