[ARM] - Fix lowering of shufflevectors in AArch32

Some shufflevectors are currently being incorrectly lowered in the AArch32
backend as the existing checks for detecting the NEON operations from the
shufflevector instruction expects the shuffle mask and the vector operands to be
of the same length.

This is not always the case as the mask may be twice as long as the operand;
here only the lower half of the shufflemask gets checked, so provided the lower
half of the shufflemask looks like a vector transpose (or even is just all -1

[Scalarizer] Fix potential for stale data in Scattered across invocations

Summary:
Scalarizer has two data structures that hold information about changes
to the function, Gathered and Scattered. These are cleared in finish()
at the end of runOnFunction() if finish() detects any changes to the
function.

However, finish() was checking for changes by only checking if
Gathered was non-empty. The function visitStore() only modifies
Scattered without touching Gathered. As a result, Scattered could have
ended up having stale data if Scalarizer only scalarized store
instructions. Since the data in Scattered is used during the execution
of the pass, this introduced dangling pointer errors.

The fix is to check whether both Scattered and Gathered are empty
before deciding what to do in finish(). This also fixes a problem
where the Function can be modified although the pass returns false.

9 years ago[Compiler-RT] Remove dependency on libgcc_s/eh
Renato Golin [Thu, 23 Jul 2015 17:24:41 +0000 (17:24 +0000)]
[Compiler-RT] Remove dependency on libgcc_s/eh

Currently, for --rtlib=compiler-rt on GNU systems, we're assuming
that one has libgcc_s and libgcc_eh as low-level libraries, which
when used in conjunction with -lunwind or -lc++abi, breaks that
assumption.

My original fix was wrong, and this patch reverts it to prepare for
a new flag to choose the unwinder/C++ libraries. For the time being,
people can use "-lgcc_s -lgcc_eh" or "-lunwind -lc++abi" or any
combination they need explicitly.

9 years agoRemoved redundant alias checks generated during run time.
Johannes Doerfert [Thu, 23 Jul 2015 17:04:54 +0000 (17:04 +0000)]
Removed redundant alias checks generated during run time.

  As specified in PR23888, run-time alias check generation is expensive
  in terms of compile-time. This reduces the compile time by computing
  minimal/maximal access only once for each base pointer

A similar patch will be upstreamed to ISL. We commit this ahead of time to
unblock people that are annoyed the permanent diffs we see in git.
