Implement to_string(uint32_t) without using the locale (#5805)
Using the locale takes a mutex deep in the C++ library.
Avoid this on hot compilation paths, e.g. in the validator.

Fixed: #5802

Skip entire test/ folder if SPIRV_SKIP_TESTS is set. (#5548)
Without this (or similar filtering), the `spirv-tools_expect_unittests` and `spirv-tools_spirv_test_framework_unittests` Python tests at `test/tools/` get defined even when `SPIRV_SKIP_TESTS` is set.

Remove references to __FILE__ (#5462)
* Remove references to __FILE__

Uses of `__FILE__` leak the directory structure of the machine used to
build because it adds a string to the string table with the full path
name. I've removed the uses that show up in the release builds.

Fixes #5416

tools: refactorize tools flags parsing. (#5111)
* tools: refactorize tools flags parsing.

Each SPIR-V tool was handing their own flag parsing. This PR
adds a new flag parsing utility that should be flexible enough
for our usage, but generic enough so it can be shared across tools while
remaining simple to use.

* cfg: replace cfg option parsing with the new one.

* change spirv-dis parsing + title + summary

* clang format

* flags: fix static init fiasco & remove help

Static initialization order is important, and was
working just by sheer luck.

Also removing the help generation tooling. It's less flexible than the
hand-written string, and making it as-good and as-flexible brings too
much complexity.

* review feedback

Introduce spirv-diff (#4611)
spirv-diff is a new tool that produces diff-style output comparing two
SPIR-V modules.  The instructions between the src and dst modules are
matched as best as the tool can, and output is produced (in src
id-space) that shows which instructions are removed in src, added in dst
or modified between them.  The order of instructions are not retained.

Matching instructions between two SPIR-V modules is not trivial, and
thus a number of heuristics are applied in this tool.  In particular,
without debug information, it's hard to match functions as they can be
reordered.  As such, this tool is primarily useful to produce the diff
of two SPIR-V modules derived from the same source.

This tool can be useful in a number of scenarios:

- Compare the SPIR-V before and after modifying a shader
- Compare the SPIR-V produced from a shader before and after compiler
  codegen changes.
- Compare the SPIR-V produced from a shader before and after some
  transformation or optimization.
- Compare the SPIR-V produced from a shader with different compilers.

CMake: Add SPIRV_TOOLS_BUILD_STATIC flag (#3910)
If enabled the following targets will be created:

* `${SPIRV_TOOLS}-static` - `STATIC` library. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.
* `${SPIRV_TOOLS}`        - will alias to one of above, based on BUILD_SHARED_LIBS.

If disabled the following targets will be created:

* `${SPIRV_TOOLS}`        - either `STATIC` or `SHARED` based on the new `SPIRV_TOOLS_LIBRARY_TYPE` flag. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.

Defaults to `ON`, matching existing build behavior.

This flag can be used by package maintainers to ensure that all libraries are built as shared objects.

CMake: Enable building with BUILD_SHARED_LIBS=1 (#3490)
Rename the `${SPIRV_TOOLS}` target to `${SPIRV_TOOLS}-static` and alias `${SPIRV_TOOLS}` to either `${SPIRV_TOOLS}-static` or `${SPIRV_TOOLS}-shared` depending on `BUILD_SHARED_LIBS`.

Re-point all internal uses of `${SPIRV_TOOLS}` to `${SPIRV_TOOLS}-static`.

`${SPIRV_TOOLS}-static` is explicitly renamed to just `${SPIRV_TOOLS}` to ensure the name does not change from current behavior.

Build the `SPIRV-Tools-*` libraries as static, as this is what they always were.

Force the external targets `gmock` and `effcee` to be built statically. These either do not support being built as shared libraries, or require special flags.

Add support for SPV_KHR_non_semantic_info (#3110)
Add support for SPV_KHR_non_semantic_info

This entails a couple of changes:

- Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.`
- Allowing OpExtInst that reference any of those sets to contain unknown
  ext inst instruction numbers, and assume the format is always a series of IDs
  as guaranteed by the extension.
- Allowing those OpExtInst to appear in the types/variables/constants section.
- Not stripping OpString in the --strip-debug pass, since it may be referenced
  by these non-semantic OpExtInsts.
- Stripping them instead in the --strip-reflect pass.

* Add adjacency validation of non-semantic OpExtInst

- We validate and test that OpExtInst cannot appear before or between
  OpPhi instructions, or before/between OpFunctionParameter
  instructions.

* Change non-semantic extinst type to single value

* Add helper function spvExtInstIsNonSemantic() which will check if the extinst
  set is non-semantic or not, either the unknown generic value or any future
  recognised non-semantic set.

* Add test of a complex non-semantic extinst

* Use DefUseManager in StripDebugInfoPass to strip some OpStrings

* Any OpString used by a non-semantic instruction cannot be stripped, all others
  can so we search for uses to see if each string can be removed.
* We only do this if the non-semantic debug info extension is enabled, otherwise
  all strings can be trivially removed.

