0b00, 0b10 are written by device?
I suppose device can only clear high bit, can keep low bit no change.
Then the value written by device can be either 0b01 or 0b00, but 0b10 means to set high bit, no?

[LLVMdev] Definition of RegisterClass for load instruction in Thumb2
...ions of target RegisterClass (outs) are different in t2LDRSB and t2LDRSB_PRE. While t2LDRSB uses rGPR, t2LDRSB_PRE uses GPR. I wonder if lr and pc are already prevented from being allocated in pre-indexing case, because of some register hint that is being enforced?

reversing the effects of mkfs.btrfs?
I was playing around with btrfs, and did a mkfs.btrfs on one of my
partition. Mistakes, it was my data partition (ext3 based).
I have not yet mounted the device, but the mkfs.btrfs continued to
completion.
Is it possible to salvage my ext3 filesystem? Anyway to reverse the
effect of mkfs.btrfs?
Thank you for your help/answer.

How are alternate superblocks repaired?
Hi,
Using dumpe2fs I have been able to determine that all of my alternate ext3 superblocks are corrupted (not clean), and only the primary superblock is valid, i.e. mount works and the ordered journal is applied. When the primary superblock gets flakey, i.e. the ext_attr Filesystem feature goes missing - not sure why this occurs. At this point, the mount does not apply the journal using the
