* properly handle the load and store cache control operand types
Without handling these operand types, disassembling a SPIR-V module that uses the cache control extension produces an invalid operand type error.
* add a round trip test for SPV_INTEL_cache_controls
This patch adds the optional FPEncoding operand that can be added to OpTypeFloat.
At the moment there is no usable operand, so support is limited to adding the entry.

* val, core: add support for OpExtInstWithForwardRefs
This commit adds validation and support for
OpExtInstWithForwardRefs. This new instruction will be used
for non-semantic debug info, when forward references are
required.
For now, this commit only fixes the code to handle this new instruction,
and adds validation rules. But it does not add the pass to generate/fix
the OpExtInst instruction when forward references are in use.
Such pass would be useful for DXC or other tools, but I wanted to land
validation rules first.
This commit also bumps SPIRV-Headers to get this new opcode.

* 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.
Fixes an issue where an arbitrary word was cast to SpvOp, leading to
undefined behaviour if the value of the word fell outside the range of
SpvOp values.
Fixes#4504.
* Initial support for SPV_KHR_integer_dot_product
- Adds new operand types for packed-vector-format
- Moves ray tracing enums to the end
- PackedVectorFormat is a new optional operand type, so it requires
special handling in grammar table generation.
- Add SPV_KHR_integer_dot_product to optimizer whitelists.
- Pass-through validation: valid cases pass validation
Validation errors are not checked.
- Update SPIRV-Headers

This patch supports new Intel extensions added via
https://github.com/KhronosGroup/SPIRV-Headers/pull/176
SPV_INTEL_fooat_controls2 requires extra support to add
two new operand types:
SPV_OPERAND_TYPE_FPDENORM_MODE
SPV_OPERAND_TYPE_FPOPERATION_MODE

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
This Cl changes the binary parser to keep track of the instruction count
being processed. The parser will then use that instruction number as the
error number, instead of the binary word.
This should make it easier to match the error up to what the
disassembler would output for the error.
Issue #2091
[val] Add extra context to error messages.
This CL extends the error messages produced by the validator to output the
disassembly of the errored line.
The validation_id messages have also been updated to print the line number of
the error instead of the word number. Note, the error number is from the start
of the SPIR-V, it does not include any headers printed in the disassembled code.
Fixes#670, #1581
Use indirection through latest_version_spirv.h
Also, when generating enum tables, use the unified1 JSON grammar since
it now has FragmentFullyCoveredEXT but the other JSON grammars don't.
They are starting to fall behind.
Add grammar file for DebugInfo extended instruction set
- Each new operand enum kind in extinst.debuginfo.grammar.json maps
to a new value in spv_operand_type_t.
- Add new concrete enum operand types for DebugInfo
Generate a C header for the DebugInfo extended instruction set
Add table lookup of DebugInfo extended instrutions
Handle the debug info operand types in binary parser,
disassembler, and assembler.
Add DebugInfo round trip tests for assembler, disassembler
Android.mk: Support DebugInfo extended instruction set
The extinst.debuginfo.grammar.json file is currently part of
SPIRV-Tools source.
It contributes operand type enums, so it has to be processed
along with the core grammar files.
We also generate a C header DebugInfo.h.
Add necessary grammar file processing to Android.mk.
NFC. This just makes sure every file is formatted following the
formatting definition in .clang-format.
Re-formatted with:
$ clang-format -i $(find source tools include -name '*.cpp')
$ clang-format -i $(find source tools include -name '*.h')
- Parse CHANGES file with Universal Python line endings in case
the source tree was checked out with Windows line endings.
- Use our own clone of strnlen_s which might not be available

Every time an event happens in the library that the user should be
aware of, the callback will be invoked.
The existing diagnostic mechanism is hijacked internally by a
callback that creates an diagnostic object each time an event
happens.
For fulfilling this purpose, the |opcode| field in the
|spv_parsed_instruction_t| struct is changed to of type uint16_t.
Also add functions to query the information of a given SPIR-V
target environment.
Previously, the grammar allowed many execution modes for a single
OpExecutionMode instruction.
Removes the variable- and optional- execution mode operand type
enum values.

Now we have public headers arranged as follows:
$SPIRV_TOOLS_ROOT/include/spirv-tools/libspirv.h
$SPIRV_TOOLS_ROOT/include/spirv/spirv.h
$SPIRV_TOOLS_ROOT/include/spirv/GLSL.std.450.h
$SPIRV_TOOLS_ROOT/include/spirv/OpenCL.std.h
A project should use -I$SPIRV_TOOLS_ROOT/include
and then #include "spirv-tools/libspirv.h"
The headers from the SPIR-V Registry can be accessed as "spirv/spirv."
for example.
The install target should also install the headers from the SPIR-V
Registry. The libspirv.h header is broken otherwise.
The SPIRV-Tools library depends on the headers from the SPIR-V Registry.
The util/bitutils.h and util/hex_float.h are pulled into the internal
source tree. Those are not part of the public API to SPIRV-Tools.
- The SPIR-V spec generator has changed how it represents optional
operands. Now it tracks a separate boolean flag indicating optionality.
However, SPIRV-Tools still wants to represent both operand class
and optionality in the same enums space (SPV_OPERAND_TYPE_*).
So there's extra work in the patch.
- In the spec generator, OperandImage is now OperandImageOperands.
This affects enum translation in opcode.cpp.
- In the spec generator, image operands are explicitly followed by
Id, and VariableIds. However, SPIRV-Tools uses the bits set
in the image operand bitmask to control the number and meaning
of the Ids that follow. So in writing the opcode.inc syntax
table, drop all operands after OperandImageOperands.
- Some enums are now more explicitly represented in the generated
opcode.inc:
- AccessQualifier (e.g. on OpTypeImage), in both required and
optional flavours.
- MemoryAccess (e.g. on loads and stores)
- Add SPV_OPERAND_TYPE_OPTIONAL_ACCESS_QUALIFIER
- Add tests for the optional AccessQualifier operand on OpTypeImage.
- Update the AccessQualifier test for OpTypeImage so it's a round
trip test through the disassembler as well.
