ffi 1.17: #jni_call(name, sig) literal-keyed slot interning
...
Two `#jni_call` sites with the same string-literal `(name, sig)` pair
now share a single `jclass` GlobalRef slot and a single `jmethodID`
slot, populated lazily on the first call to any matching site.
Non-literal sites keep the per-call `GetObjectClass` + `GetMethodID`
sequence from step 1.15.
Per-call-site lowering for literal sites:
%cached_mid = load ptr, @SX_JNI_MID_<key>
%is_cached = icmp ne ptr %cached_mid, null
br i1 %is_cached, cont, miss
miss:
%local_cls = GetObjectClass(env, target)
%global_cls = NewGlobalRef(env, local_cls) ; vtable slot 21
store ptr %global_cls, @SX_JNI_CLS_<key>
%fresh_mid = GetMethodID(env, global_cls, name, sig)
store ptr %fresh_mid, @SX_JNI_MID_<key>
br cont
cont:
%mid = phi ptr [%cached_mid, before], [%fresh_mid, miss]
call <Type>Method(env, target, %mid, args...)
Wiring:
- `JniMsgSend.cache_key: ?CacheKey` (new) carries `(name_str,
sig_str)` when both `name` and `sig` are string-literal AST nodes;
empty for non-literal call sites.
- `lower.zig` populates `cache_key` from the AST.
- `emit_llvm.zig` `getOrCreateJniSlots(name, sig)` returns the
`{cls_slot, mid_slot}` pair, creating and caching them on first
lookup. Key is `name\x00sig` so the separator can't collide with
any JNI identifier byte.
- `mangleJniKey` builds an LLVM-identifier suffix from the pair, used
in the `@SX_JNI_{CLS,MID}_<suffix>` global names.
IR snapshot at `tests/expected/ffi-jni-call-03-methodid-sharing.ir`
updated: two call sites against literal `("noop", "()V")` now share
`@SX_JNI_CLS_noop____V` and `@SX_JNI_MID_noop____V`. Pre-1.17 snapshot
had two independent `GetMethodID` calls; post-1.17 has one global
slot pair plus per-call lazy-init branches.
Note: an unrelated regression in `examples/ffi-objc-call-12-rect-u64-returns.sx`
exists in the working tree (parse error from an in-progress C-import
block) and is left untouched.
