[LLVMdev] Meaning of llvm-cov 'taken at least once'

[George King]

Hi list,
Today I played around with the llvm-cov from the 3.5rc3 release; here
is an example of output:

Function 'main'
Lines executed:91.67% of 24
Branches executed:100.00% of 11
Taken at least once:81.82% of 11
No calls

What is the meaning of 'branches executed' versus 'taken at least
once'? I would imagine that the first implied the second, so I'm
clearly missing something.

Also, what is the alternative to 'no calls'? I see that in every
function in my single-file example; does it mean calls across
compilation units?

Thanks,
George
