[llvm] [KnownFPClass] Refine powi KnownFPClass deductions (PR #218581)
via llvm-commits
llvm-commits at lists.llvm.org
Mon Aug 24 21:03:43 PDT 2026
https://github.com/ZERICO2005 created https://github.com/llvm/llvm-project/pull/218581
Adds deductions for when the `base` is known never negative-normal nor negative-subnormal. Similar to the deductions added for `pow` https://github.com/llvm/llvm-project/pull/215592.
