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. eval: fix errata in EGETF addr case 2026-03-22T16:22:15+00:00 lemon lsof@mailbox.org 2026-03-22T16:22:15+00:00 urn:sha1:2d0b096a8c2f45370ef2535e1c500a008b949611 The symref given by staticaddrof is in ex2, not sub. This worked by chance (with sub->ssym.off happening to be zero) on linux, but on OpenBSD it would give garbage. Which would result in messed up relocations later leading to miscompilations. 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. c: better preserve source location in some cases 2026-03-20T07:32:12+00:00 lemon lsof@mailbox.org 2026-03-20T07:32:09+00:00 urn:sha1:31032275a618f74865bdc877b569eae2227e79b4 c: fix edge cases with zero sized bitfields and static initializers 2026-03-18T22:10:25+00:00 lemon lsof@mailbox.org 2026-03-18T22:10:25+00:00 urn:sha1:1b782f049fa96d7ebccf93ad2b05fc30b938c870 Refactor: use typedefs and CamelCase for aggregate types 2026-03-18T10:33:41+00:00 lemon lsof@mailbox.org 2026-03-18T10:33:41+00:00 urn:sha1:1d9e19fb3bb941cdc28e9d4c3063d3e213fd8312 Looks nicer
