Patches 5-6 are comment or documentation fixes.\nPatch 7 adds mode transitions to dump output (this can wait till stage 1).\nAll of the patches can be applied independently.\n\nOk for master? And ok to backport patches 2-6 to GCC 14/15?\n\n\n\n\nThe patch 3 bug has been discovered and reported independently at least three\ntimes that I've seen. While investigating this (and reading most of the ZA\nmode switching logic in depth), I identified the patch 2 and 4 bugs. My\noriginal attempt at writing a testcase for patch 2 exposed the patch 1 bug.\n\nI think these patches address all the wrong-code bugs in the ZA state\ntransition logic. However, there is still room to optimise the mode\ntransitions further - for example, it would be better to delay a transition out\nof INACTIVE_CALLER state until after a private ZA function, if ZA is not used\nbefore the call.\n\nAlice" }
