Working with Breakpoints4.1.6 Viewing breakpoints in your code viewBreakpoints are marked in the source-level and disassembly-level view in the graymargin, at the left side of the window. Standard software and hardware breakpoints areidentified by a disc icon, which is color-coded to reflect the type (see Breakpoint typeson page 4-2) and status of the breakpoint:RedYellowWhiteA red icon shows that you have set an unconditional breakpoint, and thatthe breakpoint is enabled.A yellow icon shows that you have set a conditional breakpoint, and thatthe breakpoint is enabled. The conditions are software conditions that arecontrolled by RealView Debugger. Although hardware breakpoints canhave conditions that are controlled in hardware, only when the softwareconditions are assigned are these breakpoints conditional in RealViewDebugger.A white icon shows that you have disabled an existing breakpoint. Whenyou re-enable the breakpoint, the icon changes back to the color it hadbefore the breakpoint was disabled.This color coding is also reflected in the Break/Tracepoints pane.NoteHardware access, read, and write breakpoints are not shown in the File Editor pane,because there is no specific line or context to display them.If you try to set a breakpoint on a non-executable line, RealView Debugger looks for thefirst executable line immediately following and places the breakpoint there. If the linespreceding the breakpointed instruction are comments, declarations, or othernon-executable code, they are marked with black, downward pointing arrows. Linesmarked in this way are regarded as part of the breakpoint.Multiple breakpoints units on a single lineIf you have set multiple breakpoint units on a source line containing multiple statementsor on inline functions, then disabling the first breakpoint unit changes the marker disc,shown in Figure 4-1 on page 4-11. If you disable the second breakpoint unit on the line,the marker remains.4-10 Copyright © 2002-2005 ARM Limited. All rights reserved. ARM DUI 0153G
