Itanium IA-64 Support May Revert Back To Being Deprecated/Obsolete For GCC 16
The GCC 14 compiler had marked the Itanium IA-64 code as being obsolete and slated for removal in GCC 15
As there hasn't been a full GCC test suite run in one year and falling behind in supporting other GCC features compared to other CPU architectures, marking Itanium IA-64 as obsolete is back to being talked about. Plus hardware is increasingly rare, there are no Itanium build bots for the GCC compiler, and user-mode emulation of IA-64 is slow and incomplete. Beyond the lack of build bots / IA-64 hardware access and no formal maintainer of the GCC Itanium code, this post in the thread outlines some of the limitations of the IA-64 code due to it not being actively maintained.
