// Array listing regular expressions of paths that should be ignored when
// running the rewrite_raw_ptr_fields tool on Chromium sources.
//
// If a source file path contains any of the lines in the filter file below,

//
// Lines prefixed with "!" can be used to force include files that matched a
// file path to be ignored.
//
// Note that the rewriter has a hardcoded logic for a handful of path-based
// exclusions that cannot be expressed as substring matches:
// - Excluding paths containing "third_party/", but still covering
// "third_party/blink/"
// (see the isInThirdPartyLocation AST matcher in RewriteRawPtrFields.cpp).
// - Excluding paths _starting_ with "gen/" or containing "/gen/"
// (i.e. hopefully just the paths under out/.../gen/... directory)
// via the isInGeneratedLocation AST matcher in RewriteRawPtrFields.cpp.
