DWARF is a widely used, standardized debugging data format. DWARF was originally designed along with Executable and Linkable Format (ELF), although it is independent of object file formats. The name is a medieval fantasy complement to "ELF" that has no official meaning, although the backronym 'Debugging With Attributed Record Formats' was later proposed.〔 ==History== The first version of DWARF proved to use excessive amounts of storage, and an incompatible successor, DWARF-2, superseded it and added various encoding schemes to reduce data size. DWARF did not immediately gain universal acceptance; for instance, when Sun Microsystems adopted ELF as part of their move to Solaris, they opted to continue using stabs, in an embedding known as "stabs-in-elf". Linux followed suit, and DWARF-2 did not become the default until the late 1990s. The DWARF Workgroup of the Free Standards Group released DWARF version 3 in January 2006,〔 〕 adding (among other things) support for C++ namespaces, Fortran 90 allocatable data and additional compiler optimization techniques. The DWARF committee published version 4 of DWARF, which offers "improved data compression, better description of optimized code, and support for new language features in C++", in 2010.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DWARF」の詳細全文を読む スポンサード リンク
