rG564d85e090af: The maximal representable alignment in LLVM IR is 1GiB, not 512MiB
Summary

In IR bitcode, the alignment is stored log2, biased by one (to represent 'default' alignment),
in 5 bits (would one/two extra bits cause the sky to fall?).
But that means that the maximal alignment exponent is (1<<5)-2, which is 30, not 29.
And indeed, alignment of 1073741824 rountrips IR serialization-deserialization.

While this doesn't seem all that important, this doubles the maximal supported alignment
from 512MiB to 1GiB, and there's actually one noticeable use-case for that;
On X86, the huge pages can have sizes of 2MiB and 1GiB (!).

So while this doesn't add support for truly huge alignments,
i think this adds zero-cost support for a not-trivially-dismissable case.

I don't believe we need any upgrade infrastructure,
and since we don't explicitly record the IR version, we don't need to bump one.

Wild speculation. This may be a historical artifact of LoadInst and StoreInst having their getAlignment() function written like this when this limit was created

unsigned getAlignment() const {
  return (1 << (getSubclassDataFromInstruction() >> 1)) >> 1;
}

Because "1" is signed int the left shift produced a signed int. The final right shift would be an arithmetic shift. So if the alignment was 1 << 30, the subclass data would be 31, the shift would produce INT_MIN, and the arithmetic right shift would produce 0xc0000000 which would be incorrect.

AllocaInst used 1U instead of 1 so would have been immune.

Could use some MIR tests to make sure that parser doesn't explode

Should use -run-pass=none, and go in test/CodeGen/MIR/X86

6–16 ↗(On Diff #368583)

Don't need the IR section

31 ↗(On Diff #368583)

Don't need the IR reference, can also test basealign

@arsenm i do not understand how i can avoid having IR there, but addressed other nits. thanks for taking a look!

lebedev.ri updated this revision to Diff 368722.Aug 25 2021, 2:15 PM

Address rest of nits.

Seems reasonable to me.

@arsenm are you happy with the test coverage here?

That does seem plausible :)

Add -march=x86-64 that i forgot :/

Thanks everyone!
I don't expect that there will be any further feedback, so i plan on landing this tomorrow, unless there is further feedback before then.
