7a35473573 Made compilation with gcc and clang more strict.
Added additional compilation flags to gcc and clang builds.
Adds -Wall -Wextra -Wno-long-long -Wshadow -Wundef -Wconversion
-WNo-sign-conversion and -Wno-missing-field-initializers
where appropriate.

Does not add -Wundef to tests, because GTEST tests undefined
macros all over the place.

43401d2ed0 Support 16-bit float in assembler and disassembler
This adds half-precision constants to spirv-tools.
16-bit floats are always disassembled into hex-float format,
but can be assembled from floating point or hex-float inputs.

f76e0f5231 Basic SSA Validation
Most uses of an ID must occur after the definition
of the ID.  Forward references are allowed for
things like OpName, OpDecorate, and various cases
of control-flow instructions such as OpBranch, OpPhi,
and OpFunctionCall.

TODO: Use CFG analysis for SSA checks.  In particular,
an ID defined inside a function body is only usable inside
that function body.  Also, use dominator info to catch
some failing cases.

Also:
* Validator test cases use (standard) assignment form.
* Update style to more closely follow the Google C++ style guide
* Remove color-diagnostics flag.
  This is enabled by default on terminals with color. Prints
  hidden ASCII for terminals that can't handle color(Emacs)
* Pass functors to SSAPass to check if the
  operand can be forward referenced based on its index value
* Return SPV_ERROR_INVALID_ID for ID related errors
  spvBinaryParse returned SPV_ERROR_INVALID_BINARY for all types of
  errors. Since spvBinaryParse does some ID validation, this was
  returning inappropriate error codes for some tests.
* Common fixture for validation tests.
  It only runs certian validation passes.
* Add a SPV_VALIDATE_SSA_BIT for testing purposes
* Fixtures now return error codes
* Add OpName support in diag message and unit tests
* Binary parsing can fail with invalid ID or invalid binary error code

Tests include:
* OpDecorate
* OpName
* OpMemberName
* OpBranchConditional
* OpSelectionMerge
* OpMemberDecorate
* OpGroupDecorate
* OpDeviceEnqueue
* Enable several tests failing in ID validation.

d9ad050a95 spvBinaryParse: fix overruns, handle image format
Add unit tests for all diagnostics issued by spvBinaryParse.

Handle image format operands in the binary parser and the
disassembler.

Document that the callback function pointers can be null,
in which case they are ignored.

Detect exhaustion of input when parsing an operand,
to avoid buffer overruns on some invalid input cases.

Fix the description strings for some operand types.
Make the diagnostic messages for those operand types
consistent between the assembler and binary parser.

ee8a007810 Clarify the non-SPV_SUCCESS case parser callbacks.
When a callback returns something other than SPV_SUCCESS,
then no futher callbacks are issued (parsing terminates early),
and no additional diagnostics are emitted.

The unit tests already check this behaviour.

750f205b63 Several unit tests for spvBinaryParse
Add a non-zero spv_result_t value SPV_REQUESTED_TERMINATION
which should be used to signal an ok result, but signals
early termination for a process, such as binary parsing.

Tests include:
 - correct contents sent to header and instruction callbacks
 - non-zero status from a callback should terminate parsing,
   but the parser should not generate its own diagnostic.

TODO: Check diagnostics generated by the parser itself.

7bff3eb6f9 spv_parsed_instruction_t cleanup
Add members:
 - words: a pointer to an array of words in the instruction,
   in host native endianness.
 - num_words: sizes the words member

Remove member:
 - offset

This simplifies clients of spvBinaryParse, because they don't
have to handle endianness translation.

Also, it makes the binary parse API more composable, allowing
for easy chaining of binary parse clients.  A binary parse client
is handed the array of words directly instead of having to reference
some external array of all the words in the SPIR-V binary.  It also
allows a binary parse client to mutate the instruction stream before
handing off to a downstream consumer.

TODO(dneto): Still need to write the unit tests for spvBinaryParse

748d585a9a Object files should depend on spirv.h and friends
Don't use SYSTEM attribute on include_directories directive
for the SPIR-V standard header files.  When you do, object files
are not considered dependent on those headers.

Checked by looking at the dependency file source/disassemble.cpp.o.d,
and by trying to compile after a trivial edit to spirv.h

Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/7

Also, use "" inclusion instead of <> inclusion for standard SPIR-V
headers.

3d348a8440 The version header word has 3 byte-size components.
Bits 24-31: 0
Bits 16-23: SPIR-V major number (1)
Bits  8-15: SPIR-V minor number (0)
Bits   0-7: SPIR-V minor number (2)

The assembler will construct the word appropriately,
and the disassemble will print it in major.minor.revision form.

201caf7001 spv_operand_type_t cleanup.
- 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.

0ca6b59bfd Refactor the binary parser.
The binary parser has a C API, described in binary.h.
Eventually we will make it public in libspirv.h.
The API is event-driven in the sense that a callback is called
when a valid header is parsed, and for each parsed instruction.

Classify some operand types as "concrete".  The binary parser uses
only concrete operand types to describe parsed instructions.

The old disassembler APIs are moved into disassemble.cpp

TODO: Add unit tests for spvBinaryParse.
