ARM has bit-banding specifically for this. I think it’s limited to M-profile CPUs (e.g. v7-M) but I’ve definitely used this before. It basically creates a 4-byte virtual address for every bit in a region. So the CPU itself can’t “address” a bit but it can access an address backed by only 1 bit of SRAM or registers (this is also useful to atomically access certain bits in registers without needing to use SW atomics).

House passed it. Doubtful that this senate will pass it. Senate still has some people looking out for themselves and knowing that cutting Medicare/Medicaid to the levels in this bill is a death sentence to their campaigns. For instance, see Sen. Hawley’s opposition to it (and Hawley is otherwise a huge POS).
