GDB cannot step through DBNZ
Closed this issue · 2 comments

If you step over the DBNZ instruction, the debugee will crash. Probably because the debugger inserts the wrong breakpoint at the wrong place.
Affects all HS4/5/6 targets.
sample: gdb-dbnz-lnx.tgz

The fix from @kolerov is upstream:
arc: Put DBNZ instruction to a separate class
arc: Determine a branch target of DBNZ correctly
@kolerov Please cherry-pick your patches from upstream for the relevant (release) branches and then close this issue.

There are no next release branches for ARC classic. Thus, I reverted old version of those patches in arc64 and pushed upstream versions (they are slightly different).
