Your statement is barely genuine for architectures that give this kind of warranty of atomicity for outlets and/or loads. There are actually architectures that do not make this happen.
– H2ONaCl Commented Dec 6, 2022 at one:37 yeah, that's good. I suppose my stage is that men and women may possibly study "instantaneous" and by analogy with ordinary expectations of linear time, make the bounce to assuming linearizability - the place if one Procedure happens in advance of Yet another, the thing is the effects in that buy also. Which isn't a guarantee specific atomic functions supply when put Atomic Wallet together.
They sometimes come from modifications for the database, Whilst it could seem to be less complicated to widen a column and use it to things a number of values as an alternative to including a normalized associated desk (which frequently breaks current programs).

But for UP (and possibly MP), If a timer interrupt (or IPI for SMP) fires In this particular little window of LDREX and STREX, Exception handler executes quite possibly adjustments cpu context and returns to The brand new job, on the other hand the shocking portion is available in now, it executes 'CLREX' and hence eliminating any special lock held by prior thread. So how superior is using LDREX and STREX than LDR and STR for atomicity on the UP process ?
atomicity of one home also are unable to guarantee thread safety when a number of dependent Houses are in Participate in.
