## Description Applies LLVM patches that have not been backported to the major version used in our submodule: * [LLVM PR #163679](https://github.com/llvm/llvm-project/pull/163679) * *"[RISCV] Allow large div peephole optimization for minsize"* * Fixes peephole optimization of large integers when `minsize` function attribute is set. * (Our revive codebase used a workaround that can be removed once this 500 PR is merged and we publish a new LLVM release.) * [LLVM PR #190219](https://github.com/llvm/llvm-project/pull/190219) * *"[TargetLowering] Speculative fix for a non-determinism issue between different compilers"* * Operand ordering of `mul i256` were different depending on the target ABI when building LLVM, producing different RISC-V and PVM bytecode for our Windows vs macOS/linux builds. * The bytecode divergence (yet functionally equivalent) affected Solidity contracts containing a value [multiplied by itself](https://github.com/llvm/llvm-project/issues/190148) (e.g. via explicit squaring or exponentiation), manifesting primarily when using optimization level `-O0`.
