This CL moves most of the logic out of validation ProcessInstruction and
groups it into validate. This places all of the validation logic in the
same place making it clearer what is running.
The Instruction class is changed to allow setting the function and block
after creation.
This CL changes the stats aggregator to use
ValidateBinaryAndKeepValidationState to process the binary. This means
we can remove ValidateInstructionAndUpdateValidationState which expects
to be able to call ProcessInstruction in the validate anonymous
namespace. This decouples the stats aggregator from how validation
processes the binary.
The instruction counter is the same as the size of the
ordered_instruction list when we insert a new instruction. This Cl
removes instruction_counter_ and uses that instead.
* Refactored the Memory class of instructions in the spec out Id
validation and into a new pass
* Tests unmodified
* some minor disassembly changes
* minor style changes
Many of the files have using std::<foo> statements in them, but then the
use of <foo> will be inconsistently std::<foo> or <foo> scattered
through the file. This CL removes all of the using statements and
updates the code to have the required std:: prefix.
This CL removes the two diag() overloads and leaves only the version
which accepts an Instruction. This is safer as we never use the
implicit location from the validation state.
Several of the diag() calls in validate_decorations do not provide the
line number, and will output the last line in the file. This CL updates
the diag() calls to provide the instruction of interest.
This CL removes the two deque's from ValidationState and converts them
into std::vectors. In order to maintain the stability of instructions we
walk over the binary and counter the instructions and functions in the
ValidationState constructor and reserve the required number of items in
the module_functions_ and ordered_instructions_ vectors.
Issue #1176.
This CL updates the diag() calls in validate_cfg to provide the
associated instruction. This fixes a couple places where we output the
last line of the file instead of the instruction as the disassembly.
Previously the adjacency messages would output the last line of the file
as the disassembly. This is incorrect, as we have an instruction they
can be attached too. This CL fixes the messages to attach to the correct
line number.
This CL changes validate.cpp to use diag providing an explicit
instruction. This changes the result of the function end checks to not
output a disassembly anymore as printing the last line of the module
didn't seem to make sense.
This CL changes the signature of diag() to accept an Instruction instead
of the instructions position.
A deprecated variant that accepts the position is available but will be
removed in the near future.
Currently, some instructions will be missing from the list of
ordered_instructions. This will cause issues due to the debug change
which passed the last instruction into subsequent passes.
This CL moves the addition to the ordered list out of the
RegisterInstruction method into AddOrderedInstruction. This method is
called first in ProcessInstruction and the CapabilitiesPass and IdPass
are updated to take an Instruction parameter.
This CL removes the redundant operator name from the error messages in
validate_composites. The operator will be printed on the next line with
the disassembly.
This CL splits the switch in ImagePass into individual validate
functions. The error messages have been updated to drop the
suffix/prefix of the opcode name since it will be displayed in the
disassembly.
This CL updates the code to pull a valid instruction for the line number
when outputting a component error in OpVectorShuffle. The error line
isn't the best at this point as it points at the component, but it's
better then a -1 (turning to max<size_t>) that was being output.
The error messages has been updated to better reflect what the error is
attempting to say.
Issue 1719.
When folding a vector shuffle that feeds another vector shuffle causes
the size of the first operand to change, when other indices have to be
adjusted reletive to the new size.
- Vulkan 1.0 uses strict layout rules
- Vulkan 1.0 with relaxed-block-layout validator option
enforces all rules except for the relaxation of vector
offset.
- Vulkan 1.1 and later always supports relaxed block layout
Add spot check tests for the relaxed-block-layout scenarios.
Fixes#1697
This CL moves the various validate files into the val/ directory with
the rest of the validation infrastructure. This matches how opt/ is
setup with the passes with the infrastructure.
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.
Fixes#1685
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.
- Add asm/dis test for SPV_KHR_8bit_storage
- validator: SPV_KHR_8bit_storage capabilities enable declaration of 8bit int
TODO:
- validator: ban arithmetic on 8bit unless Int8 is enabled
Covered by https://github.com/KhronosGroup/SPIRV-Tools/issues/1595
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
