Tom Sepez 25390156 2025-08-21T00:13:19 Suppress unsafe buffers on a file-by-file basis in src/ [1 of N] In this CL, we suppress many files but stop short of actually enabling the warning by not removing the line from the unsafe_buffers_paths.txt file. That will happen in a follow-on CL, along with resolving any stragglers missed here. This is mostly a manual change so as to familiarize myself with the kinds of issues faced by the Angle codebase when applying buffer safety warnings. -- Re-generate affected hashes. -- Clang-format applied to all changed files. -- Add a few missing .reserve() calls to vectors as noticed. -- Fix some mismatches between file names and header comments. -- Be more consistent with header comment format (blank lines and trailing //-only lines when a filename comment adjoins license boilerplate).

Kimmo Kinnunen 12584049 2024-10-21T14:04:55 Make SimplifyLoopConditions testable Add ShCompileOptions::simplifyLoopConditions, so that tests can turn it on. Later edits to simplify loop condition logic are simpler to review when the testing related edits are landed separately. Test the feature by having ESSL as the input and ESSL as the natural output, to reflect how AST changes. To make the test expectations more deterministic across code changes, change SymbolTable::kLastBuiltInId to SymbolTable::kFirstUserDefinedSymbolId. This is simpler as no code needs to know exact last built in id, so we can just ensure that the user defined symbol ids do not clash with the builtin ids.

Shahbaz Youssefi ebe943e2 2021-07-29T11:19:33 Vulkan: SPIR-V Gen: Fix gl_Clip/CullDistance These built-ins can be redeclared in the shader. The translator took these redeclarations (and gl_LastFragData) as UserDefined symbols. There were a number of hacks such as in name generation and CollectVariables, to special-case these redeclarations. This change instead makes sure that these variables continue to be considered built-ins with the appropriate qualifiers. A number of fixes are made accordingly: - Hacks are removed. - In fragment shaders, ANGLEClipDistance was initialized with gl_ClipDistance for further use by the shader. The code generation however mistakenly produced `gl_ClipDistance[0] = ANGLEClipDistance[0];`, which caused compilation failures by glslang, but passed the tests accidentally because they expected link failures (see next item). - CollectVariables is fixed to correctly collect gl_Clip/CullDistance in fragment shaders; previously they were collected as output varyings, and therefore the aforementioned link error was not produced in the tests after the compilation error was fixed. Additional fixes: - The transformation of gl_Clip/CullDistance was always ever done on one of them due to misplaced breaks in the loop that detected their presence. - The transformation of gl_CullDistance was skipped when it was not redeclared. Validation is added to make sure these built-ins always have the correct qualifier even when redeclared. SPIR-V gen support for these variables have been fixed as well.

Olli Etuaho 94bbed1e 2018-03-20T14:44:53 Collect static use information during parsing We now collect metadata for variables in the symbol table. The metadata is stored in a map using the variable unique id as a key, so we can store the variables themselves as constexpr while still having dynamic metadata. For now we collect whether a variable is statically read or written. This can be used to more accurately determine whether a variable is statically used, but can also enable more optimizations in the future, such as pruning variables that are never read or folding variables that are never written after initialization. The collection is done during parsing, so that nothing is pruned from the AST before the static use is recorded. Static writes are flagged in ParseContext::checkCanBeLValue, as that function is already called for all variables that are written. Static reads are flagged whenever there's an operation that requires a variable to be read. This includes: * Unary and binary math ops * Comma ops * Ternary ops * Assignments * Returning the variable * Passing the variable as an in or inout argument to a function * Using the variable as a constructor argument * Using the variable as an if statement condition * Using the variable as a loop condition or expression * Using the variable as an index * Using the variable as a switch statement init expression In case there are statements that simply refer to a variable without doing operations on it, the variable is being treated as statically read. Examples of such statements: my_var; my_arr[2]; These are a bit of a corner case, but it makes sense to treat them as static use for validation purposes. Collecting correct static use information costs us a bit of compiler performance, but the regression is on the order of just a few percent in the compiler perf tests.

Olli Etuaho e600c0aa 2018-03-02T11:23:29 Use non-human-readable mangled names for types The new mangled name format is as follows: The first character is a hex digit from 0 to F that encodes vector or matrix size. For scalars, structs etc. the character is 0. Then, if it's a struct, the mangled name continues with "{s", followed by mangled names of fields, and ends with "}". If it's an interface block, the mangled name continues with "{i", followed by mangled names of fields, and ends with "}". If it's anything else, the second alphabetic character encodes the basic type. Characters are assigned to basic types in the enumeration order. If it's an array, the mangled name has a suffix [array_size]. This saves a few kilobytes from the binary size. The effect on symbol lookup speed seems mostly marginal.

