Description Yuqiang Xian 2011-10-09 04:21:58 PDT
In JSVALUE32_64 DFG, DataFormatJSDouble is assumed to be represented by a FPR and will be used for further optimizations, though we currently don't fully utilize it. For now when filling a JS value which was spilled as a JSDouble with a pair of GPRs, we'll set the registerFormat to DataFormatJS to avoid compilation errors.
