| * | amd64: fix wrong condition code being used for float gth | 2025-12-07 | 1 | -1/+1 | |
| | | | | | ughh | ||||
| * | amd64: use XORPS for floating point negation | 2025-12-07 | 2 | -3/+7 | |
| | | | | | | | | | | | Previously `neg x` was being turned into `sub 0, x`. But this gives the wrong result for zero/negative zero (-0.0 == -0.0 but 0.0 - 0.0 == 0.0), so it wasn't IEEE compliant or correct. Do what every other compiler does instead and flip the sign bit with an exclusive or. Should implement someway of deduplicating small data constants like the ones used here though. | ||||
| * | abi: fix aggregate passed by regs 2nd reg offset | 2025-12-06 | 1 | -3/+7 | |
| | | | | | | | | | | It was broken for example `struct { i32 a; f64 b; }` (would try to load/store b from byte offset 4, not 8). 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). | ||||

| * | amd64: fix pseudo-push/pop float reg | 2025-12-05 | 1 | -2/+2 | |
| | | | | | | | With add/sub flags can be trashed which can result in miscompilations, use lea. This shouldn't even exist, need to get rid of xsave/xrestore, but for now fix this kludge | ||||
