We use "MacroAssembler::" above. Would be good to be consistent everywhere. Ditto below. > Source/JavaScriptCore/dfg/DFGSpeculativeJIT.cpp:3528 > + jit.loadDouble(SpeculativeJIT::TrustedImmPtr(&zero), scratch); Why not use MacroAssembler:: qualifier instead?

We use "MacroAssembler::" above. Would be good to be consistent everywhere. Ditto below. Because SpeculativeJIT::TrustedImmPtr is different from MacroAssembler::TrustedImmPtr. It has some more extra checks. >> Source/JavaScriptCore/dfg/DFGSpeculativeJIT.cpp:3528 >> + jit.loadDouble(SpeculativeJIT::TrustedImmPtr(&zero), scratch); > > Why not use MacroAssembler:: qualifier instead? Ditto.
