Matt Arsenault eac8acfa94 AMDGPU: Don't use struct type for argument layout
This was introducing unnecessary padding after the explicit
arguments, depending on the alignment of the total struct type.
Also has the side effect of avoiding creating an extra GEP for
the offset from the base kernel argument to the explicit kernel
argument offset.

Tom Stellard cba2181e77 AMDGPU: Separate R600 and GCN TableGen files
Summary:
We now have two sets of generated TableGen files, one for R600 and one
for GCN, so each sub-target now has its own tables of instructions,
registers, ISel patterns, etc.  This should help reduce compile time
since each sub-target now only has to consider information that
is specific to itself.  This will also help prevent the R600
sub-target from slowing down new features for GCN, like disassembler
support, GlobalISel, etc.

Matt Arsenault 1fa5b55214 AMDGPU: Round up kernel argument allocation size
AFAIK the driver's allocation will actually have to round this
up anyway. It is useful to track the rounded up size, so that
the end of the kernel segment is known to be dereferencable so
a wider s_load_dword can be used for a short argument at the end
of the segment.

Tom Stellard f02d6fd47c AMDGPU: Remove #include "MCTargetDesc/AMDGPUMCTargetDesc.h" from common headers
Summary:
MCTargetDesc/AMDGPUMCTargetDesc.h contains enums for all the instuction
and register defintions, which are huge so we only want to include
them where needed.

This will also make it easier if we want to split the R600 and GCN
definitions into separate tablegenerated files.

I was unable to remove AMDGPUMCTargetDesc.h from SIMachineFunctionInfo.h
because it uses some enums from the header to initialize default values
for the SIMachineFunction class, so I ended up having to remove includes of
SIMachineFunctionInfo.h from headers too.

We've been running doxygen with the autobrief option for a couple of

them all.

Marek Olsak 0a5f9fa9c2 AMDGPU: enable 128-bit for local addr space under an option
Author: Samuel Pitoiset

ds_read_b128 and ds_write_b128 have been recently enabled
under the amdgpu-ds128 option because the performance benefit
is unclear.

Though, using 128-bit loads/stores for the local address space
appears to introduce regressions in tessellation shaders. Not
sure what is broken, but as ds_read_b128/ds_write_b128 are not
enabled by default, just introduce a global option and enable
128-bit only if requested (until it's fixed/used correctly).

v2: - fix regressions in merge-stores.ll and multiple_tails.ll

Quentin Colombet 8e98e02784 Reapply "[GlobalISel] Remove the GISelAccessor API."
This reverts commit r310425, thus reapplying r310335 with a fix for link
issue of the AArch64 unittests on Linux bots when BUILD_SHARED_LIBS is ON.

Original commit message:
[GlobalISel] Remove the GISelAccessor API.

Its sole purpose was to avoid spreading around ifdefs related to
building global-isel. Since r309990, GlobalISel is not optional anymore,
thus, we can get rid of this mechanism all together.

NFC.

----
The fix for the link issue consists in adding the GlobalISel library in
the list of dependencies for the AArch64 unittests. This dependency
comes from the use of AArch64Subtarget that needs to know how
to destruct the GISel related APIs when being detroyed.

Thanks to Bill Seurer and Ahmed Bougacha for helping me reproducing and
understand the problem.

Sam Kolton 06ed4a14fd [AMDGPU] SDWA: several fixes for V_CVT and VOPC instructions
Summary:
1. Instruction V_CVT_U32_F32 allow omod operand (see SIInstrInfo.td:1435). In fact this operand shouldn't be allowed here. This fix checks if SDWA pseudo instruction has OMod operand and then copy it.
2. There were several problems with support of VOPC instructions in SDWA peephole pass.

Sam Kolton e88fc4046f [AMDGPU] SDWA: add support for GFX9 in peephole pass
Summary:
Added support based on merged SDWA pseudo instructions. Now peephole allow one scalar operand, omod and clamp modifiers.
Added several subtarget features for GFX9 SDWA.
This diff also contains changes from D34026.
Depends D34026

Matt Arsenault 40cf5b3d29 AMDGPU: Fix crash when disassembling VOP3 mac
The unused dummy src2_modifiers is missing, so it crashes
when trying to print it.

I tried to fully remove src2_modifiers, but there are some
irritations in the places where it is converted to mad since
it starts to require modifying use lists while iterating over
them.

Yaxun Liu ab3be33d40 [AMDGPU] Get address space mapping by target triple environment
As we introduced target triple environment amdgiz and amdgizcl, the address
space values are no longer enums. We have to decide the value by target triple.

The basic idea is to use struct AMDGPUAS to represent address space values.
For address space values which are not depend on target triple, use static
const members, so that they don't occupy extra memory space and is equivalent
to a compile time constant.

Since the struct is lightweight and cheap, it can be created on the fly at
the point of usage. Or it can be added as member to a pass and created at
the beginning of the run* function.

Matt Arsenault aac82e218f AMDGPU: Redefine clamp node as clamp 0.0-1.0
Change implementation to use max instead of add.
min/max/med3 do not flush denormals regardless of the mode,
so it is OK to use it whether or not they are enabled.

Also allow using clamp with f16, and use knowledge
of dx10_clamp.
