Sorry. That one was my fault. Indeed objdump now flags loads and stores as
UNPREDICTABLE that should be. It appears that it also flags some as
UNPREDICTABLE that are not. See these 3...
% ./objdump -b binary -m armv4t -D aaa23
test: file format binary
Disassembly of section .data:
00000000 <.data>:
0: 004f00b0 strheq r0, [pc], #0 ; <UNPREDICTABLE>
4: 005f00b0 ldrheq r0, [pc], #0 ; <UNPREDICTABLE>
Why are those UNPREDICTABLE?
