The MachO back-end needs to emit the garbage collection flags specified in the
module flags. This is a WIP, so the front-end hasn't been modified to emit these
flags just yet. Documentation and front-end switching to occur soon.

that are greater than the vector element type. For example BUILD_VECTOR
of type <1 x i1> with a constant i8 operand.
This patch fixes the assertion.

Move old movl vector_shuffle patterns. Not needed anymore since vector_shuffles shouldn't reach isel.

Rename getExceptionAddressRegister() to getExceptionPointerRegister() for consistency with setExceptionPointerRegister(...).

This folds a simple loop tail into a loop latch. It covers the common (in fortran) case of postincrement loops. It's a "free" way to expose this type of loop to downstream loop optimizations that bail out on non-canonical loops (getLoopLatch is a heavily used check).

marking them as "live-in" into a BB ruins some invariants that the back-end
tries to maintain.

The scheduler will sometimes check the implicit-def list on instructions
to properly handle pre-colored DAG edges.

Also check any register mask operands for physreg clobbers.

escape. This fixes rdar://10803830.

Clang patch (flags) will follow shortly.
The run-time library will also follow, but not immediately.

v2f16 is a floating point type.  Add symbolic floating point type ranges to prevent this kind of issue in the future.

This is useful for clients that want to maintain compatibility
across multiple releases of LLVM. Currently users like Klee and
Mesa all have to roll their own 'parse llvm-config --version
output and generate defines' solution.

Also reuse the new macros so that version information is less
redundant/likely to fall out of sync again in the future.

Fix a bug in DAGCombine for the optimization of BUILD_VECTOR. We cant generate a shuffle node from two vectors of different types.

- Use unsigned literals when the desired result is unsigned. This mostly allows unsigned/signed mismatch warnings to be less noisy even if they aren't on by default.
- Remove misplaced llvm_unreachable.
- Add static to a declaration of a function on MSVC x86 only.
- Change some instances of calling a static function through a variable to simply calling that function while removing the unused variable.

llvm-svn: 150364

Remove more vector_shuffle patterns for unpack. These should be target specific nodes when they get to isel.

Update CanXFormVExtractWithShuffleIntoLoad to ensure bitcasts of loads only have one use. Matches DAGCombiner and prevents vector_shuffles from reaching isel.
