Move LinkBuffer/RepatchBuffer out of AbstractMacroAssembler.
( ​https://bugs.webkit.org/show_bug.cgi?id=27485 )

This change is the first step in a process to move code that should be in
the architecture-specific MacroAssembler classes up out of Assmbler and
AbstractMacroAssembler.

• JavaScriptCore.xcodeproj/project.pbxproj:
  • added new files

• assembler/ARMAssembler.h: (JSC::ARMAssembler::linkPointer):
  • rename patchPointer to bring it in line with the current link/repatch naming scheme

• assembler/ARMv7Assembler.h: (JSC::ARMv7Assembler::linkCall): (JSC::ARMv7Assembler::linkPointer): (JSC::ARMv7Assembler::relinkCall): (JSC::ARMv7Assembler::repatchInt32): (JSC::ARMv7Assembler::repatchPointer): (JSC::ARMv7Assembler::setInt32): (JSC::ARMv7Assembler::setPointer):
  • rename patchPointer to bring it in line with the current link/repatch naming scheme

• assembler/AbstractMacroAssembler.h: (JSC::AbstractMacroAssembler::linkJump): (JSC::AbstractMacroAssembler::linkCall): (JSC::AbstractMacroAssembler::linkPointer): (JSC::AbstractMacroAssembler::getLinkerAddress): (JSC::AbstractMacroAssembler::getLinkerCallReturnOffset): (JSC::AbstractMacroAssembler::repatchJump): (JSC::AbstractMacroAssembler::repatchCall): (JSC::AbstractMacroAssembler::repatchNearCall): (JSC::AbstractMacroAssembler::repatchInt32): (JSC::AbstractMacroAssembler::repatchPointer): (JSC::AbstractMacroAssembler::repatchLoadPtrToLEA):
  • remove the LinkBuffer/RepatchBuffer classes, but leave a set of (private, friended) methods to interface to the Assembler

• assembler/LinkBuffer.h: Added. (JSC::LinkBuffer::LinkBuffer): (JSC::LinkBuffer::~LinkBuffer): (JSC::LinkBuffer::link): (JSC::LinkBuffer::patch): (JSC::LinkBuffer::locationOf): (JSC::LinkBuffer::locationOfNearCall): (JSC::LinkBuffer::returnAddressOffset): (JSC::LinkBuffer::finalizeCode): (JSC::LinkBuffer::finalizeCodeAddendum): (JSC::LinkBuffer::code): (JSC::LinkBuffer::performFinalization):
  • new file containing the LinkBuffer class, previously a member of AbstractMacroAssembler

• assembler/RepatchBuffer.h: Added. (JSC::RepatchBuffer::RepatchBuffer): (JSC::RepatchBuffer::relink): (JSC::RepatchBuffer::repatch): (JSC::RepatchBuffer::repatchLoadPtrToLEA): (JSC::RepatchBuffer::relinkCallerToTrampoline): (JSC::RepatchBuffer::relinkCallerToFunction): (JSC::RepatchBuffer::relinkNearCallerToTrampoline):
  • new file containing the RepatchBuffer class, previously a member of AbstractMacroAssembler

• assembler/X86Assembler.h: (JSC::X86Assembler::linkJump): (JSC::X86Assembler::linkCall): (JSC::X86Assembler::linkPointerForCall): (JSC::X86Assembler::linkPointer): (JSC::X86Assembler::relinkJump): (JSC::X86Assembler::relinkCall): (JSC::X86Assembler::repatchInt32): (JSC::X86Assembler::repatchPointer): (JSC::X86Assembler::setPointer): (JSC::X86Assembler::setInt32): (JSC::X86Assembler::setRel32):
  • rename patchPointer to bring it in line with the current link/repatch naming scheme

• jit/JIT.cpp: (JSC::ctiPatchNearCallByReturnAddress): (JSC::ctiPatchCallByReturnAddress):
  • include new headers
  • remove MacroAssembler:: specification from RepatchBuffer usage

• jit/JITPropertyAccess.cpp:
• yarr/RegexJIT.cpp:
  • include new headers
