Have a quick question regarding C++ runtime heap initialization and MQX 4.2 using armclang 6.9.
So __main in armclang runtime standard library is called to initialize the library which calls __rt_lib_init.
I have r0 and r2 in __user_setup_stackheap set to zero as the memory is managed by MQX.
The problem is the runtime library seems to be making calls to _init_alloc to initialize the heap in __rt_lib_init call which is faulting out.
If I just skip over _init_alloc call using the debugger everything works as expected. MQX/task runs, new C++ object creation/malloc all uses MQX malloc.
Is there any way to tell the compiler/linker to not call _init_alloc as part of __rt_lib_init?
I haven't found a way to wrap the call using armclang like we can with g++ as a hack.
Thanks in advance.
