Previously, the grammar allowed many execution modes for a single
OpExecutionMode instruction.
Removes the variable- and optional- execution mode operand type
enum values.
Issue found by antiagainst@
- 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.
Except for OpConstant and OpSpecConstant, all other literal number
operands are indeed unsigned integers. So,
* Rename all *LITERAL_NUMBER* operand types to *LITERAL_INTEGER*.
* Expect unsigned integers for *LITERAL_INTEGER* operands.
* Keep MULITPLE_WORD_LITERAL untouched since it is only used by
OpConstant and OpSpecConstant.
And we want to provide the capability to specify floating-point
numbers after !<integer> in the alternate parsing mode. So,
OPTIONAL_LITERAL_NUMBER is reserved for OPTIONAL_CIV.
Fixed an issue where some of the tests were testing
the wrong word with the wrong operation. (| != ||).
Coalesced the many versions of EnumCase into one.
Added a get_value() to EnumCase to convert to a uint32_t.
Replaces ASSERT_TRUE(pointer), with ASSERT_NE(nullptr, pointer),
so that we do not do implicit pointer->bool conversion.
Removed const from some test structs since gtest needs to be
able to swap them.
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
