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:
But the .sum files already combine all the results into one file.

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.
