TraceMonkey Tasks

Here are a few pending tasks. Most of them benefit Tamarin-Tracing and TraceMonkey. Tasks that only benefit TraceMonkey are marked with a star(*).

• Setup performance & compliance test framework for shell using a MacMini.(*)
  • Skill set: perl, shell scripts and such
  • Effort: couple days tops

• Cleanup page allocation code in nanojit.
  • Skill set: C/C++, gdb, some understanding of Tamarin would be good
  • Effort: 1 week

• Make more JSOPs traceable.(*)
  • Skill set: solid experience with SpiderMonkey
  • Effort: on-going

• Implement soft-float math in TraceMonkey. The code already exists in Tamarin-Tracing and just needs to be ported over. Coordinate with upstream maintainer to extract soft-float code into a filter and get a patch for that into Tamarin-Tracing.
  • Skill set: C/C++, gdb, no fear of ARM assembly
  • Effort: 2 weeks

• Add loop-spanning register allocation to nanojit and get patch into Tamarin-Tracing.
  • Skill set: C/C++, gdb, experience with compiler construction advisable
  • Effort: 2-4 weeks, depending on implementation strategy

• Fix vprof in Tamarin to make it usable on Mac and Linux.
  • Skill set: C/C++
  • Effort: 2 days

• Help Intel with type stability analysis on real-world JS code.
  • Skill set: understanding of JS, C/C++
  • Effort: 2 weeks

• Port nanojit to PowerPC (lower priority).
  • Skill set: solid understanding of architecture issues, C/C++, lots of gdb
  • Effort: 4 weeks

• Update ARM/Linux JIT
  • Skill set: ARM assembly, C/C++, gdb
  • Effort: 2-4 weeks?
