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.
Currently it uses a union, a write to one field, and read from
another of a different type.
Moves the endianness-determining macro close to the variable
it references.
Adds a form of spvtest::MakeInstruction which takes two vectors
of operands. That leads to simpler test code.
We can clean up some other test code, in another CL.
Make it a class, since it has non-trivial behaviour for converting
the enumerated value to a uint32_t value. (Comply with style guide.)
Merge EnumCaseWithOperands into EnumCase.
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.
Add text_fixture::TextToBinaryTestBase::CompiledInstructions,
to more easily just examine the generated instructions by skipping
over the header.
Add spvtest::MakeInstruction utility function to easily generate
a vector containing an opcode and its operands.
Use double quotes ("). They can be interspersed with
other whitespace characters, just like shell quoting.
A backslash (\) always escapes the next character.
The end of the stream always terminates the word.
Add AutoText struct to unit test utilities, to easily
make spv_text_t values and reference them as spv_text values.
