cg_diff — compares two Cachegrind output files

--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.
