--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by kishan parmar <[email protected]>: https://gcc.gnu.org/g:81eff4e45599838612422bd429845ba0117bd7f3 commit r16-9660-g81eff4e45599838612422bd429845ba0117bd7f3 Author: Kishan Parmar <[email protected]> Date: Wed Sep 2 12:10:30 2026 +0530 configure: reject unsupported --with-long-double-64 option [PR122535] Configure script previously accepted unsupported --with-long-double-64 option without any warning, leading to confusion. This option was mistakenly documented in install.texi but never handled by configure script, resulting in it being silently ignored. Patch updates configure script to error out when --with-long-double-64 or --without-long-double-64 is used, and instructs to use the correct --without-long-double-128 or --with-long-double-128 option instead. Additionally, the mistaken documentation reference in install.texi has been corrected to reflect the actual supported option. 2026-09-02 Peter Bergner <[email protected]> ChangeLog: PR target/122535 * configure.ac: Error out on --with-long-double-64. * configure: Regenerate. gcc/ChangeLog: * doc/install.texi: Remove incorrect mention of --with-long-double-64. Co-authored-by: Kishan Parmar <[email protected]> (cherry picked from commit 0367500f385f57f93e01e09b27b0a3b3c7695dd6)
