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

These are not called/referenced by anything, and are marked as being
unused. They were brought to my attention by a coverity based bug
report.
Fixes#2537
This is required to properly handle uses of forward declared ids. Since forward
declared ids were not being properly covered by the validator this uncovered a
bunch of small issues that needed to be resolved to get tests passing again.
Fixes#2373
This CL changes the id/name output from the validator to always use a
consistent id[%name] style. This removes the need for getIdOrName. The
name lookup is changed to use the NameMapper so the output is consistent
with what the disassembler will produce.
Fixes#2137

* Don't free diagnostics in spvBinaryParse
* When invoking the parser we wish to ignore the error messages from,
instead create a hijacked context and replace the message consumer with
a null consumer
* Validate the id bound.
Validates that the id bound for the module is not larger than the max id
bound. Also adds an option to set the max id bound. Allows the
optimizer option to set the max id bound to also set the id bound for
the validation run done by the optimizer.
Fixes#2030.
This commit will change the message for unknown extensions from an error
to a warning.
Code was added to limit the number of warning messages so that consummer
of the messages are not overwhelmed. This is standard practice in
compilers.
Many other issues were found at while looking into this. They have been
documented in #1950.
Fixes http://crbug.com/875547.
OpPhi instruction must appear before all non-OpPhi instructions
except for OpLine. Without this commit, Validator does not check
the case that an OpPhi is preceeded by an OpLine and the OpLine is
preceeded by a non-OpPhi instruction that is not OpLine.
* Split constant opcode validation out of idUsage and into
validate_constants.cpp
* minor style fixes
* reduced duplication
* fixed an issue with array sizing
When doing the validator checks, an instruction is currently registered
at the end of IdPass. This creates an inconsistency. In IdPass, an
instruction that uses its own result will treat that use as a forward
reference. Then in the following passes it will not because the
definition can be found.
It seems best to update the state after all of the check have been done
for the current instruction. This makes it consistent for all of the
passes.
This makes a different when trying to verify OpTypeStruct.
Fixes https://crbug.com/874372.
* Moved function opcode validation out of idUsage and into new files
* minor style changes
* General opcode checking is in validate_function.cpp
* Execution limitation checking is in
validate_execution_limitations.cpp
* Execution limitations was split into a new pass as it requires other
validation to register those limitations first.
* Changed entry point validation to check storage class of variable
instead of pointer
* added a test
* Moved several checks after opcode validation
* These checks should be able to guarantee individual instructions are
ok
* Updated tests due to reordered checks
* Moved type instruction validation out of validation idUsage into a new
file
* Consolidate type unique pass into new file
* Removed one bad test
* Reworked validation ordering
* Replaced uses in opcode validation of current_function()
* Added non-const accessor to function lookup in ValidationState_t
* Updated a couple bad tests due to check reordering
When validating a FunctionCall we can trigger an assert if we are not
currently within a function body. This CL adds verification that we are
within a function before attempting to add a function call.
Issue 1789.
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 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 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.
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 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.
