DWARF plugin

DWARF plugin

The DWARF plugin will search for DWARF-encoded debug information either in the input file, or a "companion" file (using a strategy similar to that of GDB), when some is found, will extract the following:

  - type information
  - function names, prototypes, local variables
  - global variables names & types

In addition, the DWARF plugin provides source-level debugging.

Dialog box

  Global name               : create global names based on DWARF informations
  Functions                 : Create functions based on DWARF informations
  Use function bounds       : Uses DWARF to determine functions boundaries
  Types (uncheck for speed) : Create types, needed for Apply calling
                              convention or Function prototype are definitive
  Apply calling convention  : DWARF will try and guess the calling convention
                              instead of using platform default calling
                              convention. Needed for Allow __usercall
  Allow __usercall          : If DWARF detects __usercall, allow to use it. If
                              not allowed, the default calling convention for
                              the platform will be used
  Function prototypes are definitive: Decompiler will not try to change the
                                     prototype if set. Use this with caution
  Import file names/line numbers: Import all information

'cfg/dwarf.cfg' file presents in details all the options
