Object allocations from the garbage collector are now inlined in ZJIT.

Virtual Machines are pervasive in the design and implementation of programming systems. In fact, languages implemented as virtual machines are crucial in the specification, implementation, and deploym...

After reading Chris Fallin’s aegraph post, new ZJIT contributor dak2 landed a block-local version of the canonicalize function in #16828.

NB: This isn’t about crypto. I don’t care about crypto.

As you may know, one area of Ruby performance optimization that particularly interests me is memory usage. Given that most Ruby deployments rely on fork, improving Copy-on-Write performance is general...

Research in the EGRAPHS Community has recently exploded in both quantity and diversity. The data structure that powers SMT solvers is now seeing use in synthesis, optimization, and verification via eq...

Short post today. New ZJIT contributor dak2 submitted a PR to fix an overflow bug in fixnum division in ZJIT. We did the division fine, but lied about the type of the result in the case of dividing FI...

Compilers, especially method just-in-time compilers, operate on one function at a time. It is a natural code unit size, especially for a dynamic language JIT: at a given point in time, what more infor...

We would like to make instance variable reads in the JIT compiler faster (as well as simplify the JIT implementation). Currently, in order to read an instance variable, we have to: Test for heap ...
