I do development for the Innovasic FIDO processor, which is an 68 K
CPU32 architecture, in fact a kind of upgrade tho the ubiquitously
used 68332 chip.
The Eclipse based IDE called Sourcery comes with a GNU compiler that
is built to work in FIDO-mode by default, but it also can be set to
compile for other chips (e.g. 68332, here it does not support the two
assembler instructions that are new with FIDO (e.g. sleep).
Do you know what version of gcc it uses?
Now I found that the code Generator seems to be rather bad. It generates
rather nasty code using a much higher count of instructions than
necessary, avoiding the more CISK-specific instruction in the CPU32
instruction set (such as moving a value from memory to memory, setting a
bit in a memory-cell, ...)
My very old MRI compiler for the 332 is a lot better on that behalf.
Is there any chance to find a more decent 68 K GNU C compiler ?
Have you considered compiling your own?
Regards
Greg
