But for UP (And perhaps MP), If a timer interrupt (or IPI for SMP) fires On this little window of LDREX and STREX, Exception handler executes possibly changes cpu context and returns to The brand new process, nonetheless the shocking aspect comes in now, it executes 'CLREX' and therefore eradicating any distinctive lock held by prior thread. So how better is working with LDREX and STREX than LDR and STR for atomicity on the UP procedure ?
