FYI,
The file funit-asm.h defines a number of simple instructions using
macros. This helps simplify the problem of writing generic assembler.
I've just committed a change to make it more generic with:
- making instruction arguments parameters to the macros
Different assemblers order source/dest differently.
- defining immed versions of load and compare.
Some assemblers use $ for immed, some do not.
- adding explict ENTER/EXIT macros
Different assemblers have different function entry (EPILOGUE) and EXIT
(EPILOGUE) conventions
Mark, in particular, this should make implementing assembly level step
tests much simpler and more portable.
