dereferencable -> dereferenceable

LLVM — llvm/trunk/include/llvm/CodeGen MachineMemOperand.h, llvm/trunk/lib/CodeGen MachineInstr.cpp

[SelectionDAG] set dereferenceable flag when expanding memcpy/memmove

When SelectionDAG expands memcpy (or memmove) call into a sequence of load and store 
instructions, it disregards dereferenceable flag even the source pointer is known to be 
dereferenceable.
This results in an assertion failure if SelectionDAG commonizes a load instruction 
generated for memcpy with another load instruction for the source pointer.
This patch makes SelectionDAG to set the dereferenceable flag for the load instructions 
properly to avoid the assertion failure.

LLVM — llvm/trunk/tools/bugpoint bugpoint.cpp CMakeLists.txt

Ensure backends available in 'opt' are also available in 'bugpoint'

This patch links LLVM back-ends into bugpoint the same way they are already
available in 'opt' and 'clang'. This resolves an inconsistency that allowed the
use of LLVM backends in loadable modules that run in 'opt', but that would
prevent the debugging of these modules with bugpoint due to unavailable /
unresolved symbols.

For e.g. In D31859, Polly requires the NVPTX back-end.

[IR] Remove BinOp2_match and replace its usage with the more capable BinOpPred_match.

[IR][AssumptionCache] Add m_Shift and m_BitwiseLogic matchers to replace a couple

Summary:
m_CombineOr isn't very efficient. The code using it is also quite verbose.

This patch adds m_Shift and m_BitwiseLogic matchers to make the using code more concise 
and improve the match efficiency.

Remove a processFixupValue hack.

The intention of processFixupValue is not to redefine the semantics of
MCExpr. It is odd enough that a expression lowers to a PCRel MCExpr or
not depending on what it looks like. At least it is a local hack now.

I left a fix for anyone trying to figure out what producers should be
producing a different expression.

[InstCombine] Don't replace allocas with smaller globals

Summary:
InstCombine replaces large allocas with small globals consts causing buffer overflows
on valid code, see PR33372.

This fix permits this optimization only if the global is dereference for alloca size.

LLVM — llvm/trunk/include/llvm/MC MCAssembler.h MCAsmBackend.h, llvm/trunk/lib/MC MCAssembler.cpp

ARM: move some logic from processFixupValue to applyFixup.

processFixupValue is called on every relaxation iteration. applyFixup
is only called once at the very end. applyFixup is then the correct
place to do last minute changes and value checks.

While here, do proper range checks again for fixup_arm_thumb_bl. We
used to do it, but dropped because of thumb2. We now do it again, but
use the thumb2 range.

[ubsan] Improve diagnostics for return value checks (clang)

This patch makes ubsan's nonnull return value diagnostics more precise,
which makes the diagnostics more useful when there are multiple return
statements in a function. Example:

1 |__attribute__((returns_nonnull)) char *foo() {
2 |  if (...) {
3 |    return expr_which_might_evaluate_to_null();
4 |  } else {
5 |    return another_expr_which_might_evaluate_to_null();
6 |  }
7 |} // <- The current diagnostic always points here!

runtime error: Null returned from Line 7, Column 2!
With this patch, the diagnostic would point to either Line 3, Column 5
or Line 5, Column 5.

This is done by emitting source location metadata for each return
statement in a sanitized function. The runtime is passed a pointer to
the appropriate metadata so that it can prepare and deduplicate reports.

[LoopDeletion] NFC: Move phi node value setting into prepass
