Hojun-Cho	d66aef382a	w6c+selfhost: cgen T-rooted chained N_DOT (closes #22 ) Spine walker now accepts T root at the last hop (cur->lhs->kind == N_IDENT, pu->kind == TY_PTR), substitutes pointee struct, emits MOVQ off(BP), CX before offset arithmetic. Symmetric in N_DOT and N_ASSIGN. Distinct gate from existing mid-chain T-field branch (cgen.c:4615) — no shadow. Unblocks task #18 (bufio writer first-field embed). Pre-existing T-field mid-chain path unchanged.	2026-05-14 02:44:57 +09:00

w6c+selfhost: cgen *T-rooted chained N_DOT (closes #22 )

Spine walker now accepts *T root at the last hop (cur->lhs->kind ==
N_IDENT, pu->kind == TY_PTR), substitutes pointee struct, emits
MOVQ off(BP), CX before offset arithmetic. Symmetric in N_DOT and
N_ASSIGN. Distinct gate from existing mid-chain *T-field branch
(cgen.c:4615) — no shadow.

Unblocks task #18 (bufio writer first-field embed). Pre-existing
*T-field mid-chain path unchanged.

w6c+selfhost: cgen chained N_DOT/N_ASSIGN spine walk

Loop-shaped spine walker for value-struct chains (o.i.a) and slice/str
pseudo-fields (s.buf.len), read+write, both stages. SB-fallback at the
catch-all preserved for unresolved module-qualified idents.

Follow-ups filed: tasks #7-#10 (wwstage >6-arg frame over-alloc, chained
array-elem field BX loss, & through chained DOT, signed sub-word field
loads zero-extend).
