m32c has a 24 bit PSImode. It really does have 24 bit registers. Pointers are 32 bits when stored outside of registers, but the assembler and linker certainly support 24 bit constants, including a .3byte pseudo for setting up some of the chip-specific tables. Note also that gcc has mode_wider[] and mode_2xwider[] to differentiate between those.
