Chandler Carruth [Tue, 19 Nov 2013 09:03:18 +0000 (09:03 +0000)]
Fix an issue where SROA computed different results based on the relative
order of slices of the alloca which have exactly the same size and other
properties. This was found by a perniciously unstable sort
implementation used to flush out buggy uses of the algorithm.

The fundamental idea is that findCommonType should return the best
common type it can find across all of the slices in the range. There
were two bugs here previously:

1) We would accept an integer type smaller than a byte-width multiple,
   and if there were different bit-width integer types, we would accept
   the first one. This caused an actual failure in the testcase updated
   here when the sort order changed.
2) If we found a bad combination of types or a non-load, non-store use
   before an integer typed load or store we would bail, but if we found
   the integere typed load or store, we would use it. The correct
   behavior is to always use an integer typed operation which covers the
   partition if one exists.

While a clever debugging sort algorithm found problem #1 in our existing
test cases, I have no useful test case ideas for #2. I spotted in by
inspection when looking at this code.

The problem is loops like:

  lbl:
    a &= 4;
    b--;

255 to get the exit count we overflow to zero.

Revert r194865 and r194874.

This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
  Base *foo = new Child();
  delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.

Debug Info Verifier: disable it by default.

Debug info verifier is part of the verifier which is a Function Pass.
Tot currently tries to pull all reachable debug info MDNodes in each function,
which is too time-consuming. The correct fix seems to be separating debug info
verification to its own module pass.

I will disable the debug info verifier until a correct fix is found.

time from 11s to 11m.

Debug Info Verifier: fix when to find debug info nodes and when to verify them.

We used to collect debug info MDNodes in doInitialization and verify them in
doFinalization. That is incorrect since MDNodes can be modified by passes run
between doInitialization and doFinalization.

To fix the problem, we handle debug info MDNodes that can be reached from a
function in runOnFunction (i.e we collect those nodes by calling processDeclare,
processValue and processLocation, and then verify them in runOnFunction).

We handle debug info MDNodes that can be reached from named metadata in
doFinalization. This is in line with how Verifier handles module-level data
(they are verified in doFinalization).
