Introduce r2off, realize in x86-64 it's always 8; even `struct {i32 a; f32 b;}` gets passed in one (integer) register. But not so in (future) ABIs like RISC-V, I believe there `{i32, f32}` would get passed in 1 integer and 1 float register (r2off = 4). add command-line predefined macros (-D, -U) 2025-12-06T10:55:41+00:00 lemon lsof@mailbox.org 2025-12-06T10:41:44+00:00 urn:sha1:d82f3052c813f671561362126d0fbe08568542d3 amd64: va_arg for small aggregates 2025-11-23T16:10:30+00:00 lemon lsof@mailbox.org 2025-11-23T16:10:30+00:00 urn:sha1:bd3307a3e98e75b7cce5aa130719022a00323e0f implement float varargs, and some other fixes 2025-11-23T14:29:55+00:00 lemon lsof@mailbox.org 2025-11-23T11:02:27+00:00 urn:sha1:1f72464c6451fcff16180d00af537225acc9b83c sysv: nested scalar classification of struct shouldn't return KPTR, used to indicate aggregate in the stack 2025-11-22T12:25:07+00:00 lemon lsof@mailbox.org 2025-11-22T12:25:07+00:00 urn:sha1:6256bc1d0485a74e7d6728c95603a54a4149cb64 change op names to match 285063eba44 2025-11-21T15:49:53+00:00 lemon lsof@mailbox.org 2025-11-21T15:49:53+00:00 urn:sha1:ec4cfe9db9afc1d1c633a922174f5bb0685b0c32 rename IR classes to reflect bitsize 2025-11-21T10:03:23+00:00 lemon lsof@mailbox.org 2025-11-21T10:03:23+00:00 urn:sha1:285063eba442e2a8ac29fd42e0d17d996bcc5d00 sysv: document vaargs stack layout stuff 2025-11-14T18:23:18+00:00 lemon lsof@mailbox.org 2025-11-14T18:23:18+00:00 urn:sha1:57223ba45c4a88003826d25557a965d208c28639
