1.
BUILD.gn: Don't use the extra Chromium clang warnings
Also removes the unused .gn secondary_sources.
2.
Move fuzzers in test/ instead of testing/
This frees up testing/ to be the git subtree of Chromium's src/testing/
that contains test.gni, gtest, gmock and libfuzzer
3.
DEPS: get the whole testing/ subtree of Chromium
4.
BUILD.gn: Simplify the standalone gtest targets
These targets definitions are inspired from ANGLE's and add a variable
that is the path of the googletest directory so that it can be made
overridable in future commits.
6.
BUILD.gn: Add overridable variables for deps dirs
This avoids hardcoded paths to dependencies that make it hard to
integrate SPIRV-Tools in other GN projects.
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.
The spirv-opt fuzzer is not registering any passes to run, so it is not
currently testing anything. For now we will just register the
performance passes.
We should add different fuzzers for the legalization pass
(RegisterLegalizationPasses()), and the size passes
(RegisterSizePasses()).
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.
In the merge return pass, we will split a block, but not update the phi
instructions that reference the block. Since the branch in the original
block is now part of the block with the new id, the phi nodes must be
updated.
This commit will change this.
I have also considered other places where an id of a basic block could
be referenced, and I don't think any of them need to change.
1) Branch and merge instructions: These jump to the start of the
original block, and so we want them to jump to the block that uses the
original id. Nothing needs to change.
2) Names and decorations: I don't think it matters with block keeps the
name, and there are no decorations that apply to basic blocks.
Fixes#1736.
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.
The SPIRV-Tools target doesn't build anything, it just depends on the other libraries. As such, there is no static_library generated and this should be a group() instead.
When creating a new phi for a value in the function, merge return will
rewrite all uses of an id that are no longer dominated by its
definition. Uses that are not in a basic block, like OpName or
decorations, are not dominated, but they should not be replaced.
Fixes#1736.
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.
* Combines OpAccessChain, OpInBoundsAccessChain, OpPtrAccessChain and
OpInBoundsPtrAccessChain
* New folding rule to fold add with 0 for integers
* Converts to a bitcast if the result type does not match the operand
type

This CL moves the SPIRV_TIMER_ENABLED preprocesser guard to encompass
the includes along with the source. Currently we will try to pull in
sys/resource.h on machines which may not have the file available and the
build will fail. If we don't need timers, then we don't need the
includes as well.
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.
