--- Comment #14 from Martin Nowak <c...@dawg.eu> ---
Bit-bending I/O is a counter-example against the "no performance needed"
argument, but I still think this can be achieved easily enough with the
existing tools, i.e. by inlining the asm code in your hot loop or writing an
asm function.
for (uint i = 0; i < 32; ++i)
{
if (data & 1)
asm { mov r0, #1; str r0, [r3]; }
else
asm { mov r0, #2; str r0, [r3]; }
data >>= 1;
}
Compiler intrinsics for volatile loading/storing could be implemented with zero
overhead and it would be useful for at least one other cases (forced float
rounding to fix excess precision). So I favor this solution, but until then
core.atomic can be used.
