Fix another crasher in SROA, reported by Joel.

build fast lookup tables to locate a particular partition use from an
operand of a PHI or select. This is (obviously in hind sight)
incompatible with erasing elements from the array. Really, we don't want
to erase anyways. It is expensive, and a rare operation. Instead, simply
weaken the contract of the PartitionUse structure to allow null Use
pointers to represent dead uses. Now we can clear out the pointer to
mark things as dead, and all it requires is adding some 'continue'
checks to the various loops.

huge. I think this one I can get a nice test case for though, as it was

12 years agoRefactor the PartitionUse structure to actually use the Use* instead of
Chandler Carruth [Mon, 1 Oct 2012 01:49:22 +0000 (01:49 +0000)]
Refactor the PartitionUse structure to actually use the Use* instead of
a pair of instructions, one for the used pointer and the second for the
user. This simplifies the representation and also makes it more dense.

This was noticed because of the miscompile in PR13926. In that case, we
were running up against a fundamental "bad idea" in the speculation of
PHI and select instructions: the speculation and rewriting are
interleaved, which requires phi speculation to also perform load
rewriting! This is bad, and causes us to miss opportunities to do (for
example) vector rewriting only exposed after PHI speculation, etc etc.
It also, in the old system, required us to insert *new* load uses into
the current partition's use list, which would then be ignored during
rewriting because we had already extracted an end iterator for the use
list. The appending behavior (and much of the other oddities) stem from
the strange de-duplication strategy in the PartitionUse builder.
Amusingly, all this went without notice for so long because it could
only be triggered by having *different* GEPs into the same partition of
the same alloca, where both different GEPs were operands of a single
PHI, and where the GEP which was not encountered first also had multiple
uses within that same PHI node... Hence the insane steps required to
reproduce.

So, step one in fixing this fundamental bad idea is to make the
PartitionUse actually contain a Use*, and to make the builder do proper
deduplication instead of funky de-duplication. This is enough to remove
the appending behavior, and fix the miscompile in PR13926, but there is
more work to be done here. Subsequent commits will lift the speculation
into its own visitor. It'll be a useful step toward potentially
extracting all of the speculation logic into a generic utility
transform.

The existing PHI test case for repeated operands has been made more
extreme to catch even these issues. This test case, run through the old
pass, will exactly reproduce the miscompile from PR13926. ;] We were so
