Other environments do not.
Add tests for OpenGL 4.5 and SPIR-V universal 1.0 to ensure
they still check monotonic layout.
For universal 1.0, we're assuming it otherwise follows Vulkan
rules for block layout.

Due to a compiler issue on the Kokoro Windows VM, we currently do not
run the Debug build on Kokoro.
Therefore, I am disabling all Travis jobs and the appveyor Release jobs.
For the instructions which execute after the IdPass check we can provide
the Instruction instead of the spv_parsed_instruction_t. This
Instruction class provides a bit more context (like the source line)
that is not available from spv_parsed_instruction_t.
This CL moves the validation code to the val:: namespace. This makes it
clearer which instance of the Instruction and other classes are being
referred too.
Most of the link code is marked as static. This CL introduces an anonymous namespace
and removes the static methods. The last two methods are exposed in the public API and
have been left in the spvtools namespace.
This CL moves the files in opt/ to consistenly be under the opt::
namespace. This frees up the ir:: namespace so it can be used to make a
shared ir represenation.
Currently the utils/ folder uses both spvutils:: and spvtools::utils.
This CL changes the namespace to consistenly be spvtools::utils to match
the rest of the codebase.
Implement rules for row-major matrices
Use ArrayStride and MatrixStride to compute sizes
Propagate matrix stride and RowMajor/ColumnMajor through array members of structs.

Fixes#1618.
Adds a check that validates acceptable exits from case constructs. Case
constructs may only exit to another case construct, the corresponding
merge, an outer loop continue or outer loop merge.
Fixes#1664 : PushConstant with Block follows storage buffer rules
PushConstant variables were being checked with block rules, which are
too strict.
Fixes#1606 : StorageBuffer with Block layout follows buffer rules
StorageBuffer variables were not being checked before.
Fix layout messages: say storage class and decoration
We need to provide more information about storage class and decoration.
The folding routines are currently global functions. They also rely on
data in an std::map that holds the folding rules for each opcode. This
causes that map to not have a clear owner, and therefore never gets
deleted.
There has been a request to delete this map. To implement this, we will
create a InstructionFolder class that owns the maps. The IRContext will
own the InstructionFolder instance. Then the global functions will
become public memeber functions of the InstructionFolder.
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/1659.
There are a few locations where we need to handle duplicate types. We
cannot merge them because they may be needed for reflection. When this
happens we need do some extra lookups in the type manager.
The specific fixes are:
1) When generating a constant through `GetDefiningInstruction` accept
and use an id for the desired type of the constant. This will make sure
you get the type that is needed.
2) In Private-to-local, make sure we to update the def-use chains when a
new pointer type is created.
3) In the type manager, make sure that `FindPointerToType` returns a
pointer that points to the given type and not a duplicate type.
4) In scalar replacment, make sure the null constants that are created
are the correct type.
Many optimization will run on function scope symbols only. When symbols
are moved from private scope to function scople, then these optimizations
can do more.
I believe it is a good idea to run this pass with both -O and -Os. To
get the most out of it it should be run ASAP after inlining and something
that remove all of the dead functions.

Produce better error diagnostics in the CFG validation.
This CL fixes up several issues with the diagnostic error line output
in the CFG validation code. For the cases where we can determine a
better line it has been output. For other cases, we removed the
diagnostic line and the error line number from the results.
Fixes#1657
Revert "Don't merge types of resources"
This reverts commit f393b0e480, but leaves
the tests that were added. Added new test. These test are the so that,
if someone tries the same change I made, they will see the test that
they need to handle.
Don't run remove duplicates in -O and -Os
Romve duplicates was run to help reduce compile time when looking for
types in the type manager. I've run compile time test on three sets
of shaders, and the compile time does not seem to change.
It should be safe to remove it.
The Compact IDs pass can corrupt the CFG, but first the CFG has to
be setup. To do this, a test that builds the CFG, then performs the
compact IDs pass, then checks context consistency.
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/1648
During the compact IDs optimization pass, the result IDs of some
basic blocks can change. In spite of this, GetPreservedAnalyses
indicated that the CFG was preserved. But the CFG relies on
the basic blocks having the same IDs. Simply removing this flag
resolves the issue by preventing the CFG check.
Also Removes combinators and namemap preserved analyses from
compact IDs pass.
subprocess.Popen returns byte data by default. Python2 was happy
to try to execute string operations on such data and hope for the
best, but python3 is more persnickety. Luckily, there's a simple
way to indicate to the Popen class that text data is wanted that
benefits the script. Just specifying universal_newlines will cause
the returned data to be text and also convert any system-specific
newlines to '\n' which the script relies on anyway.
Enabled on Mac as an incidental change after confirming that the
script works there just as well as it does on Linux.
It probably works on FreeBSD too, but I retired my BSD system years
ago. So I have no way to check.
Don't run it on Windows.
- It didn't work after all. It was just detecting non-posix and
returning success.
When doing reflection users care about the names of the variable, the
name of the type, and the name of the members. Remove duplicates breaks
this because it removes the names one of the types when merging.
To fix this we have to keep the different types around for each
resource. This commit adds code to remove duplicates to look for the
types uses to describe resources, and make sure they do not get merged.
However, allow merging of a type used in a resource with something not
used in a resource. Was done when the non resource type came second.
This could have a negative effect on compile time, but it was not
expected to be much.

Fixes#937
Stop std140/430 validation when runtime array is encountered.
Check for standard uniform/storage buffer layout instead of std140/430.
Added validator command line switch to skip block layout checking.
Validate structs decorated as Block/BufferBlock only when they
are used as variable with storage class of uniform or push
constant.
Expose --relax-block-layout to command line.
dneto0 modification:
- Use integer arithmetic instead of floor.
We need this to reduce the test time on Visual Studio debug builds.
AppVeyor times out at 300s for a process.
Artificially lower the local variable limit check for testing purposes.
We don't get much value from using the full 500K+ variables.
Use a limit of 5000 instead.

This CL adds the necessary files to use gclient and the depot_tools with
the SPIRV-Tools directory. This allows doing things like `git cl format`
to format code pre-upload and `git cl presubmit -uf` to run presubmit
checks over the code.
The dependencies are all added to the DEPS file and will be
auto-downloaded. They are all pin'd to specific revisions so everyone
has the same checkout. Clang is included in the checkout so it will be
consistent over usages.

Add SPV_ENV_WEBGPU_0 for work-in-progress WebGPU.

Silence unused variable warnings when !defined(SPIRV_EFFCE)
Limit visibility of validate_instruction.cpp's symbols
Only InstructionPass needs to be visible so all other functions are put
in an anonymous namespace inside the libspirv namespace.
Also add a corresponding check for capabilities in the validator.
Update previously existing test cases where an instruction used to fail
assembling because of a version check, but now they succeed because the
instruction is also guarded by a capability. Now it should assemble.
Add tests to ensure that capabilities are checked appropriately.
The explicitly reserved instructions OpImageSparseSampleProj*
now assemble, but they fail validation.
Fixes#1624
[val] Add extra context to error messages.
This CL extends the error messages produced by the validator to output the
disassembly of the errored line.
The validation_id messages have also been updated to print the line number of
the error instead of the word number. Note, the error number is from the start
of the SPIR-V, it does not include any headers printed in the disassembled code.

definitions being looked at can be found. This may not be true if we
