Condition coverage?

[gvl2023]

Looks like gcov can produce condition-coverage information (-fcondition-coverage, gcov --conditions), can it be shown in the lcov html report?

Current upstreamed version: no/not yet.
But probably fairly soon.

see sha 8f4d783

Note that this is tested only with gcc/14.2.0.
You can find an example in the 'example' directory (though this one is kind of bogus because all the expressions are trivial, so MC/DC and branch coverage are identical).

FWIW: TOT adds support for LLVM - tested with v18.1.3.
Please see the genhtml man page for a discussion of how MC/DC interpretation differs between gcc and llvm.
Testcase .../tests/lcov/mcdc illustrates some of those differences.
