• -convert {big_endian, cray, fdx, fgx, ibm, little_endian, native, vaxd,

vaxg} options (new functionality)

• support for ‘-assume [no]accuracy_sensitive’(mapsto+O[no]fltacc). Tru64-mode

default is accuracy_sensitive

• support for ‘-assume [no]dummy_aliases’(mapsto+O[no]parmsoverlap)

• support for ‘-inline {all|none|speed}’ options (‘all’and‘speed’mapto+Oinline;

‘none’mapsto+Onoinline)

• support for ‘-speculate {all|none}’options(‘all’mapsto+Ostatic_prediction,

‘none’mapsto+Onostatic_prediction)

• -[no_]fp_reorder (inverse of ‘-assume [no]accuracy_sensitive’)

• -[no]omp (maps to +O[no]openmp)
