If the variable_pointer extension is used:
* OpLoad's pointer argument may be the result of any of the following:
* OpSelect
* OpPhi
* OpFunctionCall
* OpPtrAccessChain
* OpCopyObject
* OpLoad
* OpConstantNull
* Return value of a function may be a pointer.
* It is valid to use a pointer as the return value of a function.
* OpStore should allow a variable pointer argument.
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.
* ValidationState_t and idUsage now store the addressing model and memory model of the SPIR-V module (this is necessary for certain instructions that need different checks depending on if the logical or physical addressing model is used)
* removed SpvOpPtrAccessChain and SpvOpInBoundsPtrAccessChain from spvOpcodeIsPointer again as these are disallowed in logical addressing mode and only allowed in physical addressing mode (which doesn't use/need spvOpcodeIsPointer in the first place)
* added SpvOpImageTexelPointer and SpvOpCopyObject to spvOpcodeIsPointer
* OpLoad/OpStore now only check if the used pointer operand originated from a valid pointer producing opcode in logical addressing mode (as per 2.16.1)
* moved bitcast pointer tests to the kernel / physical addressing model part (+cleanup)
* renamed spvOpcodeIsPointer to spvOpcodeReturnsLogicalPointer to clarify this function is only meant to be used with the logical addressing model
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.
Also
- Add type_id to spv_id_info_t.
- Use spv_id_info_t::type_id instead of words[1].
Triggered some asserts on tests, where the code incorrectly assumed
words[1] had a type. Remove the asserts and handle gracefully.
- Add tests for OpStore of a label, a void, and a function.
Note that we are more strict than Google style for one aspect:
pointer/reference indicators are adjacent to their types, not
their variables.
find . -name "*.h" -exec clang-format -i {} \;
find . -name "*.cpp" -exec clang-format -i {} \;
We need to know how to generate correct SPIRV for cases like
OpConstant %int64 42 since the current parser will encode the 42 as a
32-bit value incorrectly.
This change is the first of a pair. This one tracks types, and makes
sure that OpConstant and OpSpecConstant are only ever called with
Integer or Float types, and OpSwitch is only called with integer
generating values.
Move the definition of spv_instruction_t to an internal
header file, since it now depends on C++ and is not
used by the external interface.
Use a std::vector<uint32_t> in spv_instruction_t
instead of a fixed size array.
