* parallel move; implement reg<->stack swp lemon2025-12-101-2/+3
|
* misc fixes lemon2025-12-101-3/+2
|
* amd64: fix wrong condition code being used for float gth lemon2025-12-071-1/+1
| | | | ughh
* amd64: use XORPS for floating point negation lemon2025-12-071-0/+1
| | | | | | | | | | 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.
* amd64: fix pseudo-push/pop float reg lemon2025-12-051-2/+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
