stefan brunthaler added the comment: While looking at the instruction frequency traces, I noticed that INPLACE_* instructions were not quickened to optimized instruction derivatives. The submitted patch fixes this issue and correctly generates code performing the substitution. The performance

stefan brunthaler added the comment: So I took a close look to what the performance problem was. Many of the benchmarks used by the perf.py py3k benchmarks use function calls for which there are no optimized derivatives available. In this case the function trying to do the quickening (aptly c

[issue14757] INCA: Inline Caching meets Quickening in Python 3.3

New submission from stefan brunthaler : The attached patch adds quickening based inline caching (INCA) to the CPython 3.3 interpreter. It uses a code generator to generate instruction derivatives using the mako template engine, and a set of utility functions to enable automatic and safe quicke
