This was hardcoding some make rules instead of relying on
Makefile.rules, which was causing some of the logic to be
incorrect for Windows.

[sanitizer] Fix file access modes in SanitizerCommon.InternalMmapWithOffset and SanitizerCommon.FileOps

llvm-svn: 232972

On AArch64, the -fallow-half-args-and-returns option is the default.
With it, the half type is considered legal (rather than the i16 used
normally for __fp16), but no operation is, except conversions and
load/stores and such.

The previous behavior was tantamount to saying LangOpts.NativeHalfType
was implied by LangOpts.HalfArgsAndReturns, which isn't true.
Instead, teach the various parts of CodeGen that already know about
half (using the intrinsics or not) about this weird in-between case,
where the "half" type is legal, but operations on it aren't.

This is a smaller intermediate step to the end-goal of removing the
intrinsic, always using "half", and letting the backend legalize.

Builds on r232968.

- replace hard tabs with 4-space indents
- delete EOL whitespace

llvm-svn: 232969

Fix the CodeGen so that for types bigger than float, instead of
converting to fp16 via the sequence "InTy -> float -> fp16", we
perform conversions in just one step.  This avoids the double
rounding which potentially changes results from a natural
IEEE-754 operation.

Summary:
This has been discovered while experimenting with the gecko linker on android.
In general, assert()'ing on "user input" is a bad idea.

Test Plan: Run unit tests.

This is a generic implementation which just calls sqrt.  Targets should
override this if they want a faster implementation.

v2:
  - Alphabetize SOURCES

llvm-svn: 232965

This implementation was ported from the AMD builtin library
and has been tested with piglit, OpenCV, and the ocl conformance tests.

v2:
  - Remove unnecessary copyright.

llvm-svn: 232964

v2:
  - Move common code into a macro
  - Use the same constant for all vector types.

llvm-svn: 232963

This change is incorrect since it converts double rounding into single rounding,
which can produce different results. Instead this optimization will be done by
modifying Clang's codegen to not produce double rounding in the first place.

This reverts commit r232954.

This will help avoid naming conflicts with functions defined in
kernels linking with libclc.

It is required because the name of the executable exceeded the maximum
allowed file name on android.

Anton tried this 5 years ago but it was reverted due to extra VMOVs
being emitted. This can be easily fixed with a liberal application
of patterns - matching loads/stores and extractelts.

This function assumed that SMRD instructions always have immediate

Specifically when the conversion is done in two steps, f16 -> f32 -> f64.

For example:

%1 = tail call float @llvm.convert.from.fp16.f32(i16 %0)
%conv = fpext float %1 to double

vcvtb.f64.f16

Summary:
But still handle them the same way since I don't know how they differ on
this target.

Clang also has code for 'Ump', 'Utf', 'Usa', and 'Ush' but calls
llvm_unreachable() on this code path so they are not converted to a
constraint id at the moment.

No functional change intended.
