Rev	Log message	Author	Age	Path
12	Bunch of changes while trying to get a hello world program: 1. Right shifts by 32 or more now result in zero, or all of the top bit in the case of ASRs. 2. zdump now properly includes addresses with dumped lines. 3. zparser now properly handles immediate values via the .DAT instruction.	dgisselq	3407d 11h	/zipcpu/trunk/rtl/core/cpuops.v
3	Rebuilt the pipefetch (instruction fetch/cache module) so that it will let go of the bus if the memory unit wants it to execute an instruction. Pipefetch will then grab the bus back whtn the memory unit is done, so things otherwise continue as they were before. Other tweaks were made to try to reduce code complexity.	dgisselq	3408d 16h	/zipcpu/trunk/rtl/core/cpuops.v
2	An initial load. No promises of what works or not, but this is where the project is at.	dgisselq	3409d 09h	/zipcpu/trunk/rtl/core/cpuops.v
