Improve Proxy recrusion check in their internal methods. (#4568)
In some parts of Proxy internal methods the compiler can do a bit of
tail call optimalization which would be ok, but the current stack limit
check framework in Jerry uses the stack pointer to calculate the stack depth.
This way of stack depth calculation is affected by the tail call optimalization
(as the stack does not increase).

By disabling the tail call optimalization at given points the stack limit calculation
will work as expected. This causes a bit of stack overhead, but the Proxy in it self
is a fairly big chunk of code and this stack limit would only be relevant if the Proxy
already does recusion which already very edge case.

The stack limit (--stack-limit=..) should be enabled to correctly report such stack
depth errors.

JerryScript: JavaScript engine for the Internet of Things

License GitHub Actions Status AppVeyor Build Status FOSSA Status IRC Channel

JerryScript is a lightweight JavaScript engine for resource-constrained devices such as microcontrollers. It can run on devices with less than 64 KB of RAM and less than 200 KB of flash memory.

Key characteristics of JerryScript:

  • Full ECMAScript 5.1 standard compliance
  • 160K binary size when compiled for ARM Thumb-2
  • Heavily optimized for low memory consumption
  • Written in C99 for maximum portability
  • Snapshot support for precompiling JavaScript source code to byte code
  • Mature C API, easy to embed in applications

Additional information can be found on our project page and Wiki.

Memory usage and Binary footprint are measured at here with real target daily.
