Access C/C+ variable from assembly

Question asked by Kfir Ben shimon on Jul 30, 2017



I'm having trouble accessing C/C++ variable from an assembly code.

I have used the following documentation:

assembly programming 


and tried to use something like 

ASM_KEYWORD(" la r0,branch_addr");

"Load Address (la): The la mnemonic is useful for obtaining the address of a variable specified by name" (EREFRM_2-0.pdf).


Which results in an error:

:113, Error, Unrecognized line: la r0,branch_addr



Is there another way of accessing a variable?
