Summary: Remove unused callOperation code of DFG JIT on X86
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: JavaScriptCore
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: yuqiang.xian at intel.com
CC: barraclough at apple.com, fpizlo at apple.com
We'll never reach callOperation(*EJJJ*) on X86 because it requires 6 GPRs while currently DFG JIT on X86 only provides 5 GPRs. For those operations which require 3 or more JSValue arguments (like instanceof) we spill the registers and load the data into registers on demand, push the parameters and directly invoke appendCall. Removing the unused callOperation code avoids some confusions.
