RealView Debugger User Guide - ARM Information Center

Working with Macros9.1.1 Properties of macrosMacros can:• have return values• contain C expressions• contain certain C statements• have arguments• define macro local variables• use conditional statements• call other macros and predefined macros• be used in expressions, where they return values• reference target variables and registers• reference user-defined variables, in debugger or target memory• execute most debugger commands• be defined in a debugger include file.Macros cannot:• be recursive• define global variables• define static variables• define other macros.9.1.2 Debugger commands in macrosRealView Debugger enables you to enter debugger commands on the command line, orwhen using the headless debugger, for example PRINTF or SETMEM.You can define a macro that contains a sequence of debugger commands. When used inthis way, the command must be enclosed by dollar signs ($), shown in Example 9-1.Example 9-1 Using debugger commands in macrossome_commandsdefine int registers(){some_commandsfor(macro_index = 0; macro_index < 6; macro_index++){macro_bin_str[macro_index + 8] = macro_cpsr_mode[macro_index +(6*macro_cpsr_key)];}ARM DUI 0153G Copyright © 2002-2005 ARM Limited.
