B.2 Sun Studio 11 Fortran Release

• New -xmodel option:The new -xmodel option lets you specify the kernel, small, or medium memory models on the 64-bit AMD architecture. If the size of your global and static variables exceeds two gigabytes, specify -xmodel=medium. Otherwise, use the default -xmodel=small setting. See 3.4.150 –xmodel=[small | kernel | medium].

• The -xvector option extended for x86 SSE2 platforms:The -xvector option enables automatic generation of calls to the vector library functions and/or the generation of the SIMD (Single Instruction Multiple Data) instructions. This option now offers the expanded syntax on x86 SSE2 platforms. See 3.4.181 –xvector[= [[no%]lib, [no%]simd, %none] ].

• STACKSIZE environment variable enhanced:The syntax of the STACKSIZE environment variable has been enhanced to include a units keyword.

• -xpagesize options available on x86 platforms:Options -xpagesize, -xpagesize_heap, and -xpagesize_stack are now enabled on x86 platforms as well as SPARC. See 3.4.157 –xpagesize=size.

• New UltraSPARC T1 and UltraSPARC IV+ targets enabled:Values for -xarch, -xchip, -xcache, and -xtarget support new UltraSPARC processors. See 3.4.177 –xtarget=t.
