Bug ID: 24907
Summary: Objdump produces wrong branch opcode interpretation in
some cases
Product: binutils
Version: 2.33 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: itayzac89 at gmail dot com
Target Milestone: ---
Bug explained in details in the stack overflow URL
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: e03a b.n 78 <func+0x78>
Now, the opcode e03a in the target system (ARMv6-M) says jump to the location
of PC + 0x78. A correct interpretation will be:
3c: e03a b.n B4 <func+0xB4>
It happens each time the jump is between jumps, that are subject to relocation
like here:
38: f7ff fffe bl 0 <log_func>
3c: e03a b.n 78 <func+0x78> <---- PROBLEM IS HERE
3e: f7ff fffe bl 0 <func>
or here
6a: f7ff fffe bl 0 <log_func>
6e: e021 b.n 46 <random_delay+0x46> <--- ALSO HERE
70: f7ff fffe bl 0 <random_delay>
