Hi!
As it's been some time: this was the discussion about
-fstrict-volatile-bitfields (as enabled by default on SH, for example)
breaking some testsuite bits due to missed optimizations (even for
bitfields that are not volatile).

meaningless.
MCU vendors would disagree. If a location is volatile, it's most
likely hardware, and must be accessed in the user-specified way.
Randomly accessing adjacent locations could cause system failure.
