Move ENCODE_RECIPES from a startup-built (@init) static table in the library to
a generated, #loaded table like every other one. The tablegen runs
form_to_recipe over every form, serializes to x86.encode_recipes.bin, and the
loader #loads it -- no @init, no allocation; the forms remain the single source
of truth and the recipe is derived from them.
- tablegen/gen.odin: ENCODE_RECIPES added to the BLOBS manifest (which drives
both the Stage B serializer and the loader's #load); emit the generated-package
global plus an @init that fills it from ENCODE_FORMS via lib.form_to_recipe.
- encoder_recipe.odin: drop the @init, the static storage, and the ENCODE_RECIPES
declaration. form_to_recipe stays -- now solely the tablegen-time derivation.
- tables.odin, generated/{encode_tables,writer}.odin: regenerated.
- tables/x86.encode_recipes.bin: the generated blob (28260 bytes = 2355 x 12).
No behavior change: the recipes are identical to the @init ones. gen / builders /
check / test / idempotent green (2282 cases, 22 byte-stable artifacts); encode
perf unchanged.
Move all ten ISA packages (x86, arm32, arm64, mips, riscv, ppc, ppc_vle,
rsp, mos6502, mos65816) from core/rexcode/<arch> to core/rexcode/isa/<arch>,
so the import pattern is now `import "core:rexcode/isa/x86"`. The shared
core stays at core:rexcode/isa.
Mechanical: relative `import "../isa"` / "../../isa" -> absolute
"core:rexcode/isa" (the only path that survives the move; the "../" and
"../.." self/generated imports move with their packages). build.lua now
builds paths as <root>/isa/<name>; stale `cd <arch>` hints in the verify
tools and the doc.odin paths updated.
WASM stays at core/rexcode/wasm for now -- it is an IR, not an ISA, and
will move under the forthcoming core:rexcode/ir once that layer lands.
All 10 arches gen/builders/check/test green; import core:rexcode/isa/x86
verified working; wasm still compiles.
