AFLGo Link-Time Instrumentation

include/Fuzzing/AFLGoLinker/ and lib/Fuzzing/AFLGoLinker/ implement the link-time instrumentation passes for AFLGo-style directed fuzzing.

Location: include/Fuzzing/AFLGoLinker/, lib/Fuzzing/AFLGoLinker/

Main passes:

• AFLGoDistanceInstrumentationPass instruments distance feedback.

• FunctionDistancePass injects function-level distance data.

• DAFLInstrumentationPass adds DAFL-specific instrumentation.

• DuplicateTargetRemovalPass and AFLGoTargetInjectionFixupPass clean up target metadata before final code generation.

Role in the pipeline:

• consume the analyses from Directed Fuzzing Analyses

• insert profile-guiding feedback at LTO time

• finalize target handling for directed greybox fuzzers
