Parts: - Hpc.[ch] - small runtime support for Hpc; reading/writing *.tix files. - Coverage.lhs - Annotates the HsSyn with coverage tickboxes. - New Note's in Core, - TickBox -- ticked on entry to sub-expression - BinaryTickBox -- ticked on exit to sub-expression, depending -- on the boolean result. - New Stg level TickBox (no BinaryTickBoxes, though) You can run the coverage tool with -fhpc at compile time. Main must be compiled with -fhpc.
