Emulated/Translated CM Code
NM Breakpoints in Translated Code
NM Breakpoints in Translated Code
The following discussion assumes that the current Debug mode is NM (prompt is:
$nmdebug > ).
NM breakpoints can be set at every instruction within translated code even if the
instruction is not at a node point.
This allows careful inspection of the actual sections of NM translated code.
NOTE Portions of the CM state may be undefined or incorrect when a NM
breakpoint is encountered between node points.
For example, the following commands set two breakpoints. The first is at a node point, and
the second is not at a node point:
$nmdebug > B $1c.34d4
$nmdebug > B $1c.34ec
