Constructor & Destructor Documentation

◆ PipelineTuningOptions()

PipelineTuningOptions::PipelineTuningOptions ( )

Constructor sets pipeline tuning defaults based on cl::opts.

Each option can be set in the PassBuilder when using a LLVM as a library.

Member Data Documentation

◆ CallGraphProfile

bool llvm::PipelineTuningOptions::CallGraphProfile

Tuning option to enable/disable call graph profile.

Its default value is that of the flag: -enable-npm-call-graph-profile.

Definition at line 111 of file PassBuilder.h.

Referenced by PipelineTuningOptions().

◆ Coroutines

bool llvm::PipelineTuningOptions::Coroutines

Tuning option to enable/disable coroutine intrinsic lowering.

Its default value is false. Frontends such as Clang may enable this conditionally. For example, Clang enables this option if the flags -std=c++2a or above, or -fcoroutines-ts, have been specified.
