Summary: [ARM disasm] some moves to/from PC are disassembled as
invalid
Product: new-bugs
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs
AssignedTo: [email protected]
ReportedBy: [email protected]

The following opcodes are valid ARM instructions but are not recognized by the
disassembler (they are all disassembled as invalid):
e59ff018 ldr pc, [pc, #24]
01a0e00f moveq lr, pc
e1a0f001 mov pc, r1
So these commands output an error message:
$ echo '0x18 0xf0 0x9f 0xe5' |llvm-mc -disassemble -arch=arm
$ echo '0x0f 0xe0 0xa0 0x01' |llvm-mc -disassemble -arch=arm
$ echo '0x01 0xf0 0xa0 0xe1' |llvm-mc -disassemble -arch=arm