Olli Etuaho 140152e7 2018-02-08T14:46:44 Statically allocate built-in function symbols A script gen_builtin_symbols.py now generates code for initializing built-in function symbols. The TFunction objects are initialized at C++ compile time. The source file used for the functions is in a format that's similar to how functions are given out in the GLSL spec, so it is easy to maintain. The function symbols are still inserted to the symbol table levels same as before. Getting rid of inserting the symbols at runtime is intended to be done as follow-up. This speeds up angle_unittests on Linux in release mode by a bit less than half, and in debug mode by more than half.

Olli Etuaho e5fe7aad 2018-01-29T12:06:11 Store builtin symbols as const pointers To do this we need two types of symbol table levels: A level for built-ins and a level for user-defined symbols. User-defined symbols are non-const because function symbols created based on function prototypes are changed when the function definition is parsed. On the other hand, we want to make built-in symbols constexpr, so we should only handle them through const pointers. This also gets rid of extra empty precision stack levels. Only one level is needed to store predefined precisions.

Olli Etuaho 2d8e432a 2018-01-22T14:12:46 Add ImmutableString to encapsulate some compiler strings The new ImmutableString class is intended to be used instead of plain const char pointers to pool-allocated or static memory. It has the following advantages over using plain const char pointers: 1. It makes it clear when a string is guaranteed to be safe to pass around inside the compiler. 2. It can be compared with a comparison operator rather than using strcmp, which is easier to read. 3. It records the length of the stored string, which enables faster copies and comparisons in some cases. 4. ImmutableStrings could be implicitly converted from std::strings when a pool-allocated string is required. This is robust and convenient. C++17 has a similar class std::string_view, but our code style doesn't allow it yet. We also couldn't use it as is if we require properties 1 and 4 from above, but would rather need to inherit or wrap it in a custom class. Eventually all current usage of TString could be replaced with ImmutableString. For now, use it for unmangled built-in names.

We also make sure that internal TFunctions added in traversers have correct parameter qualifiers. This makes TLValueTrackingTraverser much simpler. Instead of storing traversed functions or looking up builtin functions from the symbol table, determining which function parameters are out parameters can now be done simply by looking it up from the function symbol associated with the aggregate node. Symbol instances are no longer deleted when a symbol table level goes out of scope, and TFunction destructor no longer clears the parameters. They're all either statically allocated or pool allocated, so this does not result in leaks.

Olli Etuaho 2d88e9bc 2017-07-21T16:52:03 Guarantee that symbol nodes get unique ids The code is refactored so that symbol nodes can only be initialized with an unique id object. This prevents accidentally forgetting to create an id for a symbol node. This opens up possibilities for future optimization: For example the names and types of symbols could be stored in a central location inside the SymbolTable, and TIntermSymbol nodes would only need to store the symbol id. The symbol id could be used to look up the name and type of the node.

Olli Etuaho fe48632f 2017-03-21T09:30:54 Prefer identifying functions by using symbol ids The shader translator code is now structured in a way that ensures that all function definition, function prototype and function call nodes store the integer symbol id for the function. This is guaranteed regardless of whether the function node is added while parsing or as a result of an AST transformation. TIntermAggregate nodes, which include function calls and constructors can now only be created by calling one of the TIntermAggregate::Create*() functions to ensure they have all the necessary properties. This makes it possible to keep track of functions using integer ids instead of their mangled name strings when generating the call graph and when using TLValueTrackingTraverser. This commit includes a few other small cleanups to the CallDAG class as well.

Olli Etuaho 1ecd14b8 2017-01-26T13:54:15 Fold user-definedness of function nodes into TOperator Whether a function call is user-defined is not orthogonal to TOperator associated with the call node - other ops than function calls can't be user-defined. Because of this it makes sense to store the user- definedness by having different TOperator enums for different types of calls. This patch also tags internal helper functions that have a raw definition outside the AST with a separate TOperator enum. This way they can be handled with logic that is easy to understand. Before this, function calls like this left the user-defined bit unset, despite not really being built-ins either. The EmulatePrecision traverser uses this. This is also something that could be used to clean up built-in emulation in the future.
