Yingwei Zheng	126016b662	[InstCombine] Simplify nonnull pointers (#128111 ) This patch is the follow-up of https://github.com/llvm/llvm-project/pull/127979. It introduces a helper `simplifyNonNullOperand` to avoid duplicate logic. It also addresses the one-use issue in `visitLoadInst`, as discussed in https://github.com/llvm/llvm-project/pull/127979#issuecomment-2671013972. The `nonnull` attribute is also supported.

Yingwei Zheng	1b78ff6972	[InstCombine] Simplify the pointer operand of store if writing to null is UB (#127979 ) Proof: https://alive2.llvm.org/ce/z/mzVj-u I will add some follow-up patches to avoid duplicate code, support more memory instructions, and bypass gep instructions.	2025-02-20 23:53:45 +08:00
