Sure, easy to do.
* machmode.def (PARTIAL_INT_MODE): Add precision and name.
* genmodes.c (PARTIAL_INT_MODE): Add pre

Can you please get rid of PARTIAL_INT_MODE_NAME by
making the name a required argument to PARTIAL_INT_MODE?
Ok with that change (given target maintainers are ok with this).
Thanks,
Richard.

So Richard said he'd review/approve it… He's been busy clearing out a backlog
or email/patches and reviewing wide-int stuff… when next he comes up for air,
I suspect
Who needs to approve this? THe target maintainers, or some global maintainer?
Ping?

Easy, perform it in the maximal size support

PSI is used for representing FPSCR (floating point control register),
which has only max. 22 bits (as far as I know).
PDI is used on SH-5 for representing target a
Can the sh people weigh in on this? Are the PSI and PDI precisions 32 and 64?

Sorry, fingers copied the wrong number. Thanks for the catch.

m32c's PSImode is 24-bits, why does it have "32" in the macro?

I like creating the name via algorithm. It leads to predictable names, and
easy to understand names. P60DI is obvious to a

True, but, all ports are trivial to fix so that the precision is included and
