Some of the TC_START_LABEL implementations need to adjust the end of the symbol, when a colon doesn't mean a label definition. That means they need access to nul_char both the restore the NUL location (it may be a quote rather than a colon) and to store the new nul_char. Others need adjusting to step over a potential trailing quote. PR gas/18581 * config/tc-aarch64.h (TC_START_LABEL): Redefine. * config/tc-arm.c (tc_start_label_without_colon): Delete params.
