I don't see how the current code can possibly work with -fcompare-debug. For
the sake of completeness, here's the code whose removal is problematic/wrong:
- /* Don't allow debug stmts to affect discriminators, but
- allow them to take discriminators when they're on the
- same line as the preceding nondebug stmt. */
- if (is_gimple_debug (stmt))
- {
- if (curr_locus != UNKNOWN_LOCATION
- && same_line_p (curr_locus, &curr_locus_e,
- gimple_location (stmt)))
- {
- location_t loc = gimple_location (stmt);
- location_t dloc = location_with_discriminator (loc,
- curr_discr);
- gimple_set_location (stmt, dloc);
- }
- continue;
- }
