I would argue how such a bounty would be rewarded here because overall performance gains have been done by multiple submitters. For example, I've submitted a number of improvements to the optimiser to produce both smaller and faster machine code. And unfortunately not many of us have access

Re: [fpc-devel] The 15k bounty: Optimizing executable speed for Linux x86 / LLVM

Hello Simon - wondering if you have code examples that provoke problems you are experiencing? It will be easier to measure/test improvements with test cases. Solutions might not come from a single person/team and therefore not sure how to apply the bounty in the most effective/fair way. ___

[fpc-devel] Another blocking bug

Hi everyone, Sorry to be a pain, but it looks like there's another bug in FPC that blocks compilation on a particular platform: https://bugs.freepascal.org/view.php?id=34458 It seems a recent change to the PasToJS packages causes it to fail compilation on x86_64-win64.  SVN says the user "ma
