Hey, glad to hear of some improvement on GCC for the PDP-11. Last spring I ended up side-tracked on the QSIC project and working more on FPGA issues than writing PDP-11 code but that's going to change here at some point. I still want to put a soft PDP-11 into the FPGA as an I/O controller and will need to be writing code for it.
For the moment, I'm off at my summer job in Alaska but when I get home this fall, it's back to working away on the QSIC and maybe my PDP-10 project where I'm thinking I may also use a soft PDP-11 as an I/O processor. Anyway, I'll grab up the new GCC and see if my issues with the 'volatile' keyword are still there. Dave
