r227148 added test CommandLineTest.HideUnrelatedOptionsMulti which repeatedly
outputs two following lines:
-tool: CommandLine Error: Option 'test-option-1' registered more than once!
-tool: CommandLine Error: Option 'test-option-2' registered more than once!

divergent formatting issues. This should prevent any format-only diffs
from sneaking into subsequent changes to port TTI to the new pass
manager.

object that manages a single run of this pass.
This was already essentially how it worked. Within the run function, it
would point members at *stack local* allocations that were only live for
a single run. Instead, it seems much cleaner to have a utility object
whose lifetime is clearly bounded by the run of the pass over the
function and can use member variables in a more direct way.
This also makes it easy to plumb the analyses used into it from the pass
and will make it re-usable with the new pass manager.
No functionality changed here, its just a refactoring.

Modifying Darwin/interception-in-shared-lib-test.cc and suppressions-library.cc

This was causing problems on clang 602 branches that use MemoryObjects to as the container for opcode bytes instead of a plain array of bytes. So we were asking for 3 bytes to be disassembled at address 0xffffffffffffffff which would cause an unsigned overflow and cause the MemoryObject to refuse to read anymore bytes.

These tests check that the combination of 227110 (cross block query inst) and 227112 (volatile load semantics) work together properly to allow PRE in cases where a loop contains a volatile access.

For ordered, unordered, equal and not-equal tests, packed float and double comparison instructions can be safely commuted without affecting the results. This patch checks the comparison mode of the (v)cmpps + (v)cmppd instructions and commutes the result if it can.

This is especially useful for the UTF8 -> UTF16 direction, since
there is no equivalent of llvm::SmallString<> for wide characters.
This means that anyone who wants a null terminated string is forced
to manually push and pop their own null terminator.

Patch to allow (v)pclmulqdq to be commuted - swaps the src registers and inverts the immediate (low/high) src mask.

Need a new API for clang-modernize that allows specifying a list of option categories to remain visible. This will allow clang-modernize to move off getRegisteredOptions.

The backend won't run LowerExpect on -O0. In a debug LTO build, this results in llvm.expect intrinsics being in the LTO IR which doesn't know how to optimize them.

Time to link lld using lld improved from 5.7s to 5.4s on Windows.
It's not a significant improvement but not bad for one-line change.
This patch includes a bug fix for Parallel.h as the original code
uses operator< instead of a compare function there.

- Rename mmx-builtins to mmx-intrinsics to match other intrinsic test naming.
- Remove tests that duplicate functionality from mmx-intrinsics.ll.
- Move arith related tests to mmx-arith.ll.
- MMX related shuffle goes to vector-shuffle-mmx.ll.

We appear to use 3.5.0 in the directory structure now. That's probably
unnecessary. We should probably let the micro releases update the docs
for the same minor version.

An unreachable default destination can be exploited by other optimizations and
allows for more efficient lowering. Both the SDag switch lowering and
LowerSwitch can exploit unreachable defaults.
Also make TurnSwitchRangeICmp handle switches with unreachable default.
This is kind of separate change, but it cannot be tested without the change
above, and I don't want to land the change above without this since that would
regress other tests.

Instead of creating a pattern like "(p && a) || ((!p) && b)",
just expand the i8 operands to i32 and perform the selp on them.

This can also be used instead of the WindowsSupport.h ConvertUTF8ToUTF16
helpers, but that will require massaging some character types. The
Windows support routines want wchar_t output, but wchar_t is often 32
bits on non-Windows OSs.

Without this overload, attempts to edit the value of a variable with synthetic children enabled would change the value inside the synthetic ValueObject, but not propagate the changes to the underlying storage, hence resulting in no write for any meaningful purpose

Essentially DataLayout is global and affects the layout of ABI

look through the typedef (and any other sugar). We only use the
