Add gen-insn-tests.pl, a prototype tool that generates one travis test directory per non-pseudo instruction mnemonic (asm + json + golden output), by parsing x86/insns.xda (the already-generated, macro- expanded, one-template-per-line intermediate NASM produces from insns.dat) rather than insnsa.c/insnsb.c or hooking insns.pl. Rationale: insnsa.c/insnsb.c encode operands as opaque bitmask constants and index into an explicitly-unstable, shared bytecode array (x86/bytecode.txt: byte codes can be moved and recycled at any time), making them fragile/high-effort to parse from outside insns.pl. insns.xda already provides exactly the needed semantic info (mnemonic, comma-separated operand-type tokens, flags) in a small stable text grammar, with zero changes to insns.pl or the build. We only need valid operand *syntax* per operand-type token -- NASM picks the encoding itself from mnemonic + operand syntax -- so the generated tests are regression tests against a golden captured from a known-good nasm build, consistent with the rest of travis/. Includes UNDOC/OBSOLETE/NEVER-flagged instructions (only PSEUDO pseudo-ops are excluded): where these emit an expected warning (e.g. -w+obsolete-removed), the generator declares a stderr target so the warning text itself becomes part of the golden, verifying the warning fires rather than skipping the coverage. Delegates golden capture to tools/travis/nasm-t.py update instead of re-implementing it, so goldens get the harness's existing correctness properties (reproducible-build NASMENV, path-embedding conventions, etc.) for free. Generated travis/insns/<mnemonic>/ for all 2432 assemblable mnemonics (16/32/64-bit variants as applicable). Full suite validated via tools/travis/nasm-t.py: 4225 total, 4224 PASS, 1 pre-existing SKIP, 0 FAIL. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |
