Detailed Description

CodeGenOptions - Track various options which control how the code is optimized and passed to the backend.

Member Enumeration Documentation

Enumerator
NoDebugInfo 
LocTrackingOnly 

Don't generate debug info.

DebugLineTablesOnly 

Emit location information but do not generate debug info in the output. This is useful in cases where the backend wants to track source locations for instructions without actually emitting debug info for them (e.g., when -Rpass is used).

LimitedDebugInfo 

Emit only debug info necessary for generating line number tables (-gline-tables-only).

FullDebugInfo 

Generate complete debug info.

Limit generated debug info to reduce size (-fno-standalone-debug). This emits forward decls for types that could be replaced with forward decls in the source code. For dynamic C++ classes type info is only emitted int the module that contains the classe's vtable.

std::shared_ptr<llvm::Regex> clang::CodeGenOptions::OptimizationRemarkAnalysisPattern

Regular expression to select optimizations for which we should enable optimization analyses. Transformation passes whose name matches this expression (and support this feature), will emit a diagnostic whenever they want to explain why they decided to apply or not apply a given transformation. This is enabled by the -Rpass-analysis=regexp flag.

Transformation passes whose name matches this expression (and support this feature), will emit a diagnostic whenever they tried but failed to perform a transformation. This is enabled by the -Rpass-missed=regexp flag.
