Description Hongtao Liu 2023-05-22 02:03:54 UTC

Some users found the -mdaz-ftz option to be very useful, so I've backported the commit from main trunk to GCC 12 release branch:
r12-9536-gefcca6481eab18 and GCC 11 release branch: r11-10764-g003f9ab9e909a7

I also hope to downstream the patch to next GTS12/DTS12 and Rel9 system compiler GCC 11 release.

Releted GCC mail thread in https://gcc.gnu.org/pipermail/gcc-patches/2023-May/617425.html

Comment 1 Marek Polacek 2023-05-22 15:08:42 UTC

This should be part of the rebase to GCC 11.4.

Not plans to backport to GTS 12 gcc at this point.

Comment 2 Hongtao Liu 2023-05-23 03:45:22 UTC

Do we have GTS13 on Rel8?
