slang::analysis::AnalysisManager class
#include </home/runner/work/slang/slang/include/slang/analysis/AnalysisManager.h>

The analysis manager coordinates running various analyses on AST symbols.

Analysis is done downstream from one or more Compilation objects. Once a design has an AST successfully built, analysis passes can be run to check for various issues or extract information.

Constructors, destructors, conversion operators

AnalysisManager(AnalysisOptions options = {}) explicit: Default constructor for the analysis manager.

Public functions

auto getOptions() const -> const AnalysisOptions&: Gets the set of options used to construct the analysis manager.
auto hasFlag(bitmask<AnalysisFlags> flags) const -> bool: Returns true if the given flag(s) are enabled for this analysis.
auto analyze(const ast::Compilation& compilation) -> AnalyzedDesign: Analyzes the given compilation and returns a representation of the design.
auto getDrivers(const ast::ValueSymbol& symbol) const -> DriverList: Returns all of the known drivers for the given symbol.
auto getDiagnostics(const SourceManager* sourceManager) -> Diagnostics: Collects and returns all issued analysis diagnostics.
auto analyzeScopeBlocking(const ast::Scope& scope, const AnalyzedProcedure* parentProcedure = nullptr) -> const AnalyzedScope&: Analyzes the given scope, in blocking fashion.
auto getAnalyzedScope(const ast::Scope& scope) const -> const AnalyzedScope*: Returns the results of a previous analysis of a scope, if available.
auto getAnalyzedSubroutine(const ast::SubroutineSymbol& symbol) const -> const AnalyzedProcedure*: Gets the result of analyzing a subroutine, if available.
auto addAnalyzedSubroutine(const ast::SubroutineSymbol& symbol, std::unique_ptr<AnalyzedProcedure> procedure) -> const AnalyzedProcedure*: Adds a new analyzed subroutine to the manager's cache for later lookup.

Function documentation

AnalyzedDesign slang::analysis::AnalysisManager::analyze(const ast::Compilation& compilation)

Analyzes the given compilation and returns a representation of the design.

Diagnostics slang::analysis::AnalysisManager::getDiagnostics(const SourceManager* sourceManager)

Collects and returns all issued analysis diagnostics.

If sourceManager is provided it will be used to sort the diagnostics.

const AnalyzedScope& slang::analysis::AnalysisManager::analyzeScopeBlocking(const ast::Scope& scope, const AnalyzedProcedure* parentProcedure = nullptr)

Analyzes the given scope, in blocking fashion.

const AnalyzedProcedure* slang::analysis::AnalysisManager::getAnalyzedSubroutine(const ast::SubroutineSymbol& symbol) const

Gets the result of analyzing a subroutine, if available.

Otherwise returns nullptr.
