* 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

Change-Id: I35c82ec27bded3d1b62373fa6daec3ffd91105a3
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
This CL adds some extra new lines and context comments into the
spirv-dis output format. This CL adds:
- Blank line and '; Annotations' before decorations
- Blank line and '; Debug Information' before debug instructions
- Blank line and '; Types, variables and constants' before type section
- Blank line and '; Function <name>' before each function.
Issue #788
* Clone opencl.debuginfo.100 grammar from debuginfo grammar
Update version number to 200 revision 2
* Apply content from OpenCL.DebugInfo.100 extension text
* Rename grammar file
* Support OpenCL.DebugInfo.100 extended instructions
Add support for prefixing operand type names, to disambiguate
them between different instruction sets.
* Add tests for OpenCL.DebugInfo.100
* Support lookup of OpenCL.DebugInfo.100 extinst
* Add tests for enum values
* Recognize 2017-2019 as copyright date range
* Android.mk: support OpenCL.DebugInfo.100 extended instruction set
Also, stop generating core instruction tables for non-unified1 versions
of the grammar.
* Imported entity operand type is concrete
* Bazel: Suppoort OpenCL.DebugInfo.100
* BUILD.gn: Support OpenCL.DebugInfo.100
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
* Added for Instruction, BasicBlock, Function and Module
* Uses new disassembly functionality that can disassemble individual
instructions
* For debug use only (no caching is done)
* Each output converts module to binary, parses and outputs an
individual instruction
* Added a test for whole module output
* Disabling Microsoft checked iterator warnings
* Updated check_copyright.py to accept 2018
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.
Previously we required _PRINT to enable _COLOR, which forbids
outputting colored disassembly into a string in library.
This commit will allow library users to request enabling
ANSI color escape sequences.
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.
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.
This adds half-precision constants to spirv-tools.
16-bit floats are always disassembled into hex-float format,
but can be assembled from floating point or hex-float inputs.
If we later add a source/ as an -I include directory,
then avoid confusing other headers that want to include the
standard "endian.h" from /usr/include.
Also rename source/endian.cpp to source/spirv_endian.cpp
Add unit tests for all diagnostics issued by spvBinaryParse.
Handle image format operands in the binary parser and the
disassembler.
Document that the callback function pointers can be null,
in which case they are ignored.
Detect exhaustion of input when parsing an operand,
to avoid buffer overruns on some invalid input cases.
Fix the description strings for some operand types.
Make the diagnostic messages for those operand types
consistent between the assembler and binary parser.
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/29
Add members:
- words: a pointer to an array of words in the instruction,
in host native endianness.
- num_words: sizes the words member
Remove member:
- offset
This simplifies clients of spvBinaryParse, because they don't
have to handle endianness translation.
Also, it makes the binary parse API more composable, allowing
for easy chaining of binary parse clients. A binary parse client
is handed the array of words directly instead of having to reference
some external array of all the words in the SPIR-V binary. It also
allows a binary parse client to mutate the instruction stream before
handing off to a downstream consumer.
TODO(dneto): Still need to write the unit tests for spvBinaryParse
Fixes: https://github.com/KhronosGroup/SPIRV-Tools/issues/1
- Removed dead configuration in CMakeLists.txt.
- Used target_compile_options() instead of CMAKE_{C|CXX}_FLAGS.
- Turned on warnings on tests.
- Fixed various warnings for comparing signed with unsigned values.
- Removed dead code exposed by compiler warnings.
Bits 24-31: 0
Bits 16-23: SPIR-V major number (1)
Bits 8-15: SPIR-V minor number (0)
Bits 0-7: SPIR-V minor number (2)
The assembler will construct the word appropriately,
and the disassemble will print it in major.minor.revision form.
The high 16-bits are a registered generator tool.
These are registered at
https://www.khronos.org/registry/spir-v/api/spir-v.xml
The low 16-bits are tool-specific. It might be a version number,
for example, but is not constrained by the spec or by the registration
process.
The disassembler prints the tool name when we know it.
If we don't, print "Unknown" and then the numeric tool number
in parentheses.
In all cases, the disassembler prints lower 16-bit number on the
same line but after the tool name.
Also add newly registered generators:
6: Khronos LLVM/SPIR-V Translator
7: Khronos SPIR-V Tools Assembler
Previously the opcode table is declared as an global array and we
have spvOpcodeTableInitialize() modifying it. That can result in
race condition. Now spvOpcodeTabelGet() copies the whole underlying
array.
Zero and normal floating point values are printed with enough
enough digits to reproduce all the bits exactly.
Other float values (subnormal, infinity, and NaN) are printed
as hex floats.
Fix a binary parse bug: Count partially filled words in a
typed literal number operand.
TODO: Assembler support for hex numbers, and therefore reading
infinities and NaNs.
- Concrete operand types are never optional.
Split them to make this so, e.g. add SPV_OPERAND_TYPE_IMAGE
since there was SPV_OPERAND_TYPE_OPTIONAL_IMAGE.
Similarly for SPV_OPERAND_TYPE_MEMORY_ACCESS.
This entails duplicating two operand table entries.
- The above, plus some rearranging of enums, allows us to define
first and last optional operand types, and first and last
variable operand types.
This lets us simplify the code for spvOperandIsOptional, and
spvOperandIsVariable.
- Replace SPV_OPERAND_TYPE_MULTIWORD_LITERAL_NUMBER with the
more accurately named SPV_OPERAND_TYPE_TYPED_LITERAL_NUMBER.
Its special characteristic is that the type of the literal
number is determined by some previous operand in the instruction.
This is used for literals in OpSwitch, OpConstant, and OpSpecConstant.
This lets us refactor operand parsing cases in the assembler.
- Remove the special required-thing-in-optional-tuple in favour of
the corresponding concrete operand type:
SPV_OPERAND_TYPE_ID_IN_OPTIONAL_TUPLE
--> SPV_OPERAND_TYPE_ID
SPV_OPERAND_TYPE_INTEGER_LITERAL_IN_OPTIONAL_TUPLE
--> SPV_OPERAND_TYPE_INTEGER_LITERAL
- Constrain spvOpeandTypeStr to only have to work for non-variable
operand types. Add a test for this.
The binary parser has a C API, described in binary.h.
Eventually we will make it public in libspirv.h.
The API is event-driven in the sense that a callback is called
when a valid header is parsed, and for each parsed instruction.
Classify some operand types as "concrete". The binary parser uses
only concrete operand types to describe parsed instructions.
The old disassembler APIs are moved into disassemble.cpp
TODO: Add unit tests for spvBinaryParse.
This begins the refactoring of the disassembler into
two parts: A binary decoder in binary.cpp, and an
event-driven converter to text in disassemble.cpp
