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 address registers, which can be anything between 32 and 64 bits (implementation defined, as far as I understand). > > On Sep 17, 2013, at 10:24 AM, Mike Stump <mikest...@comcast.net> wrote: > > On Sep 16, 2013, at 8:41 PM, DJ Delorie <d...@redhat.com> wrote: > >> m32c's PSImode is 24-bits, why does it have "32" in the macro? > >> > >> /* 24-bit pointers, in 32-bit units */ > >> -PARTIAL_INT_MODE (SI); > >> +PARTIAL_INT_MODE_NAME (SI, 32, PSI); > > > > Sorry, fingers copied the wrong number.
