--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:e543eaa671d40868575385360d13ef37d87fb2a0 commit r16-188-ge543eaa671d40868575385360d13ef37d87fb2a0 Author: Richard Biener <rguent...@suse.de> Date: Tue Feb 18 12:52:34 2025 +0100 middle-end/60779 - LTO vs. -fcx-fortran-rules and -fcx-limited-range The following changes how flag_complex_method is managed towards being able to record that in the optimization set so we can stream and restore it per function. Currently -fcx-fortran-rules and -fcx-limited-range are separate recorded options but saving/restoring does not restore flag_complex_method which is later used in the middle-end. The solution is to make -fcx-fortran-rules and -fcx-limited-range aliases of a new -fcx-method= switch that represents flag_complex_method directly so we can save and restore it. PR middle-end/60779 * common.opt (fcx-method=): New, map to flag_complex_method. (Enum complex_method): New. (fcx-limited-range): Alias to -fcx-method=limited-range.
