​https://bugs.webkit.org/show_bug.cgi?id=169436

Reviewed by Mark Lam.

Source/JavaScriptCore:

This patch port VMTrap to Linux ports.
We extract MachineContext accessors from various places (wasm/, heap/ and tools/)
and use them in all the JSC code.

  • JavaScriptCore.xcodeproj/project.pbxproj:
  • heap/MachineStackMarker.cpp:

(JSC::MachineThreads::Thread::Registers::stackPointer):
(JSC::MachineThreads::Thread::Registers::framePointer):
(JSC::MachineThreads::Thread::Registers::instructionPointer):
(JSC::MachineThreads::Thread::Registers::llintPC):

  • heap/MachineStackMarker.h:
  • runtime/MachineContext.h: Added.

(JSC::MachineContext::stackPointer):
(JSC::MachineContext::framePointer):
(JSC::MachineContext::instructionPointer):
(JSC::MachineContext::argumentPointer<1>):
(JSC::MachineContext::argumentPointer):
(JSC::MachineContext::llintInstructionPointer):

  • runtime/PlatformThread.h:

(JSC::platformThreadSignal):

  • runtime/VMTraps.cpp:

(JSC::SignalContext::SignalContext):
(JSC::SignalContext::adjustPCToPointToTrappingInstruction):

  • tools/CodeProfiling.cpp:
