Now RSTACK persists throughout all passes until emit. This allows deferring stack frame layouting until the end in a less messy way than before, which was emiting frame-pointer relative addresses @ isel time and patching them up later in emit to account for actual stack frame layout. aarch64 struct arg passing ABI wip 2026-03-25T15:36:29+00:00 lemon lsof@mailbox.org 2026-03-25T15:36:29+00:00 urn:sha1:79d6ac719042371d255ed1cf412e3232d13d1e56 style: change uvlong -> u64int, vlong -> s64int 2026-03-22T21:00:35+00:00 lemon lsof@mailbox.org 2026-03-22T21:00:35+00:00 urn:sha1:7c5dd45eca377a3b675b6f0d4a9331bc3f971ac9 Is much nicer.
