fix(codegen): share imported static update storage - #8666
Conversation
📝 WalkthroughWalkthroughThe compiler adds dedicated lowering for matching static class-field updates, including imported-class references. A regression test covers shared static storage, post-increment behavior, dynamic reads, ECS component data, multiple runtime modes, and forced GC evacuation. ChangesStatic field update correctness
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The codegen change is localized, but the regression test does not clear PERRY_GEN_GC_EVACUATE, so inherited environment settings could invalidate its forced-evacuation coverage; the PR is mergeable with explicit owner awareness or a follow-up to isolate that variable. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Add PERRY_GEN_GC_EVACUATE to GC_ENV_OVERRIDES.
The list clears 11 collector knobs but omits PERRY_GEN_GC_EVACUATE. An inherited value for that variable survives into both the normal and the forced-evacuation arm. That can make copying minor GC ineligible and silently invalidate the relocation coverage this test exists to provide.
🧹 Proposed fix
const GC_ENV_OVERRIDES: &[&str] = &[
"PERRY_GEN_GC",
+ "PERRY_GEN_GC_EVACUATE",
"PERRY_GC_SCAVENGE",Based on learnings: in Perry relocating-GC regression tests that spawn compiled binaries, explicitly remove inherited collector-knob env vars, including PERRY_GEN_GC_EVACUATE, because inherited settings can make copying minor GC ineligible and silently invalidate relocation-sensitive tests.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
