With this patch, this is not done for short optional branches. A short
optional branch is a branch containing a single block with an
instruction count below a certain threshold (defaulting to 3). Still

Outlining a short branch can't significantly improve code locality. It

Verifier: Remove the separate DebugInfoVerifier class

Remove the separate `DebugInfoVerifier` class, as a partial step toward
better integrating debug info verification with the `Verifier`.

Right now, verification of debug info is kind of a mess.

  - There are `DIDescriptor::Verify()` checks live in `DebugInfo.cpp`.
    These return `bool`, and there's no way to see (except by opening a
    debugger) why they fail.
  - We rely on `DebugInfoFinder` to traverse the debug info graph and
    dig up nodes.  However, the regular `Verifier` visits many of these
    nodes when it calls into debug info intrinsic operands.  Visiting
    twice and running different checks is kind of absurd.
  - Moreover, `DebugInfoFinder` asserts on failed type resolution -- the
    verifier should never assert!

By integrating the two verifiers, I'm aiming at solving these problems
(work to be done, obviously).  Verification can be localized to the
`Verifier`; we can use a naive `MDNode` operand traversal to find all
the nodes; we can verify type references instead of asserting on

There are `assert()`s sprinkled throughout the optimizer and dwarf
backend on `DIDescriptor::Verify()` checks.  This is a hangover from
when the debug info verifier was off, so I plan to remove them as I go
(once I confirm that the checks are done at verification time).

Note: to keep the behaviour of only running the debug info verifier when
-verify succeeds, I've added an `EverBroken` flag.  Once the
`DebugInfoFinder` assertions are gone and the two traversals have been
merged, I expect to be able to remove this.

7 years ago[InstCombine] Don't fold a GEP into itself through a PHI node
Daniel Jasper [Thu, 19 Mar 2015 11:05:08 +0000 (11:05 +0000)]
[InstCombine] Don't fold a GEP into itself through a PHI node

This can only occur (I think) through the back-edge of the loop.

However, folding a GEP into itself means that the value of the previous
iteration needs to be stored in the meantime, thus requiring an
additional register variable to be live, but not actually achieving
anything (the gep still needs to be executed once per loop iteration).

The attached test case is derived from:
  typedef unsigned uint32;
  typedef unsigned char uint8;
  inline uint8 *f(uint32 value, uint8 *target) {
    while (value >= 0x80) {
      value >>= 7;
    return target;
  uint8 *g(uint32 b, uint8 *target) {
    target = f(b, f(42, target));
    return target;

What happens is that the GEP stored in incptr2 is folded into itself
through the loop's back-edge and the phi-node stored in loopptr,
effectively incrementing the ptr by "2" in each iteration instead of "1".

In this case, it is actually increasing the number of GEPs required as
the GEP before the loop can't be folded away anymore. For comparison:
