NAME

       cg_diff - compares two Cachegrind output files

SYNOPSIS

       cg_diff [options] cachegrind-out-file1 cachegrind-out-file2

DESCRIPTION

       cg_diff takes two output files produced by the Valgrind tool Cachegrind, computes the
       difference and prints the result in the same format that Cachegrinds outputs.

OPTIONS

       -h --help
           Show the help message.

       --version
           Show the version number.

       --mod-filename=<expr> [default: none]
           Specifies a Perl search-and-replace expression that is applied to all filenames.
           Useful for removing minor differences in paths between two different versions of a
           program that are sitting in different directories.

       --mod-funcname=<expr> [default: none]
           Like --mod-filename, but for filenames. Useful for removing minor differences in
           randomized names of auto-generated functions generated by some compilers.
