[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

[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.

[codeview] Extend the heuristic for detecting classes imported from DLLs

may not be constructed in this DLL, and therefore the vtable will live
in a different PDB.

5 years agoAMDGPU] Assembler: better support for immediate literals in assembler.
Sam Kolton [Fri, 9 Sep 2016 14:44:04 +0000 (14:44 +0000)]
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.

[mips] Fix c.<cc>.<fmt> instruction definition.

As part of this effort, remove MipsFCmp nodes and use tablegen
patterns rather than custom lowering through C++.

Unexpectedly, this improves codesize for microMIPS as previous floating
point setcc expansions would materialize 0 and 1 into GPRs before using
the relevant mov[tf].[sd] instruction. Now $zero is used directly.

Rationalise the attribute getter/setter methods on Function and CallSite.

Summary:
While woring on mapping attributes in the C API, it clearly appeared that the recent changes in the API on the C++ side left Function and Call/Invoke with an attribute API that grew in an ad hoc manner. This makes it difficult to work with it, because one doesn't know which overloads exists and which do not.

Make sure that getter/setter function exists for both enum and string version. Remove inconsistent getter/setter, unless they have many callsites.

This should make it easier to work with attributes in the future.

This doesn't change how attribute works.

[X86] Tighten up a comment which confused x64 ABI terminology.

The x64 ABI has two major function types:
 - frame functions
 - leaf functions

A frame function is one which requires a stack frame.  A leaf function
is one which does not.  A frame function may or may not have a frame
pointer.

A leaf function does not require a stack frame and may never modify SP
except via a return (RET, tail call via JMP).

A frame function which has a frame pointer is permitted to use the LEA
instruction in the epilogue, a frame function without which doesn't
establish a frame pointer must use ADD to adjust the stack pointer epilogue.

Fun fact: Leaf functions don't require a function table entry
(associated PDATA/XDATA).
