[RISCV64] Define HAVE_MACHINE_CONTEXT, provide mcontext_t accessors for CPU(RISCV64)
https://bugs.webkit.org/show_bug.cgi?id=234718
Patch by Zan Dobersek <[email protected]> on 2021-12-28
Reviewed by Yusuke Suzuki.
Source/_javascript_Core:
Define HAVE_MACHINE_CONTEXT for RISCV64. In the MachineContext.h
header, CPU(RISCV64)-specific accessors into the mcontext_t struct
are also provided.
* runtime/MachineContext.h:
(JSC::MachineContext::stackPointerImpl):
(JSC::MachineContext::framePointerImpl):
(JSC::MachineContext::instructionPointerImpl):
(JSC::MachineContext::argumentPointer<1>):
(JSC::MachineContext::llintInstructionPointer):
Source/WTF:
* wtf/PlatformHave.h: Define HAVE_MACHINE_CONTEXT for CPU(RISCV64).
