Option Description
-fcfgo-profile-generate[=path]
This option builds upon the optimization enabled by the -fprofile-generate option and fine-tunes certain parameters using AI4Compiler to aim for superior performance. The path must be specified.
-fprofile-correction
This option employs heuristics for error correction and smoothing to correct inconsistencies in the profile feedback data.
-Wno-coverage-mismatch
By default, profile mismatches with the source code are treated as errors. This option downgrades such errors to warnings, recommended only for situations with minimal code changes, particularly in cold code paths.
-fcfgo-profile-use[=path]
This option uses profiles stored in the specified path to guide the compiler for optimization. It must be used together with -fcfgo-profile-generate.
