Bug #: 14875
Summary: Disassembling m68k shows scales which the m68000 does
not support
Product: binutils
Version: 2.23
Status: NEW
Severity: minor
Priority: P2
Component: binutils
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
The M68000 chip does not support scales in the "Memory Indirect Preindexed"
mode. objdump should not display the scale if disassembling of the M68000 is
requested via -mm68k:68000
Also a minor thing is that the offsets are printed with too many leading zeros.
