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. isel: fix flipped sub not being inplace 2025-12-05T18:10:56+00:00 lemon lsof@mailbox.org 2025-12-05T18:10:56+00:00 urn:sha1:aebb00df5fca3cbeb9edb415e584f36949ffb886 isel: fix immediate of flipped sub 2025-12-04T18:06:55+00:00 lemon lsof@mailbox.org 2025-12-04T18:06:55+00:00 urn:sha1:8a960c718d301b3a08e3513a88ebd617148311fb test/11-abi 2025-12-02T13:27:14+00:00 lemon lsof@mailbox.org 2025-12-02T13:27:14+00:00 urn:sha1:3c6e4dd54d5c144369b96d6673da7f23df4940da amd64/isel: fix addressing index shift being possibly too large to encode (duh) 2025-11-29T18:54:03+00:00 lemon lsof@mailbox.org 2025-11-29T18:37:43+00:00 urn:sha1:3cf75f807badf1d10e7bbeeeaaee13ed3eeb6bff isel: fix branch arg 2025-11-27T20:35:22+00:00 lemon lsof@mailbox.org 2025-11-27T20:35:22+00:00 urn:sha1:a86b5b99066c7369449c6d38dbccf1dbf6b65bca abi/isel: aggregate args in stack wip 2025-11-27T20:35:12+00:00 lemon lsof@mailbox.org 2025-11-27T20:35:12+00:00 urn:sha1:ba40fd10d0c6066c07cd651c25cefba8d75df9e0
