10 years ago[FastISel] Undo phi node updates when falling-back to SelectionDAG.

[FastISel] Undo phi node updates when falling-back to SelectionDAG.

The included test case would fail, because the MI PHI node would have two
operands from the same predecessor.

This problem occurs when a switch instruction couldn't be selected. This happens
always, because there is no default switch support for FastISel to begin with.

The problem was that FastISel would first add the operand to the PHI nodes and
then fall-back to SelectionDAG, which would then in turn add the same operands
to the PHI nodes again.

This fix removes these duplicate PHI node operands by reseting the
PHINodesToUpdate to its original state before FastISel tried to select the
instruction.

Chandler Carruth [Wed, 27 Aug 2014 11:22:16 +0000 (11:22 +0000)]
[SDAG] Re-instate r215611 with a fix to a pesky X86 DAG combine.

This combine is essentially combining target-specific nodes back into target
independent nodes that it "knows" will be combined yet again by a target
independent DAG combine into a different set of target-independent nodes that
are legal (not custom though!) and thus "ok". This seems... deeply flawed. The
crux of the problem is that we don't combine un-legalized shuffles that are
introduced by legalizing other operations, and thus we don't see a very
profitable combine opportunity. So the backend just forces the input to that
combine to re-appear.

However, for this to work, the conditions detected to re-form the unlegalized
nodes must be *exactly* right. Previously, failing this would have caused poor
code (if you're lucky) or a crasher when we failed to select instructions.
After r215611 we would fall back into the legalizer. In some cases, this just
"fixed" the crasher by produces bad code. But in the test case added it caused
the legalizer and the dag combiner to iterate forever.

The fix is to make the alignment checking in the x86 side of things match the
alignment checking in the generic DAG combine exactly. This isn't really a
satisfying or principled fix, but it at least make the code work as intended.
It also highlights that it would be nice to detect the availability of under
aligned loads for a given type rather than bailing on this optimization. I've
left a FIXME to document this.

Original commit message for r215611 which covers the rest of the chang:
  [SDAG] Fix a case where we would iteratively legalize a node during
  combining by replacing it with something else but not re-process the
  node afterward to remove it.

  In a truly remarkable stroke of bad luck, this would (in the test case
  attached) end up getting some other node combined into it without ever
  getting re-processed. By adding it back on to the worklist, in addition
  to deleting the dead nodes more quickly we also ensure that if it
  *stops* being dead for any reason it makes it back through the
  legalizer. Without this, the test case will end up failing during
  instruction selection due to an and node with a type we don't have an
  instruction pattern for.

It took many million runs of the shuffle fuzz tester to find this.

ArgPromotion: Don't touch variadic functions

Adding, removing, or changing non-pack parameters can change the ABI
classification of pack parameters. Clang and other frontends encode the
classification in the IR of the call site, but the callee side
determines it dynamically based on the number of registers consumed so
far. Changing the prototype affects the number of registers consumed
would break such code.

Dead argument elimination performs a similar task and already has a
similar check to avoid this problem.
