RE: Re: static initializer

For all,

This was posted on our forums for the answer.


You control the location of _ctors and _dtors in the linker command
file. For example, assume that a valid address would be 0x00400000, you
would do something like 

MEMORY { 
... 
start_of_ctors : org = 0x00400000 
} 

SECTIONS { 
... 
.ctors : {} > start_of_ctors 
.dtors : {} > start_of_ctors // .dtors will start at the end of .ctors 
} 

_ctors will be the first address in .ctors and _dtors will be the first
byte in .dtors.

I think you are right about the PB board not having enough memory for 
C++ code. But it's wierd that only _ctors and _dtors are ones outside 
of memory range. Everything else seems to be within bound when I view 
the global variables address.
