New issue 207 by [email protected]: Consider preallocating ecx for left shift http://code.google.com/p/v8/issues/detail?id=207 In the inlined code for the left shift Smi operation, we use the IA32 shift instruction encoding that uses ecx as a fixed register. The shift left code sequence uses four registers, but this may be reduced to three by preallocating ecx (before popping the arguments from the frame) to ensure that neither argument is in ecx. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
