Description Dominik Inführ 2019-01-09 01:36:26 PST
DFG only supports general-purpose callee-saved registers but not floating-point registers in DFGOSRExit.cpp on 32-bit architectures. Extend functions `restoreCalleeSavesFromVMEntryFrameCalleeSavesBuffer` and `copyCalleeSavesToVMEntryFrameCalleeSavesBuffer` to support floating-point registers as well.
