This one?
@ FIXME: ARMARM says 'add   sp, sp, #32'
@ CHECK: add    sp, #32             @ encoding: [0x08,0xb0]

No, I haven't fixed that yet (in any patch).

This patch is just implementing "Encoding T1 is preferred to encoding T2 if <Rd> is specified and encoding T2 is preferred to encoding T1 if <Rd> is omitted." (ARMARM v7-A/R rev C.c page A8-307)
