Fortran Coverage Analysis Tool (FCAT)

Finds "cold-spots" in Fortran codes (the part of the codes that are never executed), and flags these parts line-by-line. Finds "hot-spot" in Fortran codes (the part of the codes that are most frequently executed), and gives a line by line profile. Designed to working mainly with Fortran 90 and 95, but also works with fixed format code, and thus Fortran 77. [Free]
