Summary: Possible coverage levels are: * -fsanitize-coverage=func - function-level coverage * -fsanitize-coverage=bb - basic-block-level coverage * -fsanitize-coverage=edge - edge-level coverage Extra features are: * -fsanitize-coverage=indirect-calls - coverage for indirect calls * -fsanitize-coverage=trace-bb - tracing for basic blocks * -fsanitize-coverage=trace-cmp - tracing for cmp instructions * -fsanitize-coverage=8bit-counters - frequency counters Levels and features can be combined in comma-separated list, and can be disabled by subsequent -fno-sanitize-coverage= flags, e.g.: -fsanitize-coverage=bb,trace-bb,8bit-counters -fno-sanitize-coverage=trace-bb is equivalient to: -fsanitize-coverage=bb,8bit-counters Original semantics of -fsanitize-coverage flag is preserved: * -fsanitize-coverage=0 disables the coverage * -fsanitize-coverage=1 is a synonym for -fsanitize-coverage=func * -fsanitize-coverage=2 is a synonym for -fsanitize-coverage=bb * -fsanitize-coverage=3 is a synonym for -fsanitize-coverage=edge * -fsanitize-coverage=4 is a synonym for -fsanitize-coverage=edge,indirect-calls Driver tries to diagnose invalid flag usage, in particular: * At most one level (func,bb,edge) must be specified. * "trace-bb" and "8bit-counters" features require some level to be specified. See test case for more examples. Test Plan: regression test suite Reviewers: kcc Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D9577 llvm-svn: 236790
