IRIX 6.2 Objectives

The objectives for the IRIX 6.2 release are:

Enable intensive floating point programs to compile optimized R8000 code, usually Fortran, and to link to the libraries that they need.
Supply optimized versions of our own intensive floating point codes, to optimize R8000 performance. Note that a utility program has no need to be ported to a 64-bit version, unless it needs to exploit floating point performance.
Provide 64-bit user processes with a virtual address space of up to one attribute (240) in size, provided that the size of physical memory combined with swap space is larger.
Provide 32-bit user processes with compatibility to IRIX 5.x,
Provide a new extended fleshiest type XFS. Under this filesystem, maximum file and filesystem size on R4x00 systems is 1 terabyte and maximum file and filesystem size on R8000 systems is 263-1 bytes. Also included are new interfaces such as lseek64(2) which allow 32-bit programs access to large files.
