Description uros 2003-07-23 07:28:00 UTC 
[Converted from Gnats 1295]

in gdb/config/h8300/tm-h8300.h, NUM_REGS is #defined to 14, and gdbsim_fetch_register() calls sim_fetch register() functions with values from 0 .. 13.

In sim/h8300/compile.c, around line 1998, we have:
if (!h8300smode && rn >=EXR_REGNUM)
  rn++;

which now increases rn from 13 to 14. And because there is no register witn index 14, abort() in sim_fetc_register() is triggered.

Release:
gdb-5.3
Comment 1 uros 2003-07-23 07:28:00 UTC 
Fix:
change "abort();" in sim/h8300/compile.c, function sim_fetch_register(), line 2003 to "return 0;"
(Perhaps also the abort() in sim_store_register() should be changed to "return 0;" ?)
Comment 2 Mike Frysinger 2015-11-22 08:06:03 UTC 
this was fixed in commit dc5c3759e035d47d00088e43ea5871ffe717eb02 to issue a warning and return 0 instead of calling abort
