Hello,
I originally posted this on [llvm-dev] but this is hopefully more relevant.
I have an existing test suite I’m gathering coverage numbers for. I'm
getting 0% coverage with my C++ code, but the same setup works for C.
I've configured the build framework to set the compilation flags as follows:
clang++ -g -O2 -fprofile-arcs -ftest-coverage ...
The suite is a mixture of C and C++ code, and when I run lcov to generate a
report, the c++ tests are mostly reporting 0% coverage. I say mostly
because of static initializers being reported as ran once. The C tests
code correctly reports coverage for other shared libraries under test.
Here's my compiler version:
$ clang++ --version
clang version 3.9.1 (tags/RELEASE_391/final)
I'm wondering if there are any flags or debugging things I can instrument
with the c++ code to find out why the numbers aren't being recorded.
Any help would be appreciated, this is driving me nuts.
Thanks,
Patrick
