Summary:
I originally set out to move the NameMatches closer to the relevant
function and add some unit tests. However, in the process I've found a
couple of bugs in the implementation:
- the early exits where not always correct:
- (test==pattern) does not mean the match will always suceed because
of regular expressions
- pattern.empty() does not mean the match will fail because the "" is
a valid prefix of any string
So I cleaned up those and added some tests. The only tricky part here
was that regcomp() implementation on darwin did not recognise the empty
string as a regular expression and returned an REG_EMPTY error instead.
The simples fix here seemed to be to replace the empty expression with
an equivalent non-empty one.

This change moves the SymbolBodies with isLocal() == true before the global
symbols then calculating NumLocals rather than assuming all locals are
added before globals and the first NumLocals have isLocal() == true. This
permits Thunks to be moved after the pass that adds global symbols from
synthetics to the symbol table.

Use tablegen to autogenerate isBranchtarget helper functions. This is a cleanup
that removes almost identical functions that differ only in a few constants.

Add WIG value to all of AVX instructions which ignore the W-bit in their encoding, instead of giving them the default value of 0.
This patch is needed for a follow up work on EVEX2VEX pass (replacing EVEX encoded instructions with their corresponding VEX version when possible).

The current ObjectLinkingLayer (now RTDyldObjectLinkingLayer) links objects
in-process using MCJIT's RuntimeDyld class. In the near future I hope to add new
object linking layers (e.g. a remote linking layer that links objects in the JIT
target process, rather than the client), so I'm renaming this class to be more
descriptive.

Use both LLDB- and LLVM-specific tool/library directories when LLDB is
being built stand-alone. This ensures that the freshly-built tools
(and libraries) are used correctly.
Without this patch, the test suite uses LLVM_TOOLS_DIR and LLVM_LIBS_DIR
to locate lldb, and set PATH and LD_LIBRARY_PATH. When doing
a stand-alone build, these variables represent the installed LLVM.
As a result, tests either fail due to missing lldb executable
or use an earlier installed LLDB version rather than the one being
built.
To solve this, additional LLDB_TOOLS_DIR and LLDB_LIBS_DIR variables
are added and populated using LLVM_*_OUTPUT_INTDIR. Those variables
contain directories used to output built executables and libraries.
In stand-alone builds, they represent the build-tree directories
used by LLDB. In integrated builds, they have the same values as
LLVM_*_DIR and therefore using them does not harm.
The new variables are prepended to PATH and LD_LIBRARY_PATH to ensure
that freshly built binaries are preferred over potentially earlier
installed ones. Furthermore, paths used to locate various tools are
updated to match appropriate locations.

Replaces existing approach that could only search BUILD_VECTOR nodes.
Requires getTargetConstantBitsFromNode to discriminate cases with all/partial UNDEF bits in each element - this should also be useful when we get around to supporting getTargetShuffleMaskIndices with UNDEF elements.

As discussed on D27692, this permits another domain to be used to combine a shuffle at high depths.
We currently set the required depth at 4 or more combined shuffles, this is probably too high for most targets but is a good starting point and already helps avoid a number of costly variable shuffles.
llvm-svn: 295608
Add the infrastructure to flag whether float and/or int domains are permitable.
A future patch will enable domain crossing based off shuffle depth and the value types of the source vectors.

The instructions are marked commutable, but without special handling we don't get the immediate correct.
While here also remove the masked memory forms that aren't commutable.
