The specific question is.

Is anyone producing "C" programs that result in 6309 instructions being 
actually used.

Yes I have the 6309 patch for RMA, two versions, the second one will be 

Yes there is an option in "cc" to call r63 instead of rma.


1) We have only a ipatch to covert rma to r63, if there are any problems it 
would take a enormous amount of work to correct them as source code is not 

2) Test cases, are any of the test cases from the ipatch author available, 
or any other test cases.

3) "cprep" has changed over the years, "cc" also "Ansifront has been 
inserted along with optimization programs. It has been many years, I cannot 
see a date in the ipatch file.

4) From the r63 readme:

Again, if you are producing "C" programs with 6309 instructions, please tell 

Otherwise a note will me made that this has NOT been tested.
