Logic for this was duplicated. Updated in c4d9087746 but only in one of
the places, so broke on some PIC code.

It was wrong for functions that didn't use the frame pointer but took
arguments in the stack
backend: inlining improvements2026-04-09T13:28:27+00:00lemonlsof@mailbox.org2026-04-09T13:28:27+00:00urn:sha1:c4d90877469e801c34066a7f823ffb1144dd5851Implement basic aarch64 struct arg passing ABI2026-04-08T08:26:18+00:00lemonlsof@mailbox.org2026-04-08T08:26:18+00:00urn:sha1:8b79b61ae78c91c069447331ed64d400187bdd77
- Missing: vaargs, >2 member HFAs
- Reworked the way stack allocation references are lowered. 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.
x86-64: redzone optimization for leaf functions2026-03-27T12:58:44+00:00lemonlsof@mailbox.org2026-03-27T12:58:44+00:00urn:sha1:b8dea129488959adeadc2e444d769f2a2ac709d8
Don't use frame pointer or explicitly modify stack pointer for these
IR: emit inline function standalone bodies lazily2026-03-23T22:43:52+00:00lemonlsof@mailbox.org2026-03-23T22:38:53+00:00urn: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.
style: change uvlong -> u64int, vlong -> s64int2026-03-22T21:00:35+00:00lemonlsof@mailbox.org2026-03-22T21:00:35+00:00urn: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.
regalloc & emit: explicit comparisons over memcmp of small structures2026-03-19T10:51:13+00:00lemonlsof@mailbox.org2026-03-19T10:51:13+00:00urn:sha1:46fc55e27390ea85eb34ec0367f40426197c9b9f
The one in x86-64_emit was not portable due to relying on zero
initialization of inactive union fields/padding.
Refactor: use typedefs and CamelCase for aggregate types2026-03-18T10:33:41+00:00lemonlsof@mailbox.org2026-03-18T10:33:41+00:00urn:sha1:1d9e19fb3bb941cdc28e9d4c3063d3e213fd8312
Looks nicer
