* aarch64: fix stack frame layout, againlemon2026-04-122-35/+37
| | | | | Turns out hardware enforces SP 16-bit alignment in every SP relative load/store, but QEMU doesn't emulate this.
* test/csmith.sh: add --no-packed-structlemon2026-04-111-1/+1

* x86-64/emit: fix stack arg offset for edgecaseslemon2026-04-111-1/+2
| | | | | It was wrong for functions that didn't use the frame pointer but took arguments in the stack
* c: fix bitfields in unionslemon2026-04-101-4/+6
|
* x86-64/isel: always test for ZF after shiftlemon2026-04-091-3/+3
| | | | | The shift instructions do not update flags if the shift amount was zero, so can't realiably do this micro optimization
* backend: inlining improvementslemon2026-04-093-13/+29

* mkintcon: bugfix clamp i32 to i32 rangelemon2026-04-092-3/+5
|
* x86-64/isel: fix stack addr regression from 8b79b61ae7lemon2026-04-091-2/+4
| | | | Checks for RADDR should also look for RSTACK when fusing addresses
* x86-64/isel: use integer stores for storing float constantslemon2026-04-091-2/+16
| | | | | Because the integer mov can have immediate operands, avoids a round trip through an XMM register.
* aarch64 handle more cases of stack relative addressinglemon2026-04-092-3/+21

* Implement basic aarch64 struct arg passing ABIlemon2026-04-0810-139/+204
| | | | | | | | | | - 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 functionslemon2026-03-272-9/+12
| | | | Don't use frame pointer or explicitly modify stack pointer for these

| | | | Undefined behavior by the standard but a GNU extension.

|
* regalloc: remove dead code for liveness fixuplemon2026-03-241-100/+22
| | | | | | I tested it and it seems this wasn't doing anything. Maybe at some point in the past it was needed to fix up a worse implementation of mem2reg? So turn it into a check. Maybe it's wrong and it can be necessary.

|
* mem2reg rewritelemon2026-03-242-108/+74
| | | | | | | Do it in 2 passes: 1. gather variables, 2. step thru RPO transforming loads/stores to each variable. 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 lazilylemon2026-03-2310-41/+139
| | | | | | | 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 suchlemon2026-03-238-44/+54
| | | | | That way they are not copied when inlining. Also rename ninstr -> ninstrtab. opnarg -> opnoper

* c: remove inline 'backing' type tag for enumslemon2026-03-233-9/+4
| | | | | | | | | | It was meant as a micro-optimization but actually keeping it in sync was annoying. This for example was broken: ``` extern enum foo { ... } g_foo; enum foo g_foo; ```
* style: change uvlong -> u64int, vlong -> s64intlemon2026-03-2222-125/+125
| | | | | 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.
