Default-constructed Pass/PassManager will have a MessageConsumer
which ignores all messages. SetMessageConsumer() should be called
to supply a meaningful MessageConsumer.
Requires use of SPIRV-Headers that has support
for SPV_KHR_shader_ballot.
Adds assembler, disassembler, binary parser support.
Adds general support for allowing an operand to be
only enabled by a set of extensions.
TODO: Validator support for extension checking.
* Use PIMPL idiom in the C++ interface.
* Clean up interface for assembling and disassembling.
* Add validation into C++ interface.
* Add more tests for the C++ interface.
Add the following macros for logging purpose:
* SPIRV_ASSERT
* SPIRV_DEBUG
* SPIRV_UNIMPLEMENTED
* SPIRV_UNREACHABLE
The last two is always turned on, while the first two can only
be turned on in debug build.
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.
Defer removal of a Phi's result id from the undefined-forward-reference
set until after you've scanned the arguments. The reordering is only
significant for Phi.

ParseNumber(): Returns false if the given string is a nullptr.
ParseAndEncodeXXXX(): Returns kInvalidText and populate error message:
"The given text is a nullptr", if the givne string is a nullptr.
The pass instance is constructed with a map from spec id (uint32_t) to
default values in string format. The default value strings will be
parsed to numbers according to the target spec constant type.
If the Spec Id decoration is found to be applied on multiple different
target ids, that decoration instruction (OpDecorate or OpGroupDecorate)
will be skipped. But other decoration instrucitons may still be
processed.
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.
De-duplicate constants and unifies the uses of constants for a SPIR-V
module. If two constants are defined exactly the same, only one of them
will be kept and all the uses of the removed constant will be redirected
to the kept one.
This pass handles normal constants (defined with
OpConstant{|True|False|Composite}), some spec constants (those defined
with OpSpecConstant{Op|Composite}) and null constants (defined with
OpConstantNull).
There are several cases not handled by this pass:
1) If there are decorations for the result id of a constant defining
instruction, that instruction will not be processed. This means the
instruction won't be used to replace other instructions and other
instructions won't be used to replace it either.
2) This pass does not unify null constants (defined with
OpConstantNull instruction) with their equivalent zero-valued normal
constants (defined with OpConstant{|False|Composite} with zero as the
operand values or component values).
Also removed the default argument value of `skip_nop` for function
`SinglePassRunAndCheck()` and `SinglePassRunAndDisassemble()`. This is
required to support variadic arguments.
Use libspirv::CapabilitySet instead of a 64-bit mask.
Remove dead function spvOpcodeRequiresCapability and its tests.
The JSON grammar parser is simplified since it just writes the
list of capabilities as a braced list, and takes advantage of
the CapabilitySet intializer-list constructor.
