In the gfortran compiler gcov allows the developer to determine how many times each line has executed in a program. For instance if i have a do loop, the instrumented code run shows me how many times the lines within the loop have been executed.
Is it possible to do the same in ifort? I get the color coded coverage and that's nice, but I need quantitative information about how many times all my lines have run, and then I'd like to sift through them to see which ones are running the most times.
Also, is it possible to instrument code such that I can query it after a run? I've heard code coverage outputs html and xml files. Is it possible to query, for instance, the xml file to do some proper reflection/instrospection/code analysis? Like for example returning all derived types in my code, all global variables, lines which have run above a certain number of times etc.
Allright so I figured out how to include execution count information under Tools>Intel Composer > Settings> Show Execution Counts to TRUE
I still don't understand the numbers that are coming up on my coverage report. Here's some sample code
Do i=1,LT ^ 8,842 (2/3) 264) C=Tmp(i:i) ^ 16,916 (2/3) ^ 59,206 (7/14) 265) j=ichar(c) ^ 8,458 266) If (j.Ge.97.And.j.Le.122) Then ^ 8,458 (1/2) 267) Tmp(i:i)=Char(j-32) ^ 0 (13) ^ 0 (3) 268) End If 269) End Do
What do the numbers mean? Specifically the number after the ^ symbol and the numbers in parentheses. Why are the numbers in parentheses sometimes fractions?
