Fix 32-bit Arm reg classes by hierarchically sorting them We were rejecting legal `asm!` because we were asking for the "greatest" feature that includes a register class, instead of the "least" feature that includes a register class. This was only revealed on certain 32-bit Arm targets because not all have the same register limitations. This is a somewhat hacky solution, but other solutions would require potentially rearchitecting how the internals of parsing or rejecting register classes work for all targets. Fixes #126797 r? ``@Amanieu`` |
