Future::AsyncAwait Final Report Here is the final report by Paul Evans on his Future::AsyncAwait Grant: This project set out to improve the Future::AsyncAwait module, fixing a number of known bugs and adding missing features. It also aimed to improve documentation and user-awareness of the new abilities that the module adds to Perl. I believe it has been successful in all of these areas. Bugs Fixed Of particular note, the original

While a number of intended deliverables for remain unmet, he's made significant contributions to the expression backend and has identified unexpected roadblocks to the remaining tasks that should yield to additional preparatory work. In light of this, the Grants Committee will be considering Bart's report below and voting on a payment for the currently accomplished work of 50% of the original amount requested. The Grants Committee will consider a revised

Update for Revitalize blogs.perl.org We've had several changes in the GC staffing since this grant began; I'm taking over as the Grant Manager. André's last published status is here: http://blogs.perl.org/users/andrewalker/2018/10/progress-of-blogsperlorg-grant.html Since then, he has received a DB dump so he can process actual data rather than "Lorem Ipsum" sample posts. This will allow him to run through the final iteration of work to attempt to process the exported posts and

Bart gave me this interim report on his grant: is essentially complete. Bart is currently finishing floating point support in conditional expressions. This is surprisingly nontrivial, he indicates, because of NaN, and because of condition code differences between floating point and integer comparisons. is nearing completion. Bart says it turned out to have a whole lot of overlap with the floating point support. He

Bart reports the latest progress: Fixed a few windows-specific bugs Assigned a permissible-register set to live ranges, which makes it possible to combine values with distinct register requirements Ensured that when a value is spilled to make place for another, the released register is actually one that the new value can use. In other words, a bunch of register allocator work. Floating point support is close to being finished. He

Timo developed a language named confprog, using which one can set entry points in the profiler. This is useful for selective profiling of large codebases. Read more at: "A Close Look At Controlling The MoarVM Profiler":https://wakelift.de/2019/05/22/close-look-at-controlling-moarvm-profiler/

Bart received helpful comments on his blog posts last month that will move him ahead with intermediate representation optimization and register allocation. He writes: I'm still working on finalizing the floating point support for the JIT compiler, but I've also started work on the new register allocation algorithm. This wasn't strictly a deliverable, but I expect it will help the deliverable of improving code generation. MAJ

Brrt reports that February was busy and short, but that he did some research on other implementations of register allocation that he can apply to MoarVM JIT. He notes the following conundrum that he has been thinking about. Maybe a reader can advise: I've also encountered a limitation in the optimization of the IR, which I'm trying to resolve. The issue is this, if I have a bunch of code

Brrt has hit the ground running on his MoarVM JIT Compiler grant. Here is his interim report: I wanted to start with floating point support, which has two subtasks: Ensure that DynASM encodes SSE instructions with variadic registers correctly. Ensure that the JIT itself accepts and works with floating point registers. I finished the first two of those tasks. For some context, x86-64 instruction encoding rules require an extra byte
