NAME

       yasm_dbgfmts - Yasm Supported Debugging Formats

SYNOPSIS

       yasm -g dbgfmt ...

DESCRIPTION

       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 symbols).

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

CV8

       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.

DWARF2

       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.

NULL

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

STABS

       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.
