Jim Ingham 22eeb7227c The SetStopInfo from a Mach Exception was setting the stop
reason to None when we stop due to a trace, then noticed that
we were on a breakpoint that was not valid for the current thread.
That should actually have set it back to trace.

This was pr26441 (<rdar://problem/24470203>)

Reid Kleckner 45b6159ed3 Minor performance tweaks to llvm-tblgen (and a few that might be a good idea)
Summary:
This patch adds a reserve call to an expensive function
(`llvm::LoadIntrinsics`), and may fix a few other low hanging
performance fruit (I've put them in comments for now, so we can
discuss).

**Motivation:**

As I'm sure other developers do, when I build LLVM, I build the entire
project with the same config (`Debug`, `MinSizeRel`, `Release`, or
`RelWithDebInfo`). However, the `Debug` config also builds llvm-tblgen
in `Debug` mode. Later build steps that run llvm-tblgen then can
actually be the slowest steps in the entire build. Nobody likes slow
builds.

Duncan P. N. Exon Smith f42ef3efca re.results.form: Format out-of-range subexpression references as null
Rather than crashing in match_results::format() when a reference to a
marked subexpression is out of range, format the subexpression as empty
(i.e., replace it with an empty string).  Note that
match_results::operator[]() has a range-check and returns a null match
in this case, so this just re-uses that logic.

Zachary Turner 62d3a6570a Move some android platform functions to lldbplatformutil.
My eventual goal is to move all of the test decorators to their
own module such as `decorators.py`.  But some of the decorators
use existing functions in `lldbtest.py` and conceptually the
functions are probably more appropriately placed in lldbplatformutil.
Moreover, lldbtest.py is a huge file with a ton of random utility
functions scattered around, so this patch also workds toward the
goal of reducing the footprint of this one module to a more
reasonable size.

So this patch moves some of them over to lldbplatformutil with the
eventual goal of moving decorators over to their own module.

Quentin Colombet 7ec03dc7f8 [InstCombine] Revert r238452: Fold IntToPtr and PtrToInt into preceding loads.
According to git bisect, this is the root cause of a miscompile for Regex in
libLLVMSupport. I am still working on reducing a test case.
The actual bug may be elsewhere and this commit just exposed it.

Anyway, at the moment, to reproduce, follow these steps:
1. Build clang and libLTO in release mode.
2. Create a new build directory <stage2> and cd into it.
3. Use clang and libLTO from #1 to build llvm-extract in Release mode + asserts
   using -O2 -flto
4. Run llvm-extract  -ralias '.*bar' -S test/Other/extract-alias.ll

Result:
program doesn't contain global named '.*bar'!

Expected result:
@a0a0bar = alias void ()* @bar
@a0bar = alias void ()* @bar

declare void @bar()

Note: In step #3, if you don't use lto or asserts, the miscompile disappears.

Wei Mi ed133978a0 [SCEV] Try to reuse existing value during SCEV expansion
Current SCEV expansion will expand SCEV as a sequence of operations
and doesn't utilize the value already existed. This will introduce
redundent computation which may not be cleaned up throughly by
following optimizations.

This patch introduces an ExprValueMap which is a map from SCEV to the
set of equal values with the same SCEV. When a SCEV is expanded, the
set of values is checked and reused whenever possible before generating
a sequence of operations.

James Molloy 6e518a3b50 [DemandedBits] Revert r249687 due to PR26071
This regresses a test in LoopVectorize, so I'll need to go away and think about how to solve this in a way that isn't broken.

From the writeup in PR26071:

What's happening is that ComputeKnownZeroes is telling us that all bits except the LSB are zero. We're then deciding that only the LSB needs to be demanded from the icmp's inputs.

This is where we're wrong - we're assuming that after simplification the bits that were known zero will continue to be known zero. But they're not - during trivialization the upper bits get changed (because an XOR isn't shrunk), so the icmp fails.

The fault is in demandedbits - its contract does clearly state that a non-demanded bit may either be zero or one.

Runtimes should be able to pass custom compilation options to the JIT for their stack frame. This patch adds a custom expression options member class to LanguageOptions, and modifies the clang expression evaluator to check the current runtime for those options. If those options are available on the runtime, they are passed to the clang compiler.

Dylan McKay bff960a926 [TableGen] Add 'register alternative name matching' support
Summary:
This adds a new attribute which targets can set in TableGen which causes a function to be generated which matches register alternative names. This is very similar to `ShouldEmitMatchRegisterName`, except it works on alt names.

This patch is currently used by the out of tree part of the AVR backend. It reduces code duplication greatly, and has the effect that you do not need to hardcode altname to register mappings in C++.

It will not work on targets which have registers which share the same aliases.
