Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 14f485ee by ARATA Mizuki at 2026-02-17T09:09:24+09:00 Support more x86 extensions: AVX-512 {BW,DQ,VL} and GFNI Also, mark AVX-512 ER and PF as deprecated. AVX-512 instructions can be used for certain 64-bit integer vector operations. GFNI can be used to implement bitReverse (currently not used by NCG, but LLVM may use it). Closes #26406 Addresses #26509 - - - - - a40e0e03 by fendor at 2026-02-17T04:25:04-05:00 Hide implementation details from base exception stack traces Ensure we hide the implementation details of the exception throwing mechanisms: * `undefined` * `throwSTM` * `throw` * `throwIO` * `error` The `HasCallStackBacktrace` should always have a length of exactly 1, not showing internal implementation details in the stack trace, as these are vastly distracting to end users.
