This program assumes 15 that the description and data file uses same format as gcov files. 16 17 =head1 OPTIONS 18 19 =over 20 21 =item B<-gcno=filename] 22 23 This option selects input description file generated by compiler while instrumenting 24 program. 25 26 =item B<-gcda=filename] 27 28 This option selects coverage data file generated by instrumented compiler. 29 30 =item B<-dump> 31 32 This options enables output dump that is suitable for a developer to help debug 33 B<llvm-cov> itself. 34 35 =back 36 37 =head1 EXIT STATUS 38 39 B<llvm-cov> returns 1 if it cannot read input files. Otherwise, it exits with zero. 40 41 =head1 AUTHOR 42 43 B<llvm-cov> is maintained by the LLVM Team (L<http://llvm.org/>). 44 45 =cut 46
