some cases
Product: binutils

https://stackoverflow.com/questions/57477494/objdump-produces-wrong-branch-opcode-interpretation
Basically, objdump procude wrong branch opcode interpretation in some cases,
for example, see the following objdump line of a specific object file of a
specific function (func):
3c: e03ab.n 78
Now, the opcode e03a in the target system (ARMv6-M) says jump to the location
of PC + 0x78. A correct interpretation will be:
3c: e03ab.n B4
It happens each time the jump is between jumps, that are subject to relocation
like here:
38: f7ff fffe bl 0
3c: e03ab.n 78< PROBLEM IS HERE
3e: f7ff fffe bl 0
or here
6a: f7ff fffe bl 0
6e: e021b.n 46 <--- ALSO HERE
70: f7ff fffe bl 0
