Convert stderr and stdout in status to strings on assignment (#3049)
This avoids Python2 vs Python3 issues related to how we decode bytes
later on in the tests.

Switching over to using unittest instead of nosetest

5a48c0da15 SPIRV-Tools support for SPIR-V 1.5 (#2865)
* Ensure same enum values have consistent extension lists

* val: fix checking of capabilities

The operand for an OpCapability should only be
checked for the extension or core version.
The InstructionPass registers a capability, and all its implied
sub-capabilities before actually checking the operand to an
OpCapability.

* Add basic support for SPIR-V 1.5

- Adds SPV_ENV_UNIVERSAL_1_5
- Command line tools default to spv1.5 environment
- SPIR-V 1.5 incorporates several extensions.  Now the disassembler
  prefers outputing the non-EXT or non-KHR names.  This requires
  updates to many tests, to make strings match again.
- Command line tests: Expect SPIR-V 1.5 by default

* Test validation of SPIR-V 1.5 incorporated extensions

Starting with 1.5, incorporated features no longer require
the associated OpExtension instruction.

Handle id overflow in the ssa rewriter. (#2845)
* Handle id overflow in the ssa rewriter.

Remove LocalSSAElim pass at the same time.  It does the same thing as the SSARewrite pass. Then even share almost all of the same code.

Replace OpKill With function call. (#2790)
We are no able to inline OpKill instructions into a continue construct.
See #2433.  However, we have to be able to inline to correctly do
legalization.  This commit creates a pass that will wrap OpKill
instructions into a function of its own.  That way we are able to inline
the rest of the code.

The follow up to this will be to not inline any function that contains
an OpKill.

Fixes #2726

Remove unneeded future imports (#2739)
Also, adds explicitly setting python executable in the NDK build script, rewrites 
some Python2-isms to 3isms, and formats some code.

Support SPIR-V 1.4 (#2550)
* SPIR-V 1.4 headers, add SPV_ENV_UNIVERSAL_1_4

* Support --target-env spv1.4 in help for command line tools

* Support asm/dis of UniformId decoration

* Validate UniformId decoration

* Fix version check on instructions and operands

Also register decorations used with OpDecorateId

* Extension lists can differ between enums that match

Example: SubgroupMaskEq vs SubgroupMaskEqKHR

* Validate scope value for Uniform decoration, for SPIR-V 1.4

* More unioning of exts

* Preserve grammar order within an enum value

* 1.4: Validate OpSelect over composites

* Tools default to 1.4

* Add asm/dis test for OpCopyLogical

* 1.4: asm/dis tests for PtrEqual, PtrNotEqual, PtrDiff

* Basic asm/Dis test for OpCopyMemory

* Test asm/dis OpCopyMemory with 2-memory access

Add asm/dis tests for OpCopyMemorySized

Requires grammar update to add second optional memory access operand
to OpCopyMemory and OpCopyMemorySized

* Validate one or two memory accesses on OpCopyMemory*

* Check av/vis on CopyMemory source and target memory access

This is a proposed rule. See
https://gitlab.khronos.org/spirv/SPIR-V/issues/413

* Validate operation for OpSpecConstantOp

* Validate NonWritable decoration

Also permit NonWritable on members of UBO and SSBO.

* SPIR-V 1.4: NonWrtiable can decorate Function and Private vars

* Update optimizer CLI tests for SPIR-V 1.4

* Testing tools: Give expected SPIR-V version in message

* SPIR-V 1.4 validation for entry point interfaces

* Allow only unique interfaces
* Allow all global variables
* Check that all statically used global variables are listed
* new tests

* Add validation fixture CompileFailure

* Add 1.4 validation for pointer comparisons

* New tests

* Validate with image operands SignExtend, ZeroExtend

Since we don't actually know the image texel format, we can't fully
validate.  We need more context.

But we can make sure we allow the new image operands in known-good
cases.

* Validate OpCopyLogical

* Recursively checks subtypes
* new tests

* Add SPIR-V 1.4 tests for NoSignedWrap, NoUnsignedWrap

* Allow scalar conditions in 1.4 with OpSelect

* Allows scalar conditions with vector operands
* new tests

* Validate uniform id scope as an execution scope

* Validate the values of memory and execution scopes are valid scope
values
* new test

* Remove SPIR-V 1.4 Vulkan 1.0 environment

* SPIR-V 1.4 requires Vulkan 1.1

* FIX: include string for spvLog

* FIX: validate nonwritable

* FIX: test case suite for member decorate string

* FIX: test case for hlsl functionality1

* Validation test fixture: ease debugging

* Use binary version for SPIR-V 1.4 specific features

* Switch checks based on the SPIR-V version from the target environment
to instead use the version from the binary
* Moved header parsing into the ValidationState_t constructor (where
version based features are set)
* Added new versions of tests that assemble a 1.3 binary and validate a
1.4 environment

* Fix test for update to SPIR-V 1.4 headers

* Fix formatting

* Ext inst lookup: Add Vulkan 1.1 env with SPIR-V 1.4

* Update spirv-val help

* Operand version checks should use module version

Use the module version instead of the target environment version.

* Fix comment about two-access form of OpCopyMemory

Add fix storage class code. (#2434)
This pass tries to fix validation error due to a mismatch of storage classes
in instructions.  There is no guarantee that all such error will be fixed,
and it is possible that in fixing these errors, it could lead to other
errors.

Fixes #2430.

Fix python scripts to work with python3 (#2426)
Updated script to work with python3 and python2.

Added required tools.

We added a section to the readme to mention the tools that are needed to
build and test spirv-tools. For the compiler, the compilers used by the
bots are mentioned.

The bots have been changed. The windows bots will not use python 3.6 for testing. The other bots will still use python 2.7. Both Python2 and Python3 will be tested.

Fixes #2407.
Fixes #1856.

Process moer options when processing options file. (#2251)
When processing options in a file, it does have access to the
ValidatorOptions and OptimizerOptions object, so options that change
those do not work.  We just need to pass it in.

Fixes #2219.

Reduce number of test targets (#2024)
This CL takes the various opt unit tests and makes a single executable
instead of one per test. This reduces the number of build targets by
~125 when building with ninja.

Check for unreachable blocks in merge-return. (#1966)
Merge return assumes that the only unreachable blocks are those needed
to keep the structured cfg valid.  Even those must be essentially empty
blocks.

If this is not the case, we get unpredictable behaviour.  This commit
add a check in merge return, and emits an error if it is not the case.

Added a pass of dead branch elimination before merge return in both the
performance and size passes.  It is a precondition of merge return.

Fixes #1962.

Allow 0 as argument to scalar replacement. (#1917)
A limit of 0 for the scalar replacement options it used to indicate that
there is no limit.  The current implementation does not allow 0.  This
should be fixed.

Add unrolling to the legalization passes (#1903)
Adds unrolling to the legalization passes.

After enabling unrolling I found a bug when there is a self-referencing
phi node.  That has been fixed.

The test that checks for that the order of optimizations is correct also
needed to be updated.

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).
