ContactHI-TECH Support if this is not handwritten assembler code.(471) recursive function calls: (Linker)These functions (or function) call each other recursively. One or more of these functions has staticallyallocated local variables (compiled stack). Either use the reentrant keyword (if supportedwith this compiler) or recode to avoid recursion, e.g.:int test(int a){if(a == 5)return test(a++); /* recursion may not be supported by some compilers */return 0;}(472) function * appears in multiple call graphs: rooted at * and * (Linker)This function can be called from both main-line code and interrupt code.
