will make sure the current course of action is completed from the CPU, ahead of A different system accesses the variable

The syntax and semantics are presently properly-outlined by other excellent answers to this query. Because execution

But for UP (And perhaps MP), If a timer interrupt (or IPI for SMP) fires in this modest window of LDREX and STREX, Exception handler executes possibly alterations cpu context and returns to The brand new activity, having said that the shocking portion is available in now, it executes 'CLREX' and therefore eliminating any special lock held by earlier thread. So how superior is using LDREX and STREX than LDR and STR for atomicity on the UP process ?
