- We have recently been evaluating a commercial tool that will instrument BOTH
- Fortran and C source for test-coverage measurements. Unfortunately, this
- tool has proved unacceptable, for many reasons but particularly for the
- incredibly high overhead of running the instrumented code -- would you
- believe TWENTY TIMES SLOWER (yes, not 20 PERCENT, 20 TIMES) for instrumenting
- modules worth about 2,000 lines out of a 100,000 lines program?! Ok, they
- were the lowest-level modules, but even so.
-
- I am aware of several C-only tools of various description, but I've been
- asked to check if there's any tool that will be able to handle both C and
- Fortran sources in the same program -- many of our programs are like that,
- so that having a C-only tool would not be very comfortable (yup, we could
- convert fortran-> via f2c or similar, but then the modules' authors would
- have to interpret the coverage results in C-source terms rather than in
- Fortran terms, and they may not be familiar with C, etc etc).
-
- I will appreciate any info/suggestion, either posted or via email; I will
- of course post a summary of emailed info if requested to do so. Thanks.
