Hey there, I wanted to come back to maintaining the ia64 port as discussed preciously the other month on the gcc list.
It has been some days as we were busy releasing the biggest release of our Embdded T2/Linux distribution [0] and we obviously did not want to propose to enable LRA for IA-64 in the last last days of the gcc 14 release process. We used the time to further stability test the LRA enabled GCC built in T2/Linux and set up running the GCC testsuite accordingly for which Frank posted test results from GCC git for reference [1] and w/ LRA [2] enabled with only minimal changes, but also some new testsuite passes. Due to the -j4 run I summed up the text files result manually in LibreOffice: gcc 35572, 31789 33273, 28492 37189, 36804 28735, 37634 sum 134769, 134719 g++ 69349, 61058 61467, 63545 61614, 63752 56027, 60102 sum 248457, 248457 gfortran 18895, 17502 19329, 19051 13950, 17583 17442, 15482 sum 69616, 69618 objc 693, 783 760, 669 609, 649 716, 677 sum 2778, 2778 ibstdc++ 4495, 4635 4001, 3629 3958, 4580 4970, 4580 sum 17424, 17424 The LRA enabled built Linux kernel and whole user-land packages boot and function normally, too. Instead of looking into random test suite failures, I would first rather try to allocate some time to look into some build failures for more advanced real-world open source packages that I observered over the last years and already occured unrelated of the LRA enablement. > > On Mar 7, 2024, at 20:08, Richard Biener <rguent...@suse.de> wrote: > >> I saw the deprecation of ia64*-*-* scrolling by [1]. > >> > >> Which surprised me, as (minor bugs aside) gcc ia64*-*-linux just works for > >> us and > >> we still actively support it as part of our T2 System Development > >> Environment [2]. > >> > >> For ia64 we are currently a team of three and also keep maintaining > >> linux-kernel and > >> glibc git trees with ia64 restored and hope to bring back ia64 to linux > >> upstream the > >> coming months as promised.
