FileCheck [2/12]: Stricter parsing of -D option

Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch gives earlier and better
diagnostics for the -D option.

Prior to this change, parsing of -D option was very loose: it assumed
that there is an equal sign (which to be fair is now checked by the
FileCheck executable) and that the part on the left of the equal sign
was a valid variable name. This commit adds logic to ensure that this
is the case and gives diagnostic when it is not, making it clear that
the issue came from a command-line option error. This is achieved by
sharing the variable parsing code into a new function ParseVariable.

Sam McCall [Mon, 29 Apr 2019 08:44:01 +0000 (08:44 +0000)]
[clangd] Move clangd tests to clangd directory. check-clangd is no longer part of check-clang-tools.

Summary:
Motivation:
 - this layout is a pain to work with
 - without a common root, it's painful to express things like "disable clangd" (D61122)
 - CMake/lit configs are a maintenance hazard, and the more the one-off hacks
   for various tools are entangled, the more we see apathy and non-ownership.

This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.

(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).

Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.

default option and avoids problems from x86's inaccurate estimates.

[X86] Remove (V)MOV64toSDrr/m and (V)MOVDI2SSrr/m. Use 128-bit result MOVD/MOVQ and COPY_TO_REGCLASS instead

Summary:
The register form of these instructions are CodeGenOnly instructions that cover
GR32->FR32 and GR64->FR64 bitcasts. There is a similar set of instructions for
the opposite bitcast. Due to the patterns using bitcasts these instructions get
marked as "bitcast" machine instructions as well. The peephole pass is able to
look through these as well as other copies to try to avoid register bank copies.

Because FR32/FR64/VR128 are all coalescable to each other we can end up in a
situation where a GR32->FR32->VR128->FR64->GR64 sequence can be reduced to
GR32->GR64 which the copyPhysReg code can't handle.

To prevent this, this patch removes one set of the 'bitcast' instructions. So
now we can only go GR32->VR128->FR32 or GR64->VR128->FR64. The instruction that
converts from GR32/GR64->VR128 has no special significance to the peephole pass
and won't be looked through.

I guess the other option would be to add support to copyPhysReg to just promote
the GR32->GR64 to a GR64->GR64 copy. The upper bits were basically undefined
anyway. But removing the CodeGenOnly instruction in favor of one that won't be
optimized seemed safer.

I deleted the peephole test because it couldn't be made to work with the bitcast
instructions removed.

The load version of the instructions were unnecessary as the pattern that selects
them contains a bitcasted load which should never happen.

Fixes PR41619.

[cmake] Disable a GCC optimization when building LLVM for MIPS

GCC when compiling LLVM for MIPS can introduce a jump to an uninitialized
value when shrink wrapping is enabled. As shrink wrapping is enabled in
GCC at all optimization levels, it must be disabled. This bug exists for
all versions of GCC since 4.9.2.

This partially resolves PR37701 / GCC PR target/86069.

Reinstate r359059, reverted in r359361, with a fix to properly prevent
us emitting the operand of __builtin_constant_p if it has side-effects.

Original commit message:

Fix interactions between __builtin_constant_p and constexpr to match
current trunk GCC.

GCC permits information from outside the operand of
__builtin_constant_p (but in the same constant evaluation context) to be
used within that operand; clang now does so too. A few other minor
deviations from GCC's behavior showed up in my testing and are also
fixed (matching GCC):
  * Clang now supports nullptr_t as the argument type for
    __builtin_constant_p
    * Clang now returns true from __builtin_constant_p if called with a
    null pointer
    * Clang now returns true from __builtin_constant_p if called with an
    integer cast to pointer type
