Looks plausible, but (a) your commit message doesn't make it clear that this bug only applies to SWI on M profile cores, not AR, and (b) could probably use the comment that is present in the AR-core equivalent of this code: /* The PC already points to the next instruction. */ This is one of those "surprised nobody's noticed this one before" bugs, do the RTOSes we've tested with really not use SWI? -- PMM
