Don't add DBG_VALUE instructions for static allocas in dbg.declare

Summary:
An llvm.dbg.declare of a static alloca is always added to the
MachineFunction dbg variable map, so these values are entirely
redundant. They survive all the way through codegen to be ignored by

change. Despite my best efforts, I haven't been able to rewrite the test
case using dbg.value. I'm not too concerned about the lost coverage
because these were reduced from the test-suite, which we still run.

Zachary Turner [Mon, 8 May 2017 18:38:43 +0000 (18:38 +0000)]
[CodeView] Add support for random access type visitors.

Previously type visitation was done strictly sequentially, and
TypeIndexes were computed by incrementing the TypeIndex of the
last visited record.  This works fine for situations like dumping,
but not when you want to visit types in random order.  For example,
in a debug session someone might lookup a symbol by name, find that
it has TypeIndex 10,000 and then want to go straight to TypeIndex
10,000.

In order to make this work, the visitation framework needs a mode
where it can plumb TypeIndices through the callback pipeline.  This
patch adds such a mode.  In doing so, it is necessary to provide
an alternative implementation of TypeDatabase that supports random
access, so that is done as well.

Nothing actually uses these random access capabilities yet, but
this will be done in subsequent patches.

[ValueTracking] Introduce a version of computeKnownBits that returns a KnownBits struct. Begin using it to replace internal usages of ComputeSignBit

This introduces a new interface for computeKnownBits that returns the KnownBits object instead of requiring it to be pre-constructed and passed in by reference.

This is a much more convenient interface as it doesn't require the caller to figure out the BitWidth to pre-construct the object. It's so convenient that I believe we can use this interface to remove the special ComputeSignBit flavor of computeKnownBits.

As a step towards that idea, this patch replaces all of the internal usages of ComputeSignBit with this new interface. As you can see from the patch there were a couple places where we called ComputeSignBit which really called computeKnownBits, and then called computeKnownBits again directly. I've reduced those places to only making one call to computeKnownBits. I bet there are probably external users that do it too.

A future patch will update the external users and remove the ComputeSignBit interface. I'll also working on moving more locations to the KnownBits returning interface for computeKnownBits.

[Lit] Fix to prevent creation of "%SystemDrive%" directory on Windows.

This patch propogates the environment variable SYSTEMDRIVE on Windows when
running the unit tests. This prevents the creation of a directory named
"%SystemDrive%" when running the unit tests from FileSystemTest that use the
function llvm::sys::fs::remove_directories which in turn uses SHFileOperationW.
It is within SHFileOperationW that this environment variable may be used and if
undefined causes the creation of a "%SystemDrive%" directory in the current

Dean Michael Berris [Mon, 8 May 2017 05:45:21 +0000 (05:45 +0000)]
[XRay] Custom event logging intrinsic

This patch introduces an LLVM intrinsic and a target opcode for custom event
logging in XRay. Initially, its use case will be to allow users of XRay to log
some type of string ("poor man's printf"). The target opcode compiles to a noop
sled large enough to enable calling through to a runtime-determined relative
function call. At runtime, when X-Ray is enabled, the sled is replaced by
compiler-rt with a trampoline to the logic for creating the custom log entries.

Future patches will implement the compiler-rt parts and clang-side support for
emitting the IR corresponding to this intrinsic.

aligned slabs starting at 0x1000. Automatically remapping sections by default is

also preserve any mappings made by RuntimeDyld itself. Preserving RuntimeDyld's
automatic mappings allows us to write test cases to verify that these automatic

[Analysis] Print out unreachable loops

Summary:
When writing a loop pass I made a mistake and hit the assertion
"Unreachable block in loop". Later, I hit an assertion when I called
`BasicBlock::eraseFromParent()` incorrectly: "Use still stuck around
after Def is destroyed". This latter assertion, however, printed out
exactly which value is being deleted and what uses remain, which helped
me debug the issue.

To help people debugging their loop passes in the future, print out
exactly which basic block is unreachable in a loop.

[LazyValueInfo] Avoid unnecessary copies of ConstantRanges

Summary:
ConstantRange contains two APInts which can allocate memory if their width is larger than 64-bits. So we shouldn't copy it when we can avoid it.

This changes LVILatticeVal::getConstantRange() to return its internal ConstantRange by reference. This allows many places that just need a ConstantRange reference to avoid making a copy.

Several places now capture the return value of getConstantRange() by reference so they can call methods on it that don't need a new object.

Lastly it adds std::move in one place to capture to move a local ConstantRange into an LVILatticeVal.
