--- passes/atoms_source_map.lua — Per-.word source-line map emitter for tape atoms. --- --- Writer: this pass, given `atom.paths` (the per-atom mutable surface owned by `emission_model`). Readers: --- `passes/dwarf_injection.lua` (synthesizes DW_TAG_inlined_subroutine + per-word line program rows) and the gdb-runtime --- wrapper at `scripts/gdb/gdb_tape_atoms.gdb` (loads the source map via `source `). --- --- Inputs from `atom.paths`: the ordered `items` stream, dense `word_events`, `invocations` views. Outputs: one --- `WORD N LINE L TEXT T` line per emitted `.word`, plus the per-word provenance form that DWARF synthesis consumes. --- --- **Two output forms** (per the workspace's per-emission-form pattern from `guide_metaprogram_ssdl.md`): --- 1. **Sourcemap.txt form** — `/.atoms.sourcemap.txt`. Format-version-tagged for forward-compat. --- Lives in `/` (build/gen). Mirrors the convention used by `annotation.lua` --- (`/.errors.h`) and `static_analysis.lua` (`/.static_analysis.txt`). --- Compile artifacts (`*.macs.h`, `*.offsets.h`) stay in `/gen/`. --- 2. **gdb-runtime form** — `/gdb_tape_atoms_runtime.gdb`. A pure gdb command script — addresses come --- from `nm`, the 9 user commands are static `define ... end` blocks. Emitted when `ctx.flags.gdb_runtime` is true --- AND `ctx.flags.elf_path` points to an existing ELF. Useful for `gdb-multiarch --without-python` users --- (the common case on Windows MinGW builds) — `source ` loads it with no Python / Tcl / Guile required. --- --- **Output format** (sourcemap.txt form): --- ``` --- # FORMAT_VERSION 1 --- # auto-generated by ps1_meta.lua (passes/atoms_source_map.lua) — DO NOT EDIT --- ATOM "" --- WORD 0 LINE 49 TEXT load_half_u(R_T0, R_FaceCursor, 0 * S_(S2)), --- WORD 1 LINE 49 TEXT load_half_u(R_T0, R_FaceCursor, 0 * S_(S2)), --- ...