* Silence -Winconsistent-missing-override in protobufs

03000a3a38 Add testing framework for tools.
This forks the testing harness from https://github.com/google/shaderc
to allow testing CLI tools.

New features needed for SPIRV-Tools include:

1- A new PlaceHolder subclass for spirv shaders.  This place holder
   calls spirv-as to convert assembly input into SPIRV bytecode. This is
   required for most tools in SPIRV-Tools.

2- A minimal testing file for testing basic functionality of spirv-opt.

Add tests for all flags in spirv-opt.

1. Adds tests to check that known flags match the names that each pass
   advertises.
2. Adds tests to check that -O, -Os and --legalize-hlsl schedule the
   expected passes.
3. Adds more functionality to Expect classes to support regular
   expression matching on stderr.
4. Add checks for integer arguments to optimization flags.
5. Fixes #1817 by modifying the parsing of integer arguments in
   flags that take them.
6. Fixes -Oconfig file parsing (#1778). It reads every line of the file
   into a string and then parses that string by tokenizing every group of
   characters between whitespaces (using the standard cin reading
   operator).  This mimics shell command-line parsing, but it does not
   support quoting (and I'm not planning to).

1ef6b19260 Migrate to use unified grammar tables
Previously we keep a separate static grammar table for opcodes/
operands per SPIR-V version. This commit changes that to use a
single unified static grammar table for opcodes/operands.

This essentially changes how grammar facts are queried against
a certain target environment. There are only limited filtering
according to the desired target environment; a symbol is
considered as available as long as:

1. The target environment satisfies the minimal requirement of
   the symbol; or
2. There is at least one extension enabling this symbol.

Note that the second rule assumes the extension enabling the
symbol is indeed requested in the SPIR-V code; checking that
should be the validator's work.

Also fixed a few grammar related issues:
* Rounding mode capability requirements are moved to client APIs.
* Reserved symbols not available in any extension is no longer
  recognized by assembler.

Add grammar file for DebugInfo extended instruction set
- Each new operand enum kind in extinst.debuginfo.grammar.json maps
  to a new value in spv_operand_type_t.
- Add new concrete enum operand types for DebugInfo

Generate a C header for the DebugInfo extended instruction set

Add table lookup of DebugInfo extended instrutions

Handle the debug info operand types in binary parser,
disassembler, and assembler.

Add DebugInfo round trip tests for assembler, disassembler

Android.mk: Support DebugInfo extended instruction set

The extinst.debuginfo.grammar.json file is currently part of
SPIRV-Tools source.

It contributes operand type enums, so it has to be processed
along with the core grammar files.

We also generate a C header DebugInfo.h.

Add necessary grammar file processing to Android.mk.

720beb161a Generic intrusive linked list class.
This commit is the initial implementation of the intrusive linked list
class.  It includes the implementation in the header files, and unit
test.

The iterators are circular: incrementing end() gives begin() and
decrementing begin() gives end().  Also made it valid to
decrement end().

Expliticly defines move constructor and move assignment
- Visual Studio 2013 does not implicitly generate the move constructor or
  move assignments.  So they need to be explicit, otherwise it will try to
  use the copy constructor, which we explicitly deleted.
- Can't use "= default" either.
  Seems like VS2013 does not support explicitly using the default move
  constructors and move assignments, so I wrote them out.

1773b95737 Pull out the number parsing logic
Pull out the number parsing logic from
AssemblyContext::binaryEncodeNumericLiteral() to utilities.

The new utility function: `ParseAndEncodeNumber()` now accepts:
  * number text to parse
  * number type
  * a emit function, which is a function which will be called with each
    parsed uint32 word.
  * a pointer to std::string to be overwritten with error messages.
    (pass nullptr if expect no error message)
and returns:
  * an enum result type to indicate the status

Type/Structs moved to utility:
  * template<typename T> class ClampToZeroIfUnsignedType

New type:
* enum EncodeNumberStatus: success or error code
* NumberType: hold the number type information for the number to be parsed.
 * several helper functions are also added for NumberType.

Functions moved to utility:
  * Helpers:
    * template<typename T> checkRangeAndIfHexThenSignExtend() -> CheckRangeAndIfHex....()
  * Interfaces:
    * template<typename T> parseNumber() -> ParseNumber()
    * binaryEncodeIntegerLiteral() -> ParseAndEncodeIntegerNumber()
    * binaryEncodeFloatingPointLiteral() -> ParseAndEncodeFloatingPointNumber()
    * binaryEncodeNumericLiteral() -> ParseAndEncodeNumber()

Tests added/moved to test/ParseNumber.cpp, including tests for:
* ParseNumber(): This is moved from TextToBinary.cpp to ParseNumber.cpp
* ParseAndEncodeIntegerNumber(): New added
* ParseAndEncodeFloatingPointNumber(): New added
* ParseAndEncodeNumber(): New added

Note that the error messages are kept almost the same as before, but
they may be inappropriate for an utility function. Those will be fixed
in another CL.
