X Title: GH-135379: Support limited scalar replacement for replicated uops in the JIT code generator. by markshannon · Pull Request #135563 · python/cpython

Description: This PR does three things: Performs limited replacement of array stack items with scalars for uops. Modify replicate to support ranges starting from values other than zero Replicates COPY and SWAP to take advantage of that. With TOS caching this should allow COPY and SWAP to be implemented as register-to-register moves. Issue: gh-135379
