commit r16-6089-gcca7c55cda3db8038f6e20e813ea8b17644531eb Author: Sandra Loosemore <[email protected]> Date: Fri Dec 5 17:07:27 2025 +0000 doc, microblaze: Clean up MicroBlaze option documentation [PR122243] gcc/ChangeLog PR other/122243 * config/microblaze/microblaze.opt (Zxl-mode-bootstrap): Mark as "Undocumented". (Zxl-mode-executable): Likewise. (Zxl-mode-novectors): Likewise. (Zxl-mode-xilkernel): Likewise. (Zxl-mode-xmdstub): Likewise. (mxl-stack-check): Likewise. (mno-clearbss): Likewise. (mxl-mode-executable): Make help string more useful. (mxl-mode-xmdstub): Likewise. (mxl-mode-bootstrap): Likewise. (mxl-mode-novectors): Likewise. (mxl-mode-xilkernel): Mark as "Undocumented". * doc/invoke.texi (Option Summary) <MicroBlaze Options>: Delete entries for obsolete options now explicitly undocumented, and add missing -mxl-prefetch option. (MicroBlaze Options): Add missing @opindex entries for negative option forms and list negative forms explicitly when appropriate. Delete documentation for obsolete/deprecated options. Add missing @opindex entries for the m[no-]xml-mode- options. Add missing documentation for -mxl-prefetch.
