In newer versions of protobuf the Status building code has been made
internal, so that embedders cannot build their own instances like is
being done here.
Changing this code to just use the .ok() method on the status object,
since if the status is OK or not is what is actually being tested.
This will make it easier in the future to update external/protobuf.
The copyright check has hardcoded the years that can appear in the
copyright check. This means is has to be constantly updated as new
years or range of years are needed.
We try to avoid this, at least for a while. We allow years up to 2027.
The ranges for the years allow any combination of from 2014 to 2027.
* Update test for parsing memory access masks
Needed to support SPV_INTEL_memory_access_aliasing extension
There is a negative test that checks unused mask bits.
Some of those bits are now sued by the new Intel extension.
* Update deps for new SPIRV-Headers
Previously, array sizes were presumed to be OpConstant, which is not
necessarily true. This change ensures OpSpecConstant array sizes as
matched exactly, instead of taken as OpConstant and matched by value.
* Reimplement LCS used by spirv-diff
Two improvements are made to the LCS algorithm:
- The LCS algorithm is reimplemented to use a std::stack instead of
being recursive. This prevents stack overflow in the LCSTest.Large
test.
- The LCS algorithm uses an NxM table. Previously, entries of this
table were {size_t, bool, bool}, which is now packed in 32 bits. The
first entry can assume a maximum value of min(N, M), which
realistically for SPIR-V diff will not be larger than 1 billion
instructions. This reduces memory usage of LCS by 75%.
This partially reverts 845f3efb8a and
enables LCS tests.
* Stabilize the output of spirv-diff
std::map is used instead of std::unordered_map to ensure the output of
spirv-diff is identical everywhere.
This partially reverts 845f3efb8a and
enables spirv-diff tests.
Scalar replacement generates a null when there value for a member will
not be used. The null is used to make sure things are
deterministic in case there is an error.
However, some type cannot be null, so we will change that to use undef.
To keep the code simpler we will always use the undef.
Fixes#3996
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.
The handling of the RayQueryKHR type is not complete in the type
manager. The tests were not picking this up. I've added a test to make
sure that the `GenerateAllTypes` function actually does generate all of
the types. Once it is added there other tests should pick up on the
other parts that were missing.

