Eli,
thanks for your help.
I've corrected mentioned problems; see below if it is ok:

forever because it has no way of knowing how long the program is going
to run before stopping.

+ Some implementations of OpenRISC 1000 Architecture also have hardware trace.
+ It is very similar to @value{GDBN} trace, except it does not interfere with
normal
+ program execution and is thus much faster. Hardware breakpoints/watchpoint
+ triggers can be set using:
+ @table @code
+ @item $LEA/$LDATA
+ Load effective address/data
+ @item $SEA/$SDATA
+ Store effective address/data
+ @item $AEA/$ADATA
+ Access effective address ($SEA or $LEA) or data ($SDATA/$LDATA)
+ @item $FETCH
+ Fetch data
+ @end table
+
+ When triggered, it can capture low level data, like: @code{PC}, @code{LSEA},
+ @code{LDATA}, @code{SDATA}, @code{READSPR}, @code{WRITESPR}, @code{INSTR}.
+
+ @code{htrace} commands:
+ @cindex OpenRISC 1000 htrace
+ @table @code
+ @kindex hwatch
+ @item hwatch @var{conditional}
+ Set hardware watchpoint on combination of Load/Store Effecive Address(es)
+ or Data. For example:
+
+ @code{hwatch ($LEA == my_var) && ($LDATA < 50) || ($SEA == my_var) &&
