#163 closed defect (fixed)

librdbg for m68k fails on systems with VBR

Reported by: thomas.doerfler Owned by: thomas.doerfler
Priority: lowest Milestone: 2
Component: unspecified Version: unknown
Severity: normal Keywords:
Cc: bugs@…, joel.sherrill@… Blocked By:


The file rdbg_cpu_asm.S incorrectly assumes, that exception stack frames on M68K members with VBR always are 6 byte long.

This results in some gdb commands like "next" to fail.


M68k systems with VBR (e.g. MC68360)

Build system for a MC68360 with librdbg support
try debugging session with m68k-RTEMS-gdb
set and hit breakpoint to some function
try to skip over some subfunctions with "next" command