Two deps changes branch names, and roll_deps.sh must be updated.
We also don't want the script to fail just because one of the deps is
already up-to-date. Set `+e` before rolling the deps.
Add a pass to spread Volatile semantics to variables with SMIDNV,
WarpIDNV, SubgroupSize, SubgroupLocalInvocationId, SubgroupEqMask,
SubgroupGeMask, SubgroupGtMask, SubgroupLeMask, or SubgroupLtMask BuiltIn
decorations or OpLoad for them when the shader model is the ray
generation, closest hit, miss, intersection, or callable shaders. This
pass can be used for VUID-StandaloneSpirv-VulkanMemoryModel-04678 and
VUID-StandaloneSpirv-VulkanMemoryModel-04679 (See "Standalone SPIR-V
Validation" section of Vulkan spec "Appendix A: Vulkan Environment for
SPIR-V").
Handle variables used by multiple entry points:
1. Update error check to make it working regardless of the order of
entry points.
2. For a variable, if it is used by two entry points E1 and E2 and
it needs the Volatile semantics for E1 while it does not for E2
- If VulkanMemoryModel capability is enabled, which means we have to
set memory operation of load instructions for the variable, we
update load instructions in E1, but do not update the ones in E2.
- If VulkanMemoryModel capability is disabled, which means we have
to add Volatile decoration for the variable, we report an error
because E1 needs to add Volatile decoration for the variable while
E2 does not.
For the simplicity of the implementation, we assume that all functions
other than entry point functions are inlined.
C++20 automatically adds reversed versions of operator overloads for
consideration; in this particular instance this results in infinite
recursion, which has now been pointed out elsewhere as a known issue
when migrating to C++20. Here we just disable one of the overloads in
C++20 mode and let the auto-reversing take care of it for us.
* linker: Address conversion error introduced in earlier rework
Also rework the code slightly to first compute the new ID bound and
validate it, and only then, offset all existing IDs.
This makes those two steps clearer, and avoids potentially overflowing
the IDs within a module (even if that would have been caught later on).
Fixes: c3849565 ("Linker improvements (#4679)")
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/4684
* test/linker: Disable IdsLimit tests for now
They are taking too long to run and results in the CI jobs timing out.
* test/linker: Code factorisation and small tweaks
* linker: Do not fail when going over limits
The limits are minima and implementations or APIs might support higher
limits, so just warn the user about it. And only check for the limits
right before emitting the binary, as limits might change earlier when
removing duplicate instructions, function prototypes, etc.
The only check performed right before merging, is making sure the ID
bound will not overflow the 32 bits following the merge.
Also, use the defines for the limits instead of hard-coding them.
* linker: Require a memory model in each input module
The existing code could run into weird situation. For example, if the
first module had no memory model, it would not emit any memory model
(sort of reasonable) and would accept without complains all possible mix
from later modules as it would not verify them.
* linker: Replace hex version with SPV_SPIRV_VERSION_WORD
* linker: Error out when linking together different versions
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/4135
* tools/linker: Do not write to disk if linking failed
Also, do not consider warnings as errors.
* tools/linker: Fix formatting in help message
* tools/linker: Further clarify the use of --target-env
Also update the text for the default version to reflect the change made
in 7d768812 ("Basic support for SPIR-V 1.6 (#4663)").
* PassManager: Print errors occurring during disassembly
Otherwise one could be greeted by the following text when running
spirv-opt withe the `--print-all` flag:
; IR before pass wrap-opkill
; IR before pass eliminate-dead-branches
; IR before pass merge-return
With this commit, one will instead get:
error: line 143: Invalid opcode: 400
warning: line 0: Disassembly failed before pass wrap-opkill
error: line 143: Invalid opcode: 400
warning: line 0: Disassembly failed before pass eliminate-dead-branches
error: line 143: Invalid opcode: 400
warning: line 0: Disassembly failed before pass merge-return
* PassManager: Use the right target environment when disassembling
Disassembly would fail if features from a newer version of SPIR-V than
1.2 were used.
The comment in `Array::GetExtraHashWords` is misleading because getting
the hash words is split up between the generic `Type::GetHashWords` and
the type specific `Type::GetExtraHashWords`. While `IsSameImpl` is
self-contained. Removing the comment since it is misleading and no
comment is really needed.
Fixes#3248
The test harness for the opt fuzzer was failing to consider that the
input might use a very large id bound, despite no id approaching this
bound actually being used.
This change modifies the test harness to use the module's id bound,
rather than looking through the module for large ids.
Fixes: oss-fuzz:42386
Ensures that instruction's opcode is set to something default when
parsing the module with --preserve-numeric-ids enabled. This avoids
uninitialized accesses and knock-on buffer overflows.
Fixes#4672.
For a shader input/output interface variable of structure type:
If the structure has BuiltIn members, then the structure type
must be Block decorated.
Otherwise, the variable, or the struct members must have locations,
but nothing can have both a location be a BuiltIn.

* Disallow conditional branch with duplicate labels

* Do not require the non-semantic extension after SPIR-V 1.5
The pass to remove the nonsemantic information and instructions
is used for drivers or tools that may not support them. Debug
information was only partially handle, which is causing a
problem. We need to either fully remove debug information or
not remove it all. Since I can see it being useful to keep the
debug information even when the nonsemantic instructions are
removed, I propose we do not remove debug info.
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/4269
In https://github.com/KhronosGroup/SPIRV-Tools/pull/3110, the strip reflect
pass was changed to also remove all explicitly nonsemantic instructions. This
makes it so that the name of the pass no longer reflects what the pass actually
does. This change renames the pass so that it reflects what the pass actaully does.
The upcoming spirv-diff tool also outputs disassembly, although in a
per-instruction basis. This change refactors the disassembler code to
support such a use case.
Use a very large id bound when fuzzing the optimizer, and check that the
input does not ids that are too close to this bound. This should make it
impossible in practice for an id overflow to occur.
Fixes#4657.
* detect iOS with CMAKE_SYSTEM_NAME

* Fix endianness of string literals
To get correct and consistent encoding and decoding of string literals
on big-endian platforms, use spvtools::utils::MakeString and MakeVector
(or wrapper functions) consistently for handling string literals.
- add variant of MakeVector that encodes a string literal into an
existing vector of words
- add variants of MakeString
- add a wrapper spvDecodeLiteralStringOperand in source/
- fix wrapper Operand::AsString to use MakeString (source/opt)
- remove Operand::AsCString as broken and unused
- add a variant of GetOperandAs for string literals (source/val)
... and apply those wrappers throughout the code.
Fixes #149
* Extend round trip test for StringLiterals to flip word order
In the encoding/decoding roundtrip tests for string literals, include
a case that flips byte order in words after encoding and then checks for
successful decoding. That is, on a little-endian host flip to big-endian
byte order and then decode, and vice versa.
* BinaryParseTest.InstructionWithStringOperand: also flip byte order
Test binary parsing of string operands both with the host's and with the
reversed byte order.
