--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.
