Bug #: 14020
Summary: ARM: objdump wrongly disassembles illegal pc-relative
T3 or T4 encodings of STR as valid
Product: binutils
Version: 2.22
Status: NEW
Severity: minor
Priority: P2
Component: binutils
AssignedTo: unassig...@sourceware.org
ReportedBy: albert.u.b...@aribaud.net
Classification: Unclassified
Objdump displays ARM instructions of the form 0xf84fnnnn or 0xf8cfnnnn as
"str.w rN,[PC, -nnn]" whereas these forms are illegal encodings of STR, T4 and
T3 respectively. These instructions should be decoded as e.g. ".inst ..." to
let readers know the instructions are undefined.
