 i've commited the main GCC 12.x sh fix to -current.
 
 while looking at the recent GCC changes in gcc/config/sh/ i noticed these
 three that look interesting:
 
    https://gcc.gnu.org/git/?p=3Dgcc.git;a=3Dcommit;h=3Df49267e163687212824=
 9431e9e5d20c0908b7e8e
 
 which seems to fix some optimisation pass issues, and could be merged into
 our GCC 12 i think.
 
    https://gcc.gnu.org/git/?p=3Dgcc.git;a=3Dcommit;h=3D58b78cf068b3b24c11d=
 7812a5f4de865e9cdb8b4
 
 which looks like the future has some code-size reduction coming, but
 maybe not until GCC 14 or 15...
