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
The code in source/message was only used in a single set of tests to
format the output results. This CL changes the test to verify the
message instead of all the error values and removes the source/message
code.
Currently the utils/ folder uses both spvutils:: and spvtools::utils.
This CL changes the namespace to consistenly be spvtools::utils to match
the rest of the codebase.
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')
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.
Pull out the number parsing logic from
AssemblyContext::binaryEncodeNumericLiteral() to utilities.
The new utility function: `ParseAndEncodeNumber()` now accepts:
* number text to parse
* number type
* a emit function, which is a function which will be called with each
parsed uint32 word.
* a pointer to std::string to be overwritten with error messages.
(pass nullptr if expect no error message)
and returns:
* an enum result type to indicate the status
Type/Structs moved to utility:
* template<typename T> class ClampToZeroIfUnsignedType
New type:
* enum EncodeNumberStatus: success or error code
* NumberType: hold the number type information for the number to be parsed.
* several helper functions are also added for NumberType.
Functions moved to utility:
* Helpers:
* template<typename T> checkRangeAndIfHexThenSignExtend() -> CheckRangeAndIfHex....()
* Interfaces:
* template<typename T> parseNumber() -> ParseNumber()
* binaryEncodeIntegerLiteral() -> ParseAndEncodeIntegerNumber()
* binaryEncodeFloatingPointLiteral() -> ParseAndEncodeFloatingPointNumber()
* binaryEncodeNumericLiteral() -> ParseAndEncodeNumber()
Tests added/moved to test/ParseNumber.cpp, including tests for:
* ParseNumber(): This is moved from TextToBinary.cpp to ParseNumber.cpp
* ParseAndEncodeIntegerNumber(): New added
* ParseAndEncodeFloatingPointNumber(): New added
* ParseAndEncodeNumber(): New added
Note that the error messages are kept almost the same as before, but
they may be inappropriate for an utility function. Those will be fixed
in another CL.
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.
- 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.
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
Fixing some C++ conversion errors.
* Implicit conversion from int to bool.
* Implicit conversion from size_t to uint32_t.
* Implicit conversion from char* to uint8_t.
Adding no-op color operators so unhandled platforms can still link.
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.
Replaced uint64_t with size_t in the places that make sense and
added spv_const_binary{,_t} to allow the interface to accept non
modifiable spirv where appropriate.
- 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.
