       yasm_dbgfmts - Yasm Supported Debugging Formats


       yasm -g dbgfmt ...


       The standard Yasm distribution includes a number of modules for different debugging
       formats. The debugging information is embedded into the object file. Use of a non-“null”
       debug format also causes Yasm to output all symbols to the object file (including local

       The debug format is selected on the yasm(1) command line by use of the -g dbgfmt command
       line option.


       The CV8 debug format is used by Microsoft Visual Studio 2005 (version 8.0) and is
       completely undocumented, although it bears strong similarities to earlier CodeView
       formats. Yasm's support for the CV8 debug format is currently limited to generating
       assembly-level line number information (to allow some level of source-level debugging).
       The CV8 debug information is stored in the .debug$S and .debug$T sections of the Win64
       object file.


       The DWARF 2 debug format is a complex, well-documented standard for debugging information.
       It was created to overcome shortcomings in STABS, allowing for much more detailed and
       compact descriptions of data structures, data variable movement, and complex language
       structures such as in C++. The debugging information is stored in sections (just like
       normal program sections) in the object file. Yasm supports full pass-through of DWARF2
       debugging information (e.g. from a C++ compiler), and can also generate assembly-level
       line number information.


       The “null” debug format is a placeholder; it adds no debugging information to the output


       The STABS debug format is a poorly documented, semi-standard format for debugging
       information in COFF and ELF object files. The debugging information is stored as part of
       the object file's symbol table and thus is limited in complexity and scope. Despite this,
       STABS is a common debugging format on older Unix and compatible systems, as well as DJGPP.
