-prof_genx

-prof_genx

I was searching for something like tcov to use on Itanium (in addiction to pfmon) and I was really very surprised when I 'uncovered' codecov which came with the Intel compiler 8.0. I failed to see any mentioning about it in the main documentation (except in the file list). After some digging I found an HTML page (/opt/intel/ntel_fc_80/doc/f_ug2/pgo_covr.htm). It turned out one needs to compile using -prof_genx to generate pgopti.spi file during compilation, then runthe compiled code to produce one or more *.dyn files. Then use profmerge on these *.dyn files (actually one is OK) to create pgopti.dpi file. Finally run
$ codecov -prj MyProj -counts
to produce a lot of useful information about the code.

However -prof_genx is never mentioned in Fortran for Linux documentation (except in the meta name contents of html files).

Is there anything else I've missed?

The code coverage tool (and test prioritization tool) is mentioned in the Release Notes.
