Craig Topper 3dc066754c [TableGen][ISel] When factoring ScopeMatcher, if the child of the ScopeMatcher we're working on is also a ScopeMatcher, merge all its children into the one we're working on.
There were several cases in X86 where we were unable to fully factor a ScopeMatcher but created nested ScopeMatchers for some portions of it. Then we created a SwitchType that split it up and further factored it so that we ended up with something like this:

SwitchType
  Scope
    Scope
      Sequence of matchers
      Some other sequence of matchers
    EndScope
    Another sequence of matchers
  EndScope
...Next type

This change turns it into this:

SwitchType
  Scope
    Sequence of matchers
    Some other sequence of matchers
    Another sequence of matchers
  EndScope
...Next type

Several other in-tree targets had similar nested scopes like this. Overall this doesn't save many bytes, but makes the isel output a little more regular.

Jacob Baungard Hansen 3bc6fe78f6 [Sparc] Use target name instead of namespace as prefix for MCRegisterClasses array
Summary:
For Sparc the namespace (SP) is different from the target name (Sparc),
which causes the name of the array in this declaration to differ from

Craig Topper 5e87d5264f [TableGen][ISel] Do a better job of factoring ScopeMatchers created during creation of SwitchTypeMatcher.
Previously we were factoring when the ScopeMatcher was initially created, but it might get more Matchers added to it later. Delay factoring until we have fully created/populated the ScopeMatchers.

This reduces X86 isel tables by 154 bytes.

Daniel Sanders 72db2a390a Check that emitted instructions meet their predicates on all targets except ARM, Mips, and X86.
Summary:
* ARM is omitted from this patch because this check appears to expose bugs in this target.
* Mips is omitted from this patch because this check either detects bugs or deliberate
  emission of instructions that don't satisfy their predicates. One deliberate
  use is the SYNC instruction where the version with an operand is correctly
  defined as requiring MIPS32 while the version without an operand is defined
  as an alias of 'SYNC 0' and requires MIPS2.
* X86 is omitted from this patch because it doesn't use the tablegen-erated
  MCCodeEmitter infrastructure.

Patches for ARM and Mips will follow.

Summary:
This change is preparation for a change that will allow targets to verify that the instructions

legalization/lowering/instruction-selection doesn't incorrectly select code for a different
subtarget than intended. Such cases are not caught by the integrated assembler when emitting
instructions directly to an object file.

A relocatable immediate is either an immediate operand or an operand that

in non-PIC code.

Start using relocImm for 32-bit and 64-bit MOV instructions, and for operands
of type "imm32_su". Remove a number of now-redundant patterns.

Brian Gesiak 8d89c3c6f7 [lit] Run unit tests as part of lit test suite
Summary:
The Python file `utils/lit/lit/ShUtil.py` contains:

1. Logic used by lit itself
2. A set of unit tests for that logic, which can be run by invoking
  `python utils/lit/lit/ShUtil.py`

Move these unit tests to a `tests/unit` subdirectory of lit, and run
the tests as part of lit's test suite. This ensures that, should the
lit test suite be included in LLVM's own regression test suite, these
unit tests will also be run.

(Instructions on how to run lit's test suite can be found in
`utils/lit/README.txt`.)

Brian Gesiak 11c48475c4 [lit] Remove (or allow specific) unused imports
Summary:
Using Python linter flake8 on the utils/lit reveals several linter
warnings designated "F401: Unused import". Fix or silence these
warnings.

Some of these unused imports are legitimate, while some are part of lit's API.
For example, users of lit expect to be able to access `lit.formats.ShTest` in
their `lit.cfg`, despite the module hierarchy for that symbol actually being
`lit.formats.shtest.ShTest`. To silence linter errors for these lines,
include a "noqa" directive.

Adam Nemet 848556a0e2 New utility to visualize optimization records
This is a new tool built on top of the new YAML ouput generated from
optimization remarks.  It produces HTML for easy navigation and
visualization.

The tool assumes that hotness information for the remarks is available
(the YAML file was produced with PGO).  It uses hotness to list the
remarks prioritized by the hotness on the index page.  Clicking the
source location of the remark in the list takes you the source where the
remarks are rendedered inline in the source.

For now, the tool is meant as prototype.

It's written in Python.  It uses PyYAML to parse the input.

Chris Bieneman 1f49329e81 [lit] Use argparse instead of optparse
Summary:
optparse is deprecated in Python 2.7, which is the minimum version of
Python required to run the LLVM test suite. Replace its usage in lit
with argparse, optparse's 2.7 replacement module.

argparse has several benefits over optparse, but this commit does not
make use of those benefits yet. Instead, it simply uses the new API,
and attempts to keep the number of changes to a minimum.

Confirmed that lit's test suite, as well as LLVM's regression test suite,
still pass with these changes.

Chris Bieneman fc6e46a314 [lit] Compare to None using identity, not equality
Summary:
In Python, `None` is a singleton, so checking whether a variable is
`None` may be done with `is` or `is not`. This has a slight advantage
over equiality comparisons `== None` and `!= None`, since `__eq__` may
be overridden in Python to produce sometimes unexpected results.

Using `is None` and `is not None` is also recommended practice in
https://www.python.org/dev/peps/pep-0008:

> Comparisons to singletons like `None` should always be done with `is` or
> `is not`, never the equality operators.

Michael Gottesman 31e9363a3e [cmake] Export gtest/gtest_main and its dependencies via a special build tree only cmake exports file.
Previously, gtest/gtest_main were not exported via cmake. The intention here was
to ensure that users whom are linking against the LLVM install tree would not
get the gtest/gtest_main targets. This prevents downstream projects that link
against the LLVM build tree (i.e. Swift) from getting this dependency
information in their cmake builds. Without such dependency information, linker
issues can result on linux due to LLVMSupport being put before gtest on the
linker command line.

This commit preserves behavior that we want for the install tree, while adding
support for the build tree by:

1. The special casing for gtest/gtest_main in the add_llvm_library code is
removed in favor of a flag called "BUILDTREE_ONLY". If this is set, then the
library is communicating that it is only meant to be exported into the build
tree and is not meant to be installed or exported via the install tree. This
part is just a tweak to remove the special case, the underlying code is the
same.

2. The cmake code that exports cmake targets for the build tree has special code
to import an additional targets file called
LLVMBuildTreeOnlyExports.cmake. Additionally the extra targets are added to the
LLVMConfig.cmake's LLVM_EXPORTED_TARGETS variable. In contrast, the
"installation" cmake file uses the normal LLVM_EXPORTS_TARGETS as before and
does not include the extra exports file. This is implemented by
defining/undefining variables when performing a configure of the build/install
tree LLVMConfig.cmake files.
