fprofile-dwo-dir
Specifies the directory where .dwo files should be stored when using options fprofile-sample-generate and gsplit-dwarf. This is an experimental feature.
fprofile-ml-use
Enables the use of a pre-trained machine learning model to predict branch execution probabilities driving profile-guided optimizations.
fprofile-sample-generate
Enables the compiler and linker to generate information and adjust optimization for Hardware Profile-Guided Optimization (HWPGO).
fprofile-sample-use
Enables the compiler and linker to use information for Hardware Profile-Guided Optimization (HWPGO). This is an experimental feature.
