Tool to diff lcov files
USAGE:
lcov-diff [FLAGS] [OPTIONS] <FILE1> <FILE2>
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
-v, --verbose Show Debug logging
OPTIONS:
-o, --output <PATH> output file to write (stdout if not presented)
-w, --web <web> Generate html report from output file (default name web)
ARGS:
<FILE1> <FILE2> Files to process, right now just two of them
The output file contains the only lines/functions/basic blocks which are presented only in the first lcov file.
To generate html report for the diff use genhtml tool
, see.
lcov-diff first.info second.info -o out.info
genhtml --ignore-errors source -o web out.info
Or just run with -w
/--web
option to generate it automatically after getting diff file
(if output
is not set a tmp file will be used for it).
The default output directory name is web
.
Also, it gets into panic if genhtml
could not be invoked.
lcov-diff first.info second.info -w LCOV_HTML_DIR -o out.info
