Fangrui Song 789e9aff28 [llvm-cov gcov] Compute unmeasured arc counts by Kirchhoff's circuit law ... For a CFG G=(V,E), Knuth describes that by Kirchoff's circuit law, the minimum number of counters necessary is |E|-(|V|-1). The emitted edges form a spanning tree. libgcov emitted .gcda files leverages this optimization while clang --coverage's doesn't. Propagate counts by Kirchhoff's circuit law so that llvm-cov gcov can correctly print line counts of gcc --coverage emitted files and enable the future improvement of clang --coverage.		2020-09-08 18:45:11 -07:00
