Add legalizer support for G_FNEARBYINT. It's the same as G_FCEIL etc.
Since the importer allows us to automatically select this after legalization,
also add tests for selection etc. Also update arm64-vfloatintrinsics.ll.
llvm-svn: 359204
Add selection support for G_INTRINSIC_ROUND, add a selection test, and add
check lines to arm64-vfloatintrinsics.ll and f16-instructions.ll.
llvm-svn: 359046
Add it to isPreISelGenericFloatingPointOpcode, and add a regbankselect test.
Update arm64-vfloatintrinsics.ll now that we can select it.
llvm-svn: 359022
Same as G_FCEIL, G_FABS, etc. Just move it into that rule.
Add a legalizer test for G_FMA, which we didn't have before and update
arm64-vfloatintrinsics.ll.
llvm-svn: 359015
Exactly the same as G_FCEIL, G_FABS, etc.
Add tests for the fp16/nofp16 behaviour, update arm64-vfloatintrinsics, etc.

This instruction is legalized in the same way as G_FSIN, G_FCOS, G_FLOG10, etc.
Update legalize-pow.mir and arm64-vfloatintrinsics.ll to reflect the change.

This teaches the legalizer about G_FFLOOR, and lets us select G_FFLOOR in
AArch64.
It updates the existing floating point tests, and adds a select-floor.mir test.

This teaches the legalizer to handle G_FEXP in AArch64. As a result, it also
allows us to select G_FEXP.
It...
- Updates the legalizer-info tests
- Adds a test for legalizing exp
- Updates the existing fp tests to show that we can now select G_FEXP

This adds instruction selection support for G_FABS in AArch64. It also updates
the existing basic FP tests, adds a selection test for G_FABS.

This teaches GlobalISel to emit a RTLib call for @llvm.log2 when it encounters
it.
It updates the existing floating point tests to show that we don't fall back on
the intrinsic, and select the correct instructions. It also adds a legalizer
test for G_FLOG2.

llvm-svn: 352673
This teaches the legalizer about G_FSQRT in AArch64. Also adds a legalizer
test for G_FSQRT, a selection test for it, and updates existing floating point
tests.

llvm-svn: 352671
This adds support for legalizing G_FLOG into a RTLib call.
It adds a legalizer test, and updates the existing floating point tests.

llvm-svn: 352429
This adds instruction selection support for @llvm.log10 in AArch64. It teaches
GISel to lower it to a library call, updates the relevant tests, and adds a
legalizer test for log10.

llvm-svn: 352418
This contains all of the legalizer changes from D57197 necessary to select
G_FCOS and G_FSIN. It also updates several existing IR tests in
test/CodeGen/AArch64 that verify that we correctly lower the G_FCOS and G_FSIN
instructions.

This patch adds support for vector @llvm.ceil intrinsics when full 16 bit
floating point support isn't available.
To do this, this patch...
- Implements basic isel for G_UNMERGE_VALUES
- Teaches the legalizer about 16 bit floats
- Teaches AArch64RegisterBankInfo to respect floating point registers on
G_BUILD_VECTOR and G_UNMERGE_VALUES
- Teaches selectCopy about 16-bit floating point vectors
It also adds
- A legalizer test for the 16-bit vector ceil which verifies that we create a
G_UNMERGE_VALUES and G_BUILD_VECTOR when full fp16 isn't supported
- An instruction selection test which makes sure we lower to G_FCEIL when
full fp16 is supported
- A test for selecting G_UNMERGE_VALUES
And also updates arm64-vfloatintrinsics.ll to show that the new ceiling types
work as expected.

Summary:
This patch changes the legalization action for some half-precision floating-
point vector intrinsics (FSIN, FLOG, etc.) from Promote to Expand. These ops
are not supported in hardware for half-precision vectors, but promotion is
not always possible (for v8f16 operands). Changing the action to Expand fixes
an assertion failure in the legalizer when the frontend produces such ops.
In addition, a quick microbenchmark shows that, in the v4f16 case,
expanding introduces fewer spills and is therefore slightly faster than
promoting.

This adds support for allowing v8f16 vector types, thus avoiding conversions
from/to single precision for these types. This is a follow up patch of
commits r311154 and r312104, which added support for scalars and v4f16
types, respectively.

As discussed on PR27654, this patch fixes the triples of a lot of aarch64 tests and enables lit tests on windows
This will hopefully help stop cases where windows developers break the aarch64 target

This commit starts with a "git mv ARM64 AArch64" and continues out
from there, renaming the C++ classes, intrinsics, and other
target-local objects for consistency.
"ARM64" test directories are also moved, and tests that began their
life in ARM64 use an arm64 triple, those from AArch64 use an aarch64
triple. Both should be equivalent though.
This finishes the AArch64 merge, and everyone should feel free to
continue committing as normal now.
