YASM_DBGFMTS(7)		 Yasm Supported	Debug Formats	       YASM_DBGFMTS(7)

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.
