The ARM processor (Thumb-2), part 20: Code walkthrough

As is traditional, I wrap up the processor overview series with an annotated walkthrough of a simple function. Here’s the function again:
extern FILE _iob[];

int fclose(FILE *stream)
{
int result = EOF;

if (stream->_flag & _IOSTRG) {
stream->_flag = 0;
