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; static/BSS only for cross-call state. Prefer when writing or reviewing 8085 library asm,…
Game Boy CPU (LR35902 / gbz80) for z88dk: Zilog mnemonics, full opcode map (flags ZNHC, timings), GB-only ops (ldh, (hl+)/(hl-), ld hl,sp+*, add sp,*, swap, stop, reti), and z80asm synthetics. Use when writing or reviewing gbz80 library asm, +gb / -mgbz80…
80cc experimental/alternate C compiler in z88dk. Use when -compiler=80cc or working under src/80cc.
zsdcc (SDCC-based) compiler path in z88dk: -clib=sdcc_ix / sdcc_iy, newlib integration, and regenerating src/zsdcc/sdcc-z88dk.patch for SDCC upgrades (ABI 0, version string, ChangeLog revision, peep specials, c1-mode adb). Use when building with SDCC,…
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…
Vanilla upstream SDCC (not zsdcc) benchmark recipes: /usr/local/bin/sdcc, svn pin vs --version #NNNN, makebin -p, map-sum size, support/benchmarks/*/sdcc. Use when remesuring SDCC rows, tagging 4.6.0 #16608, or comparing stock SDCC to z88dk-zsdcc. Do not use…
sccz80 classic C compiler for z88dk: calling conventions, copt peephole path, 8080/8085/z80 runtime under libsrc/l/sccz80. Use when debugging sccz80 codegen or classic -compiler=sccz80 builds.
Intel 8080 coding for z88dk classic: no 8085 extended ops, no Z80 IX/IY/exx. Use when writing 8080 library runtime or +cpm -clib=8080 style products.
