--- Comment #22 from Georg-Johann Lay <gjl at gcc dot gnu.org> --- On v13.5, v14.4 and v15.3+ -ftree-switch-conversion is disabled by default now. A target hook to put the CSWTCH tables into a named address-space hase been rejected several times for non-technical reasons. Thus kick out such tables altogether until a better solution.
