It could either: > (a) don't attempt to store location ranges (would probably have to disable > e.g. fix-it hints) > (b) set line_table->default_range_bits to 0, so that all ranges have to go > to the ad-hoc table, but buying space for more locations. > Hi, David, I have sent a Patch review request to you (Cc'ing gcc-patc...@gcc.gnu.org) on 4/3/2020. this patch is per your above approach b. please take a look and let me know your opinion on it.
