But for floats it doesn't, so applying that optimization there was wrong. Luckily it was caught by a nullptr dereference later in `emit::Xjcc()` for the (missing) unordered branch target, instead of miscompiling. fix some more cases of signed integer overflow 2026-03-08T18:03:59+00:00 lemon lsof@mailbox.org 2026-03-08T18:03:41+00:00 urn:sha1:d943de389796a44e40be39ef46aa5be01013a166 x86_64/emit: fix float store zero, unsafe range check for mul immediate 2026-03-08T18:03:59+00:00 lemon lsof@mailbox.org 2026-03-08T17:40:22+00:00 urn:sha1:77f78e58c94812d1ec40b57df86d2a87e6f32b41 x86_64/isel: cleanup and fix edge cases 2026-03-08T11:13:31+00:00 lemon lsof@mailbox.org 2026-03-08T11:12:41+00:00 urn:sha1:0a9b4736ca028e1637311a6cc0753bbb9351e951 add bswap16/32/64 2026-03-02T16:52:57+00:00 lemon lsof@mailbox.org 2026-03-02T16:52:57+00:00 urn:sha1:f2285400e65dafe730a073b3ca92494d72c7295b - frontend: __builtin_bswapX intrinsics - backend: ObswapX instructions ir: make address ref hash table resizable 2026-02-28T19:38:55+00:00 lemon lsof@mailbox.org 2026-02-28T19:38:55+00:00 urn:sha1:f06da11d8524a9eb7fe984171d4462cef8eac2e6 Would hit the limit on very large functions (thanks csmith). backend: fix edgecases where imm32 immediate overflows 2026-02-28T08:27:07+00:00 lemon lsof@mailbox.org 2026-02-28T08:15:15+00:00 urn:sha1:c739270317a409ac4c4782dabd5f9ff82d200045 fix various warnings 2026-02-24T14:47:10+00:00 lemon lsof@mailbox.org 2026-02-24T14:47:10+00:00 urn:sha1:9f202ac53acfac00addb5b6e4c9b1e5c7a33ea45
