Martin Liška <marxin at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |INVALID --- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> --- Ok, so apparently it's fine, note that we build libiberty twice (once in pic subfolder) and it looks some files are used only in of of these. Some files in libiberty have no coverage, e.g. : ../../libiberty/fdmatch.c:68:1: warning: ‘/home/mliska/Programming/gcc/objdir/libiberty/fdmatch.gcda’ profile count data file not found [-Wmissing-profile] ../../libiberty/fdmatch.c:68:1: warning: ‘/home/mliska/Programming/gcc/objdir/libiberty/pic/fdmatch.gcda’ profile count data file not found [-Wmissing-profile] For zlib and lto there's no coverage in train run. And gcc/gen*.c files are ok as these are used only in build, not in a built compiler. Thus closing..
