Handle block-local names for Ada
GNAT can generate a mangled name with "B_N" (where N is a number) in the middle, like "hello__B_1__fourth.0". This is used for names local to a block. Multiple levels of block-local name can also occur, a possibility that was neglected by v1 of this patch. This patch changes gdb to handle these names. The wild name matcher is updated a straightforward way. The full matcher is rewritten. The hash function is updated to ensure that this works. This version does not seem to have the performance problems that affected v1. In particular, the previously-slow "bt" problem has been fixed. gdb/ChangeLog 2020-12-14 Tom Tromey <tromey@adacore.com> * dictionary.c (language_defn::search_name_hash): Ignore "B". * ada-lang.c (advance_wild_match): Ignore "B". (full_match): Remove. (do_full_match): Rewrite. gdb/testsuite/ChangeLog 2020-12-14 Tom Tromey <tromey@adacore.com> * gdb.ada/nested.exp: Add new tests. * gdb.ada/nested/hello.adb (Fourth, Fifth): New procedures.
