Hi,
this was found as part of Ubuntu's build of qemu for the upcoming 22.10
release.
That already uses gcc 12.2. But gladly it can be reproduced much easier as it
breaks in cross-building one of the firmware blobs.

Repro steps in Ubuntu 22.10:

Note: Sadly I have no more recent e.g. gcc-snapshot of the cross toolchain to
test.

The issue occurred on my laptop on the builders of Ubuntu, so I assume it is
pretty generic.

Details about how GCC was built can be fetched from the Ubuntu build logs at
https://launchpad.net/ubuntu/+source/gcc-12/12.2.0-2ubuntu1

I have tried to compare older builds using gcc on Jammy. The version
11.3.0-1ubuntu1~22.04 there works fine. So it seems to be a regression between
that and 12.2.0-2ubuntu1.

Note: I have found that setting -O1 (instead of the -O2 default) will mitigate
the issue.

Just drop -mbuild-constants.

(There is a problem in alpha_emit_set_long_const which is not prepared to
handle V4HImode target).

> Just drop -mbuild-constants.

Thanks for the hint Uroš, but I'm not sure if one can do that, this option is
from [1]. I do not have the background on this, but it reads as there was a
reason "Use -mbuild-constants to prevent the compiler using static data" to set
this which seems more breaking than my current workaround (reduce -O2 to -O1).

-mbuild-constants is used here together with -msmall-data (which limits
relocations to the small data area to 16 bits). -mbuild-constants option tries
harder to construct 64-bit constants using arithmetic with immediates instead
of loads from the small data area. So, if the linker does not error out with
relocation overflow, it can be safely omitted.

The fix to the compiler is relatively straightforward, but I have no access to
alpha system any more to properly test the fix (and I have no patience to run
the testsuite on the simulator). The -mbuild-constant option is rarely used,
and the proposed workaround should be safe.

Thanks Uroš for the explanation.

I've tried and it does not bail out with a relocation overflow when dropping
-mbuild-constants.

I've suggested to upstream to consider that change.

I can queue this up to test on real hardware.  By bootstrap, do you mean with
--enable-bootstrap, and by test do you mean a full testsuite run or just
checking that it doesn't ICE on the reproducer here?

I have already checked that it doesn't ICE with a crosscompiler. Regarding the
bootstrap, please note that --enable-bootstrap is the default nowadays, so the
option it is not needed to make a full build ("bootstrap"). Also, "make -j N -k
check-gcc" should be enough to test the compiler, since other parts of the
compiler never exercise -mbuild-constants (N in the command should be
substituted with a number of processors to parallelize the testsuite run).

I was just checking because alpha hardware is quite antique, it's single-core
so a full compile with bootstrap takes around ~72 hours.  I don't know how long
the test suite takes because I've never run it on this machine, but I would
expect it to add a couple additional days to that.  If that's fine I'll kick it
off, just want to be clear on what exactly you'd like to see.
