Re: [v8-users] Running V8 on ARM64 Windows?
Hi, The arm64 port follows the procedure call standard defined here: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0055b/IHI0055B_aapcs64.pdf , I do not know if/how Windows on Arm differs. The main interface points are JSEntryStub, CEntryStub,and DirectCEntryStub (src/arm64/code-stub-arm64.cc). There are some other JS to C++ calls in TurboFan, look for the macro assembler function "CallCFunction" (used for calling Cos, Sin for example).

Grep src/x64/code-stubs-x64.cc for '_WIN64' and you'll find it used in methods like `CallApiCallbackStub::Generate()` and `CallApiGetterStub::Generate()`. The same methods in src/arm64/code-stubs-arm64.cc are likely the ones you want - and if not, grep for 'CallApiFunctionAndReturn'. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.

Re: [v8-users] Running V8 on ARM64 Windows?
Thanks Ben. Yes, I am experimenting port V8 to this platform. Would you please point me to the code which handles native code calling convention from JIT code? BTW: I am Microsoft employee working on this new Windows platform.

Are you planning to port it to that platform? V8 uses an internal calling convention in JIT-generated code. The only places where you need to worry about the native calling convention is at the edges, where generated code calls into native C++ code. Let me know if you need more details. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
