Includes:
- Multi-sequence move-to-front
- Coding by id descriptor
- Statistical coding of non-id words
- Joint coding of opcode and num_operands
Removed explicit form Huffman codec constructor
- The standard use case for it is to be constructed from initializer list.
Using serialization for Huffman codecs
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.
Replace two other, imperfect mechanisms for use-def tracking.
Use ValidationState_t::entry_points to track entry points.
Concentrate undefined-ID diagnostics in a single place.
Move validate_types.h content into validate.h due to increased
inter-dependency.
Track uses of all IDs: TYPE_ID, SCOPE_ID, ...
Also update some blurbs.
Fix entry-point accumulation and move it outside ProcessIds().
Remove validate_types.h from CMakeLists.txt.
Blurb for spvIsIdType.
Remove redundant diagnostics for undefined IDs.
Join "can not" and reformat.
- 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.
Properly support a memory access mask with a combination
of bits, including the Aligned bit. When the Aligned bit is
set, the parser should expect an alignment value literal operand.
The assembler and disassembler now use a dynamically adjusted
sequence of expected operand types. (Internally, it is a deque,
for readability.) Both parsers repeatedly pull an expected operand
type from the left of this pattern list, and try to match the next
input token against it.
The expected pattern is adjusted during the parse to accommodate:
- an extended instruction's expected operands, depending on the
extended instruction's index.
- when an operand itself has operands
- to handle sequences of zero or more operands, or pairs of
operands. These are expanded lazily during the parse.
Adds spv::OperandClass from the SPIR-V specification generator.
Modifies spv_operand_desc_t:
- adds hasResult, hasType, and operandClass array to the opcode
description type.
- "wordCount" is replaced with "numTypes", which counts the number
of entries in operandTypes. And each of those describes a
*logical* operand, including the type id for the instruction,
and the result id for the instruction. A logical operand could be
variable-width, such as a literal string.
Adds opcode.inc, an automatically-generated table of operation
descriptions, with one line to describe each core instruction.
Externally, we have modified the SPIR-V spec doc generator to
emit this file.
(We have hacked this copy to use the old semantics for OpLine.)
Inside the assembler, parsing an operand may fail with new
error code SPV_FAIL_MATCH. For an optional operand, this is not
fatal, but should trigger backtracking at a higher level.
The spvTextIsStartOfNewInst checks the case of the third letter
of what might be an opcode. So now, "OpenCL" does not look like
an opcode name.
In assembly, the EntryPoint name field is mandatory, but can be
an empty string.
Adjust tests for changes to:
- OpSampedImage
- OpTypeSampler
