It seems the __lshrdi3 symbol was dropped from libgcc.a from gcc-11 for

This is gcc bug. There's a typo in libgcc/config/pa/t-dimode:
# Extra DImode libgcc2 functions to build.
lib2difuncs = _muldi3 _negdi2 _lshrdi _ashldi3 _ashrdi3 _cmpdi2 _ucmpdi2
Will fix.
This is now fixed in upstream gcc source.
Thanks for fixing, Dave!
So, my patch:
https://patchwork.kernel.org/project/linux-parisc/patch/20211127105818.299902-1-deller@xxxxxx/
and Mikulas patch:
https://patchwork.kernel.org/project/linux-parisc/patch/alpine.LRH.2.02.2111270717490.10680@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/
won't be needed.
Yes. I will rebuild gcc-11 with fix but that will take a day or so. In the meantime, gcc-10 should work.
But it would be good to know if the shift routines in libgcc are needed with gcc-11. All the shifts should be inline.
