TASKING VX-toolset for ARM User Guide

Tool OptionsDefault debug informationThis provides all debug information you need to debug your application. It meets the debuggingrequirements in most cases without resulting in oversized assembler/object files.Full debug informationWith this suboption extra debug information is generated about unused typedefs and DWARF "lookuptable sections". Under normal circumstances this extra debug information is not needed to debug theprogram. Information about unused typedefs concerns all typedefs, even the ones that are not used forany variable in the program. (Possibly, these unused typedefs are listed in the standard include files.)With this suboption, the resulting assembler/object file will increase significantly.In the following table you see in more detail what DWARF information is included for the debug optionlevels.Feature-g1-g2-g3type checkRemarksbasic info++++info such as symbol name and typecall frame++++this is information for a debugger to computea stack trace when a program has stoppedat a breakpointsymbol lifetime++this is information about where symbols live(e.g. on stack at offset so and so, when theprogram counter is in this range)line number info+++file name, line number, column number”lookup tables"+DWARF sections ... this is an optimizationfor the DWARF data, it is not essentialunused typedefs+in the C/C++ code of the program there canbe (many) typedefs that are not used for anyvariable. Sometimes this can causeenormous expansion of the DWARF data andthus it is only included in -g3.Related information-307
