Phase 0 batch 1. Six typed-struct allocations switch from
amalloc(arena, NNu64): *T over-sized byte counts to alloc(T{...})!
with partial struct literal initialization. MAP_ANON-zero from
rt_alloc covers any field the literal omits — same contract the
amalloc bump arena provided via its explicit zero loop, but
without the rule-13 size literal at the call site.
Converted:
- w6a/asm.ww addreloc, addrelocdata, addfixup (areloc, afixup)
- w6l/sym.ww intern (lsym)
- w6l/dyn.ww loadso (lso), lexport
lexport's `if (vernamecs == nil) { e.version.ptr = nil;
e.version.len = 0i32; }` branch dropped — MAP_ANON-zero provides
the empty-version slot for free; the inverted `if (vernamecs !=
nil)` only takes the dcstrtostr path.
w6l/sym.ww:20 comment updated from "amalloc-zeroing" to
"alloc-zeroing gives 0, not -1" so the documented mechanism
matches the call.
w6a/obj.ww's 2 remaining amalloc sites (bufinit + bufgrow) are
runtime-N *u8 byte buffers, deferred to #8 (runtime-N alloc API).
Verified via 991_w6a_ww + 992_w6l_ww + 995_self_rebuild +
996_dyn_ww byte-identity. make test 132/132.
