Maybe a dupe of PR108703? Need to rebuild with debugging symbols as well now.

With < 12, need -ftree-vectorize because the default changed. I can repro w/
10/11/12/13.
It's not very easy for me to bisect older versions because they don't e.g.
build with newer glibc and I always lose track of the patch(es) for those kind
of problems. But I'm pretty suspicious of this being a dupe still, so I guess
it's not so important.

Calling it a 12 regression because it now fails by default while the other PR
does not, but it's fine if you disagree.

The problem is that LRA assigns a floating-point register to the PIC
pseudo-register (pic_offset_table_rtx) and the SPARC back-end is not prepared
for it.
Vladimir, would it be feasible to prevent this from happening?

Sure. I'll work on this after my vacation (in one week).

Sorry, I can not reproduce it on gcc-11, gcc-12, and master using -O1
-mcpu=niagara4 -fpic -c a-sha512.i.
Fortunately, I can reproduce
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108703. So I'll start on PR108703
first.

You need a properly configured cross-compiler, which means that you need to
build and install binutils first. Then the most reduced testcase is the one
I'm going to attach:

This one is pathological though, so of a lower priority IMO.

By the way, I think this needs --enable-checking=rtl, which is maybe why you

No, that's incorrect. You need a properly configured compiler instead.

Okay. I couldn't hit it on some native machines until I rebuilt with more
checking, but maybe that was a fluke.

Sam, thank you for your help. I've reproduced the problem on your machine.
The fix most probably will be ready this week.

Thank you Vladimir! I appreciate the time both of you are spending on
alternative platforms for bugs like these.
Also, Vladimir, if you want to continue to use the machine after this, if you
ever have an occasion to do something on sparc, please feel free. Your account
will remain. The machine is made available for sourceware CI and for developers
to test for general stuff like this. Just email me if any questions or if you
want something installed, etc.

RA: Constrain class of pic offset table pseudo to general regs
On some targets an integer pseudo can be assigned to a FP reg. For
pic offset table pseudo it means we will reload the pseudo in this
case and, as a consequence, memory containing the pseudo might be
recognized as wrong one. The patch fix this problem.

* ira-costs.cc: (find_costs_and_classes): Constrain classes of pic
offset table pseudo to a general reg subset.
