* Basic support for SPIR-V 1.6
* Update SPIRV-Headers deps
* Add new environment enum for SPIR-V 1.6
* Make default environment 1.6 for most tools
* Update tests
* Disallow conditional branch with duplicate labels
* Disallow Dim=Buffer with sampled images
* Do not require the non-semantic extension after SPIR-V 1.5
* Fix endianness of string literals
To get correct and consistent encoding and decoding of string literals
on big-endian platforms, use spvtools::utils::MakeString and MakeVector
(or wrapper functions) consistently for handling string literals.
- add variant of MakeVector that encodes a string literal into an
existing vector of words
- add variants of MakeString
- add a wrapper spvDecodeLiteralStringOperand in source/
- fix wrapper Operand::AsString to use MakeString (source/opt)
- remove Operand::AsCString as broken and unused
- add a variant of GetOperandAs for string literals (source/val)
... and apply those wrappers throughout the code.
Fixes #149
* Extend round trip test for StringLiterals to flip word order
In the encoding/decoding roundtrip tests for string literals, include
a case that flips byte order in words after encoding and then checks for
successful decoding. That is, on a little-endian host flip to big-endian
byte order and then decode, and vice versa.
* BinaryParseTest.InstructionWithStringOperand: also flip byte order
Test binary parsing of string operands both with the host's and with the
reversed byte order.
Includes:
- Shift to use of spirv-header extinst.nonsemantic.shader grammar.json
- Remove extinst.nonsemantic.vulkan.debuginfo.100.grammar.json
- Enable all optimizations for Shader.DebugInfo
Also fixes scalar replacement to only insert DebugValue after all
OpVariables. This is not necessary for OpenCL.DebugInfo, but it is
for Shader.DebugInfo.
Likewise, fixes Private-to-Local to insert DebugDeclare after all
OpVariables.
Also fixes inlining to handle FunctionDefinition which can show up
after first block if early return processing happens.

This pass converts an internal form of GLSLstd450 Interpolate ops
to the externally valid form. The external form takes the lvalue
of the interpolant. The internal form can do a load of the interpolant.
The pass replaces the load with its pointer. The internal form is
generated by glslang and possibly other frontends for HLSL shaders.
The new pass is called as part of HLSL legalization after all
propagation is complete.
Also adds internal interpolate form to pre-legalization validation
* Validate SPV_KHR_workgroup_memory_explicit_layout
* Check if SPIR-V is at least 1.4 to use the extension.
* Check if either only Workgroup Blocks or only Workgroup non-Blocks
are used.
* Check that if more than one Workgroup Block is used, variables are
decorated with Aliased.
* Check layout decorations for Workgroup Blocks.
* Implicitly use main capability if the ...8BitAccess or
...16BitAccess are used.
* Allow 8-bit and 16-bit types when ...8BitAccess and ...16BitAccess
are used respectively.
* Update SPIRV-Headers dependency
Bump it to include SPV_KHR_workgroup_memory_explicit_layout.
* Add option to validate Workgroup blocks with scalar layout
Validate the equivalent of scalarBlockLayout for Workgroup storage
class Block variables from SPV_KHR_workgroup_memory_explicit_layout.
Add option to the API and command line tool.
Some OpenCL.DebugInfo.100 instructions such as DebugGlobalVariable
and DebugLocalVariable have the Type operand. This commit allows them to
use DebugTypeTemplate for the Type operand.
The updated OpenCL.DebugInfo.100 spec says that we can use
variable for "Component Count" operand of DebugTypeArray i.e.,
DebugLocalVariable or DebugGlobalVariable. This commit updates spirv-val
based on the spec update.
* Generate ext inst table for reflection
* Change build to use grammar files from SPIRV-Headers instead of
SPIRV-Tools
* Add enum for clspv reflection extended instruction set
* count it as non-semantic
* validate clspv reflection extended instruction set
* Remove local extended inst sets
* update headers deps
* Update nbuilds to use grammars from SPIRV-Headers instead of
local duplicates
Add support for SPV_KHR_non_semantic_info
This entails a couple of changes:
- Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.`
- Allowing OpExtInst that reference any of those sets to contain unknown
ext inst instruction numbers, and assume the format is always a series of IDs
as guaranteed by the extension.
- Allowing those OpExtInst to appear in the types/variables/constants section.
- Not stripping OpString in the --strip-debug pass, since it may be referenced
by these non-semantic OpExtInsts.
- Stripping them instead in the --strip-reflect pass.
* Add adjacency validation of non-semantic OpExtInst
- We validate and test that OpExtInst cannot appear before or between
OpPhi instructions, or before/between OpFunctionParameter
instructions.
* Change non-semantic extinst type to single value
* Add helper function spvExtInstIsNonSemantic() which will check if the extinst
set is non-semantic or not, either the unknown generic value or any future
recognised non-semantic set.
* Add test of a complex non-semantic extinst
* Use DefUseManager in StripDebugInfoPass to strip some OpStrings
* Any OpString used by a non-semantic instruction cannot be stripped, all others
can so we search for uses to see if each string can be removed.
* We only do this if the non-semantic debug info extension is enabled, otherwise
all strings can be trivially removed.
* Silence -Winconsistent-missing-override in protobufs
