820105 - IonMonkey: callWithABI: support passing the callee in a register

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Jan de Mooij [:jandem]]

We want to use callWithABI to make calls to native functions. However, the baseline compiler will share these "native call" stubs so we can't bake in the actual function pointer.

[Nicolas B. Pierron [:nbp]]

Just to clarify, you want to make a stub to call  bool (*)(JSContext *, int argc, Value *argv) cases ?  At best you should use a volatile register which is not in the set of argument to hold the pointer of the callee.

Attachment: Patch

This adds a callWithABI overload that takes the callee as Address instead of a function pointer.
