Detailed Description

A collection of dirty hacks to get C++ compilation going.

Author:

Markus L. Noga <markus@noga.de>

This stub provides the necessary runtime environment for basic C++. The following features currently work:

• Classes
• Inheritance
• new and delete
• Virtual methods and destructors

Several features are still amiss:

• Throwing an exception will abort the current thread.
• RTTI is unimplemented.

Function Documentation

void __builtin_delete (  void *  ptr  )

builtin delete function frees the memory block Parameters: ptr  the block to free Definition at line 80 of file stub.c. References free().

void* __builtin_new (  unsigned int  size  )

builtin new function creates a memory block for an object. Parameters: size  size of memory to allocate Definition at line 88 of file stub.c. References malloc().

void* __get_eh_context (   )

Return current exception handler context. FIXME: null pointer returned Definition at line 62 of file stub.c.

void __pure_virtual (   )

Definition at line 94 of file stub.c.

int __rtti_si (   )

FIXME: rtti nop hack. Definition at line 66 of file stub.c.

int __rtti_user (   )

FIXME: rtti nop hack. Definition at line 70 of file stub.c.

void __sjthrow (   )

Throw an execption in a setjmp environment. FIXME: this just terminates the task. Definition at line 55 of file stub.c.

void exit (  int   )

Abort execution. Functional version, calls exit(1) Definition at line 43 of file stub.c.
