More elegant solution to f9e3a52eaa. More efficient since all variable usages are visited in CFG order, which matters due to block sealing. IR: emit inline function standalone bodies lazily 2026-03-23T22:43:52+00:00 lemon lsof@mailbox.org 2026-03-23T22:38:53+00:00 urn:sha1:62d995124c0cc2eaeec79e18edc3e044f3e524c9 If a function is stashed for inlining and inlined in all of its callsites or unused, it never ends up in the object file. If any symbol reference to it is emitted, then it must be de-inlined (rematerialized), and this is done near the end before emitting the actual object file. IR: mark free'd instructions as such 2026-03-23T18:20:32+00:00 lemon lsof@mailbox.org 2026-03-23T18:20:32+00:00 urn:sha1:8630aeb8b43c507cd00f5b091ddcee4def464f4d That way they are not copied when inlining. Also rename ninstr -> ninstrtab. opnarg -> opnoper 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. I don't know whether I want to do it for the other int types too. char and uchar are fine as bytes. u/short -> u/s16int, maybe. IR: add 3rd operand to Instr 2026-03-22T09:49:26+00:00 lemon lsof@mailbox.org 2026-03-21T21:20:34+00:00 urn:sha1:79874c83bf76a5b3efd3d558933b90d9b53b829e The motivation is for aarch64 msub/madd instrs, for isel to produce. But it should be useful for other things too.
