High Quality Content by WIKIPEDIA articles! XCOFF, for "eXtended COFF", is an improved and expanded version of the COFF object file format defined by IBM and used in AIX. Early versions of the PowerPC Macintosh also supported XCOFF, as did BeOS. XCOFF additions include the use of csects to provide subsection granularity of cross-references, and the use of stabs for debugging. Information for the handling of shared libraries is also more elaborate than for plain COFF. More recently, IBM defined an XCOFF64 version supporting 64-bit AIX, and used XCOFF32 to mean the original file format. The Common Object File Format (COFF) is a specification of a format for executable, object code, and shared library computer files used on Unix systems. It was introduced in Unix System V, and formed the basis for extended specifications such as XCOFF and ECOFF, before being largely replaced by ELF, introduced with SVR4.
