How to enable coverage option in the latest drop of clang/llvm

[Sinha, Prokash]

Can someone please enlighten me on this…

__ The freebsd10 stable does not have the —coverage option working.  Whereas mac X with Xcode handles this as per my experiment.

__ So I should have some flags or something from the configure options that I can use to have this enabled.

If not, then please help me understand this.

Thanks

Hi All,

Initially I was having problem compiling clang/llvm, then found some of the compilation error.

Now I can build it on freebsd 10.

But I need to have the coverage option on.  On Mac it is still there -

bash$ clang --coverage main.c  -###
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
