  Debugging Options - Using the GNU Compiler Collection (GCC)
This is the format used by DBX on IRIX 6.
Emit debug information for struct-like types only when the base name of the compilation source file matches the base name of file in which the type was defined, unless the struct is a template or defined in a system header.
This is used for debugging the RTL-based passes of the compiler.

 Debugging Format Interoperability - Open Watcom
This format was used by early releases of Visual C++ and is publicly documented.
It supports both 16-bit and 32-bit debugging, although 32-bit tools using this format are extremely rare since it was only used for early (when OS/2 was still under joint development with IBM and Microsoft) OS/2 2.0 development.
IBM OS/2 debuggers understand this format, and it is very similar to IBM HLL; in fact IBM's NB04 style debug data may contain both IBM HLL and pre-CV4 CodeView data (this would happen in mixed 16/32-bit executables).

As output format i have to use the ELF-Format, non relocateable, debugging info in the load module.
When i check it with the readelf-command i can see the debugging sections.debug and.line which should be a proof that it isnt stipped.(And they contain something) The sections.debug and.line give the hint that there is the DWARF1.1 format present.

ARM Symbolic Debug Table Format =============================== Acknowledgement --------------- This design is based on work originally done for Acorn Computers Ltd. by Topexpress Ltd. Introduction ------------ This document specifies the format of symbolic debugging data generated by ARM compilers, which is used by the ARM Symbolic Debugger () to support high level language oriented, interactive debugging.
Debugging data are position independent, containing only relative references to other debugging data within the same section, and relocatable references to other compiler-generated areas.
When the same structure is used to map debugging data in memory, an offset field may be used to hold a pointer to another debug item in memory, rather than the offset of it in the debug area.

 Info: (gcc) Debugging Options
That debug format is long obsolete, but the option cannot be changed now.
This is used for debugging the RTL-based passes of the compiler.
Most debug dumps can be enabled either passing a letter to the `-d' option, or with a long `-fdump-rtl' switch; here are the possible letters for use in LETTERS and PASS, and their meanings: `-dA' Annotate the assembler output with miscellaneous debugging information.

 Documentation for GNU compilers - 3.9 Options for Debugging Your Program or GCC
On most systems that use stabs format, -g enables use of extra debugging information that only GDB can use; this extra information makes debugging work better in GDB but will probably make other debuggers crash or refuse to read the program.
-gdwarf-2 does not accept a concatenated debug level, because GCC used to support an option -gdwarf that meant to generate debug information in version 1 of the DWARF format (which is very different from version 2), and it would have been too confusing.

 Xcode 2.4 Release Notes   (Site not responding. Last check: 2007-10-22)
Stabs is still available and is still the default debugging format, but DWARF may be chosen as an alternative format.
Debugging with DWARF information stores all debug information in the object files and creates a debug map in the final executable or shared library runtime file.
The Xcode 2.3 and Xcode 2.4 file format and build system are backwards compatible with Xcode 2.1, Xcode 2.2, and Xcode 2.2.1, but this does not extend to new features in Xcode 2.3 and Xcode 2.4 or Xcode features that have problems in earlier versions.

 Debugging Options
Options for Debugging Your Program or GNU CC ============================================ GNU CC has various special options that are used for debugging either your program or GCC: `-g' Produce debugging information in the operating system's native format (stabs, COFF, XCOFF, or DWARF).
`-ggdb' Produce debugging information in the native format (if that is supported), including GDB extensions if at all possible.

Statements are independent: if you stop the program with a breakpoint between statements, you can then assign a new value to any variable or change the program counter to any other statement in the function and get exactly the results you would expect from the source code.
*It also makes debugging impossible on some machines.* On some machines, such as the Vax, this flag has no effect, because the standard calling sequence automatically handles the frame pointer and nothing is saved by pretending it doesn't exist.
You will not be able to use `gprof' on all systems if you specify this option and you may have problems with debugging if you specify both this option and `-g'.

 Standards and specs: An unsung hero: The hardworking ELF
Executable formats and object formats are closely related; both are intended to store machine code in a way that allows other programs to identify the code and refer to it.
Object formats need to provide enough information to allow a linker to assemble an executable from them; executable formats may not need this, but often provide it anyway.
Files in the ELF format are compatible with tools that manipulate ELF files and in some cases, this holds true across architectures.
