I implemented the microcode for the 16 bit, 8 bit low, and 8 bit high variants of AND, OR, and XOR this evening, which went smoothly (if a bit tediously). At this point 47 instructions are implemented in microcode, and […]
The new LLVM-based assembler is fully working, and 100% of the regression tests have been moved over to it as of this afternoon. It took close to 9 months to get done, but it’s all working now and gives us […]
I’ve spent the last few evenings tweaking the LLVM backend’s MC code to fix a lot of minor issues, and it’s to the point where it can generate normal output from ECLair assembly input now! It understands that different instructions […]
Worked on the LLVM backend a bunch more this evening, and it successfully assembled something for the first time! Halt is just 0xfe but the backend only understands 16-bit instructions at the moment, so it assembled as noop, halt, but […]
I haven’t made any posts here in ages, but that doesn’t mean that work hasn’t been happening behind the scenes! I looked at what my options were last fall when it came to assemblers, and it looked like I had […]
