--- Comment #8 from Kevin Bracey <kevin.bracey at alifsemi dot com> --- I'm only testing on the Linux trunk because it's what Godbolt has. If it has bare-metal, I'm not seeing it. Actual real development system is bare-metal using Arm's embedded GCC releases, and I don't have a set-up to test a trunk GCC build on it at the moment. Clearly Helium+Linux on Godbolt is a bit confused because it's always using non-existent registers Q8 upwards. There may be a fundamental config error leading to all sorts of strange results. (Mostly reproduces my bare-metal findings though.)
