RegAllocGreedy has been the default for six months now.

Deleting RegAllocLinearScan makes it possible to also delete
VirtRegRewriter and clean up the spiller code.

Counting the number of occurences of each opcode is not a useful test.

Or maybe we are just getting lucky.

Filed PR11364 to track the problem.  Should the register allocator
eliminate dead code?

This test was committed with a bugfix to RemoveCopyByCommutingDef, but
that optimization is no longer triggered by this test.

This test is for a very specific LocalRewriter bug.  LocalRewriter is
going away.

llvm-svn: 144469

I don't think this test does what is was supposed to do, and
LocalRewriter is going away anyway.

This test doesn't expose the issue with RAGreedy.

I filed PR11363 to track the missing InlineSpiller feature.

The test is checking that the output doesn't contains any 'mov '
strings. It does contain movl, though.

Add more AVX2 shift lowering support. Move AVX2 variable shift to use patterns instead of custom lowering code.

methods but also class methods for Objective-C.

Clang emits Objective-C method names with '\1' at the
beginning, and the JIT has pre-existing logic to try
prepending a '\1' when searching a module for an
instance method (that is, a method whose name begins
with '-').  I simply extended it to do the same thing
when it encountered a class method (a method whose
name begins with '+').

build: Attempt to rectify inconsistencies between CMake and LLVMBuild versions of explicit dependencies.
 - The hope is that we have a tool/test to verify these are accurate (and tight) soon.

instance and a concrete inlined instance are the use of DW_TAG_subprogram
instead of DW_TAG_inlined_subroutine and the who owns the tree.

We were also omitting DW_AT_inline from the abstract roots. To fix this,
make sure we mark abstract instance roots with DW_AT_inline even when
we have only out-of-line instances referring to them with DW_AT_abstract_origin.

FileCheck is not a very good tool for tests like this, maybe we should add
a -verify mode to llvm-dwarfdump.

These immediate operands all use the same simple logic for rendering to
MCInst, so have them share the method for doing so.

Some cleanup and bulletproofing for node replacement in LegalizeDAG.  To maintain LegalizeDAG invariants, whenever we a node is replaced, we must attempt to delete it, and if it still
has uses after it is replaced (which can happen in rare cases due to CSE), we must revisit it.

It's ignored by the assembler when present, but is legal syntax. Other
instructions have something similar, but for some mnemonics it's
only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.
