ffi M5.A.next.2a.C: pack if-return — lock in slot-load uninit regression
...
Follow-up to issue-0045's fix (commit 9e78790 ). The fix routes
inline-comptime-body `return X;` into a result slot but sets
`block_terminated = true` after the inline return — and that
flag leaks past the enclosing `if`'s merge block.
Body shape:
maybe :: (..$args) -> s64 {
if args.len > 0 { return 42; }
return -1;
}
For `maybe()` (zero call-args), the false-condition path skips
the then-branch's `return 42;` and should fall through to
`return -1;`. Today's flow:
- Then-branch's `return 42;` stores 42 to slot and sets
block_terminated = true.
- if lowering switches to merge_bb. block_terminated stays
true (never reset across the if/merge boundary).
- lowerBlockValue's loop sees block_terminated and returns
null without processing the trailing `return -1;`.
- lowerComptimeCall loads slot — slot was never written on
the false-condition path → garbage (8354116000 on this
machine; stable across runs).
`maybe(99)` works because the cond is true; the then-branch's
store wins.
Next commit reshapes the inline-return mechanism to use a
dedicated "return-done" basic block: each inline `return X;`
stores to slot and branches to ret_done; after the body
lowers, lowerComptimeCall switches to ret_done and loads. The
basic block CFG carries the control-flow termination — no
need for the leaking `block_terminated` flag.
196/196 example tests + `zig build test` green (the new test
captures the wrong value as the snapshot to flip).
