#AMD はなぜ #AMD64 を #RISC モドキにしなかったのか?

Good morning! It's been a few days of work, but happily I think these are very promising results. My assembler is now able to assemble a good part of IA-64 / AMD64 / x86_64 code and run simple programmes calling the Linux kernel directly, no C library involved, which accounts for the performance difference in the first rough benchmark (unsophisticated but directionally right).

This assembler architecture is an extension improving on the zenas Z80 assembler, so it's likely that a future version will fold zenas into the new architecture, and the new unified assembler will target both architectures (initially Z80 and AMD64).

The parts it still can't assemble: legacy i386 modes, fpu x87, SSE, SIMD instructions. It's possible that I may never go through the hassle of implementing i386. The payoff of implementing ARM64 next is much more important I think (that opens a few other modern platforms, including the M1 and Raspberry Pi).

In the coming months, ironing out the assembler wrinkles, completing ELF64, Mach-O, and PE32 output, it starts to look like I might be able to make ual generate native binaries directly, adding a new ual-zenas backend. Probably Linux-only sometime by the end of the year, and the rest sometime in 2027.

My assembler is getting x64 and ARM64 smarts. This is the first time it assembles simple arithmetic, writes an ELF64 binary, and then signs off correctly with the right exit code on linux/amd64.

My journey to a #RealTimeLinux kernel for #AMD64 on Buildroot continues!

Many failed experiments with different kernel/RT patch combos (6.18, 6.12, 6.1), but learning a ton about patching & Buildroot quirks. Still stuck on enabling CONFIG_PREEMPT_RT, but feeling closer to the breakthrough!

My portable #BashLab is ready for more. 🤓
