Commits 34c57a7f ("asm-mem: does it clobber memory?", 2021-02-20) and
d6721b38 ("asm-mem: does it output to memory?", 2021-02-20) both add
a single bit bitfield to the 'struct asm' part of the union contained
within the 'struct instruction'. This causes the 'selfcheck' target
to issue several 'dubious one-bit signed bitfield' errors.
In order to suppress these errors, change the type of the bitfields to
an unsigned type.
