The ARM Thumb2 pseudo-instruction
PKHTB<c> <Rd>,<Rm>,<Rn>
should be assembled through
PKHBT<c> <Rd>,<Rm>,<Rn>
but is instead assembled through
PKHBT<c> <Rd>,<Rn>,<Rm>
For example:
$ echo ".code 16 pkhtb r1,r2,r3" | arm-elf-as -aln -EB -o /dev/null
1 0000 EAC20103 .code 16 pkhtb r1,r2,r3
$ echo ".code 16 pkhbt r1,r2,r3" | arm-elf-as -aln -EB -o /dev/null
1 0000 EAC20103 .code 16 pkhbt r1,r2,r3
