2175 | ||
2176 | Function called by C<do_readline> to spawn a glob (or do the glob inside | |
2177 | perl on VMS). This code used to be inline, but now perl uses C<File::Glob> | |
210b36aa | 2178 | this glob starter is only used by miniperl during the build process. |
0d44d22b | 2179 | Moving it away shrinks pp_hot.c; shrinking pp_hot.c helps speed perl up. |
