Justin Lebar b5e884976b [NVPTX] Implement llvm.fabs.f32, llvm.max.f32, etc.
Summary:
Previously these only worked via NVPTX-specific intrinsics.

This change will allow us to convert these target-specific intrinsics
into the general LLVM versions, allowing existing LLVM passes to reason
about their behavior.

It also gets us some minor codegen improvements as-is, from situations
where we canonicalize code into one of these llvm intrinsics.

Justin Lebar b9e51397bf [StreamExecutor] Make SE work with an in-tree LLVM build.
Summary:
With these changes, we can put parallel-libs within llvm/projects and
build as normal.

This is kind of the minimal change I could figure out how to make while
still making us compatible with llvm's build system.  Some things I'm
not thrilled about include:

 * The creation of a CoreTests directory (the macros really seemed to
   want this)

 * Pulling SimpleHostPlatformDevice.h into CoreTests.  It seems to me
   this should live inside unittests/include, or maybe tests/include,
   but I didn't want to make that change in this patch.

One important piece of work that remains to be done is to make

  $ ninja check-streamexecutor

run all the tests.  Right now the only way I've figured out to run the
tests is

  $ ninja projects/parallel-libs/streamexecutor/unittests/StreamExecutorUnitTests
  $ projects/parallel-libs/streamexecutor/unittests/CoreTests/CoreTests

Summary:
This fixes a bug where we were unable to compile the following CUDA
file with libstdc++ (didn't try libc++):

  #include <future>
  void foo() { std::shared_future<int> x; }

The problem is that <future> only defines std::shared_future if
__GCC_ATOMIC_INT_LOCK_FREE > 1.  When we compiled this file for device,
the macro was set to 1, and then the class didn't exist at all.

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.

Zachary Turner 36efbfa6d8 [pdb] Print out some more info when dumping a raw stream.
We have various command line options that print the type of a
stream, the size of a stream, etc but nowhere that it can all be
viewed together.

Since a previous patch introduced the ability to dump the bytes
of a stream, this seems like a good place to present a full view
of the stream's properties including its size, what kind of data
it represents, and the blocks it occupies.  So I added the
ability to print that information to the -stream-data command
line option.

also, it changes failed test outcome from "not-crash" to "crash" (as
in "bin/not --crash").

Zachary Turner 9ba31a5efe [pdb] Pass CVRecord's through the visitor as non-const references.
This simplifies a lot of code, and will actually be necessary for
an upcoming patch to serialize TPI record hash values.

The idea before was that visitors should be examining records, not
modifying them.  But this is no longer true with a visitor that
constructs a CVRecord from Yaml.  To handle this until now, we
were doing some fixups on CVRecord objects at a higher level, but
the code is really awkward, and it makes sense to just have the
visitor write the bytes into the CVRecord.  In doing so I uncovered
a few bugs related to `Data` and `RawData` and fixed those.

The logic for upgrading a class from a forward decl to a complete type
was not checking the debug info emission level before applying the

in a different PDB.

This heuristic is still incomplete, and will miss things like abstract
base classes that are only constructed on one side of the DLL interface.

problematic, and may be useful to other projects that don't use many

2) Something something bitfields, not sure exactly what the issue or fix
is, yet.  (TODO)

Summary:
Previously we were assuming that SDNodeBits covered all of SDNode's
anonymous subclass data bitfield union.  But that's not right; it might
have size 1, in which it clearly doesn't.

This patch adds a field that does cover the whole union and adds
static_asserts to ensure it stays correct.

Sam Kolton 1eeb11bfd4 AMDGPU] Assembler: better support for immediate literals in assembler.
Summary:
Prevously assembler parsed all literals as either 32-bit integers or 32-bit floating-point values. Because of this we couldn't support f64 literals.
E.g. in instruction "v_fract_f64 v[0:1], 0.5", literal 0.5 was encoded as 32-bit literal 0x3f000000, which is incorrect and will be interpreted as 3.0517578125E-5 instead of 0.5. Correct encoding is inline constant 240 (optimal) or 32-bit literal 0x3FE00000 at least.

With this change the way immediate literals are parsed is changed. All literals are always parsed as 64-bit values either integer or floating-point. Then we convert parsed literals to correct form based on information about type of operand parsed (was literal floating or binary) and type of expected instruction operands (is this f32/64 or b32/64 instruction).
Here are rules how we convert literals:
    - We parsed fp literal:
        - Instruction expects 64-bit operand:
            - If parsed literal is inlinable (e.g. v_fract_f64_e32 v[0:1], 0.5)
                - then we do nothing this literal
            - Else if literal is not-inlinable but instruction requires to inline it (e.g. this is e64 encoding, v_fract_f64_e64 v[0:1], 1.5)
                - report error
            - Else literal is not-inlinable but we can encode it as additional 32-bit literal constant
                - If instruction expect fp operand type (f64)
                    - Check if low 32 bits of literal are zeroes (e.g. v_fract_f64 v[0:1], 1.5)
                        - If so then do nothing
                    - Else (e.g. v_fract_f64 v[0:1], 3.1415)
                        - report warning that low 32 bits will be set to zeroes and precision will be lost
                        - set low 32 bits of literal to zeroes
                - Instruction expects integer operand type (e.g. s_mov_b64_e32 s[0:1], 1.5)
                    - report error as it is unclear how to encode this literal
        - Instruction expects 32-bit operand:
            - Convert parsed 64 bit fp literal to 32 bit fp. Allow lose of precision but not overflow or underflow
            - Is this literal inlinable and are we required to inline literal (e.g. v_trunc_f32_e64 v0, 0.5)
                - do nothing
                - Else report error
            - Do nothing. We can encode any other 32-bit fp literal (e.g. v_trunc_f32 v0, 10000000.0)
    - Parsed binary literal:
        - Is this literal inlinable (e.g. v_trunc_f32_e32 v0, 35)
            - do nothing
        - Else, are we required to inline this literal (e.g. v_trunc_f32_e64 v0, 35)
            - report error
        - Else, literal is not-inlinable and we are not required to inline it
            - Are high 32 bit of literal zeroes or same as sign bit (32 bit)
                - do nothing (e.g. v_trunc_f32 v0, 0xdeadbeef)
            - Else
                - report error (e.g. v_trunc_f32 v0, 0x123456789abcdef0)

For this change it is required that we know operand types of instruction (are they f32/64 or b32/64). I added several new register operands (they extend previous register operands) and set operand types to corresponding types:
'''
enum OperandType {
    OPERAND_REG_IMM32_INT,
    OPERAND_REG_IMM32_FP,
    OPERAND_REG_INLINE_C_INT,
    OPERAND_REG_INLINE_C_FP,
}
'''

This is not working yet:
    - Several tests are failing
    - Problems with predicate methods for inline immediates
    - LLVM generated assembler parts try to select e64 encoding before e32.
More changes are required for several AsmOperands.
