Fangrui Song	8cf1ac97ce	[llvm-cov gcov] Improve accuracy when some edges are not measured ... Also guard against infinite recursion if GCOV_ARC_ON_TREE edges contain a cycle.	2020-09-12 22:33:41 -07:00
Fangrui Song	e3200dab60	[gcov] Support .gcno/.gcda in gcov 8, 9 or 10 compatible formats	2020-06-07 11:27:49 -07:00
Fangrui Song	e664d0543f	[gcov] Improve tests and lower the minimum supported version to gcov 3.4 ... global-ctor.ll no longer checks what it intended to check (@_GLOBAL__sub_I_global-ctor.ll needs a !dbg to work). Rewrite it. gcov 3.4 and gcov 4.2 use the same format, thus we can lower the version requirement to 3.4	2020-06-06 23:11:32 -07:00
