Subject: Fixed code coverage checking
X-Git-Url: https://git.codecow.com/?a=commitdiff_plain;h=34a74eba09f61c4e83cd8ee5304122030eeff264;p=Monocypher.git

Fixed code coverage checking

Fixed #47

The manual was missing the `-fcoverage-mapping` option, of course we
didn't have coverage data...

Also changed `llvm-cov` to `llvm-cov-3.8` on tests/coverage.sh: some
systems don't have the versionless alias.
