1023106 - PJS: CallInitElementArray is used for some array literals, and causes bailouts for reasons of unsafety

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine, defect)

Description

[Lars T Hansen [:lth]]

Consider the two attached ray tracers.  They are identical, except that one uses objects {obj:..., dist:...} for multiple-value return and the other uses arrays [..., ...], both constructed by means of literals.

The array version never enters the parallel engine because it is constructed using the CallInitElementArray operation which is considered unsafe.

I believe some other programs that use array literals work fine in parallel, so this is likely some corner case.
