Intel 8085 assembly for z88dk: Zilog mnemonics, full opcode map (flags K/V, timings), and extended-instruction usage. Strong rule: stack-only locals and intermediates; do not invent BSS scratch (C static / file-scope stay BSS). Prefer when writing or…
Intel 8080 assembly for z88dk: original ISA (April 1974), Zilog mnemonics, Pastraiser opcode/flag/timing map (S Z 0 A 0 P 1 C), stack-only locals, no 8085 extras, no Z80 IX/IY/exx. `jr` is a jp synthetic (normal mode). Use when writing or reviewing 8080…
KR580VM1 (КР580ВМ1) for z88dk: 8080-compatible plus RS/MB prefixes, H1L1, dual 64K banks, OF/MF flags, and ten extra ops. Use when writing or reviewing vm1 library asm, +test -clib=vm1 / +z80 -clib=vm1, -mvm1, pop-af bank traps, DSUB/LHLX/SHLX/DCMP, or…
Am9511A (Intel 8231A) APU float library: IEEE host format vs APU format, pushf/popf status mapping, IEEE-side specials, classic/newlib link flags, multi-product rebuild. Use when editing libsrc/math/float/am9511, APU I/O, or measuring --math-am9511 / --am9511.
math32 IEEE single float library: multi-CPU layout (asm/z80, asm/8085, asm/8080, asm/vm1, asm/gbz80), products math32*.lib including ez80_z80 / gbz80 / vm1, rounding policy, div=restoring / inv=NR, force rebuild. Use when editing libsrc/math/float/math32 or…
How to measure and prove z88dk library changes: z88dk-ticks TIMER/hotspots, map/nm proof, suite gates, A/B library swaps, math32 multi-CPU rebuilds, classic +test benchmarks, wiki number paste rules. Use when optimising, explaining deltas, or running +test…
zcc front end: +target compile/assemble/link, -clib, -compiler, -m map, --math32, -create-app. Use for any z88dk build line.
Z180 notes for z88dk: mlt multiply, math32_z180, eZ80 Z80-mode mlt share, ticks -mz180 / -mez80_z80, ASCI/IO context for yaz180/scz180 targets. Use when writing or measuring Z180 or eZ80-Z80-mode float/mul code.
