feat(pkg): compat.gmp 三平台支持 —— 去掉 install()/autotools,改为纯描述符构建

README.md

@@ -52,8 +52,9 @@ Two kinds of packages live here:
 | Host runtime adaptation (drivers are not vendored) | [`compat.glx-runtime`](pkgs/c/compat.glx-runtime.lua) · [`compat.vulkan-runtime`](pkgs/c/compat.vulkan-runtime.lua) (mcpp binaries run against a bundled glibc, so a bare-soname `dlopen` never reaches the host drivers; a symlink farm plus `runtime.library_dirs` bridges that. Note the farm holds only versioned sonames — `library_dirs` also joins the link line) |
 | Always-on interface define | `CURL_STATICLIB` in [`compat.curl`](pkgs/c/compat.curl.lua): `cflags` is always on but package-private, while a feature's `defines` reaches consumers yet has to be named — `default = { implies = … }` applies unconditionally and happens to give both |
 | Multiple majors in one package (shape switches with the version) | [`compat.catch2`](pkgs/c/compat.catch2.lua) (3.x compiles `src/catch2/` into a static library; 2.x goes header-only through `single_include/`) |
-| External build system (`install()` builds from source) | [`compat.openblas`](pkgs/c/compat.openblas.lua) (Make) · [`compat.openssl`](pkgs/c/compat.openssl.lua) (Perl Configure + Make, static libssl/libcrypto) · [`compat.gmp`](pkgs/c/compat.gmp.lua) (GNU configure + Make, static libgmp — portable generic-C kernels, linux/macOS) |
+| External build system (`install()` builds from source) | [`compat.openblas`](pkgs/c/compat.openblas.lua) (Make) · [`compat.openssl`](pkgs/c/compat.openssl.lua) (Perl Configure + Make, static libssl/libcrypto) |
 | Whole-source direct build (config snapshot + source list, no external build system) | [`compat.ffmpeg`](pkgs/c/compat.ffmpeg.lua) (2281 TUs including NASM assembly, declared through 28 directory globs) |
+| Build-time generator output vendored into the descriptor | [`compat.gmp`](pkgs/c/compat.gmp.lua) (516 TUs, all three platforms. GMP's build COMPILES AND RUNS seven table generators and substitutes `gmp.h` from `gmp-h.in` — all of it a pure function of limb=64/nail=0, so the outputs are produced once by upstream's own generators and shipped in `generated_files` (~270 KB, of which `trialdivtab.h` is 109 KB). That is what removes the `install()` hook, autotools, and the host compiler its probes needed — and with them the reason windows was deferred, since GMP's generic C only ever needed a GCC-compatible compiler. `generated_files` also carries a one-line forwarding header per source directory, so the package compiles with **no `-I` at all** and `include_dirs` exposes `gmp.h` + `gmpxx.h` rather than GMP's private headers. Verified against a `--disable-assembly` autotools build of the same tarball: identical 598-symbol export set, and GMP's own `make check` passes 177/178 against it) |
 | Module layer over a compat source build (external Form-A repo) | [`godotengine.godot-cpp-m`](pkgs/g/godotengine.godot-cpp-m.lua) (two versions tracking upstream: `10.0.0-rc1` = Godot 4.6, `4.5.0` = Godot 4.5. `import godot_cpp;` re-exports the whole `godot` namespace, ~1800 names GENERATED from the headers rather than curated; the 1022-TU build stays in `compat.godot-cpp`, so the index carries only this descriptor. Macros — `GDCLASS`, `GDREGISTER_CLASS`, `memnew`, `ERR_*` — are the one thing a named module cannot export, so the package ships a side header to include next to the import. It also ships a generated `hashfuncs.hpp` shim — upstream's header minus `static` on two functions whose bodies declare an unnamed union — without which GCC refuses the module interface outright, a hard error no `-W` flag reaches) |
 | C++23 module wrapper | [`nlohmann.json`](pkgs/n/nlohmann.json.lua) · [`marzer.tomlplusplus`](pkgs/m/marzer.tomlplusplus.lua) · [`neargye.magic_enum`](pkgs/n/neargye.magic_enum.lua) · [`boost-ext.ut`](pkgs/b/boost-ext.ut.lua) (upstream's own `include/boost/ut.cppm` reproduced verbatim but for one `__argc`/`__argv` shim that Clang-on-MSVC needs; namespace `boost-ext` since it is NOT an official Boost library) |
