CHAPTER 9: DEBUGGER

9.8.2 Source Display and Symbolic Debugging Function

The debugger allows program debugging while displaying the assembly source statements. Address

specification using a symbol name is also possible.

Displaying program code

The [Source] window displays the program in the specified display mode. The display mode can be

selected from among the three modes: Unassemble mode, Source mode, Mix mode.

Mix m[View | Program | Mix Mode]

(1) Unassemble mode

In this mode, the debugger displays the program codes after unassembling into mnemonics.

(2) Source mode

In this mode, the source that contains the code at the current PC address is displayed like an editor

screen. This mode is available only when an absolute object file that contains source debugging

information has been loaded.
