862920 - Support string operations in PJS execution

Status: RESOLVED DUPLICATE of bug 877893

(Core :: JavaScript Engine, defect)

Description

[Niko Matsakis [:nmatsakis]]

Currently we do not support string operations (like addition, subtraction, comparison, etc) in PJS code.  This is because the rope code is rife with allocation.  It will take some refactoring to make that code able to run both in normal execution and in parallel execution.

I'm interested in solving this bug. But I don't have enough knowledge about parallel javascript.
Would you teach me as mentor?

I have a few question. Would you tell me?
1. What is the problem about rope with allocation? It is that need JSContext, right ?
2. Which MIR node can be parallel? I think following MIR node can be parallel. Is there any other node?
- MStringSplit
- MNewStringObject

I think I propose this bug as GSoC project.
Do you think it is suitable size for GSoC project?
