• -names {uppercase|lowercase} (alternate for +[no]uppercase)
• -[no]altparam (-Wc, -dps)
• -what (alternate for +what)
• +[no]padsrc flag (not restricted to Tru64 mode). HP mode default is +padsrc
• -check [no]bounds options (for example, -[no]check_bounds)
• -assume [no]backslash options (opposite of +[no]escape; Tru64 default different from
HP)
• -assume [no]{buffered_io, recl, minus0} options (new functionality)
• -assume [no]underscope options (for example, +[no]ppu)
• -check [no]{format, output_conversion} options (new functionality)
• -convert {big_endian, cray, fdx, fgx, ibm, little_endian, native, vaxd,
vaxg} options (new functionality)
• support for ‘-assume [no]accuracy_sensitive’ (maps to +O[no]fltacc). Tru64-mode
default is accuracy_sensitive
• support for ‘-assume [no]dummy_aliases’ (maps to +O[no]parmsoverlap)
• support for ‘-inline {all|none|speed}’ options (‘all’ and ‘speed’ map to +Oinline;
‘none’ maps to +Onoinline)
• support for ‘-speculate {all|none}’ options (‘all’ maps to +Ostatic_prediction,
‘none’ maps to +Onostatic_prediction)
• -[no_]fp_reorder (inverse of ‘-assume [no]accuracy_sensitive’)
• -[no]omp (maps to +O[no]openmp)
• -[no]pipeline (maps to +O[no]pipeline)
•-nospeculate (alternate of ‘-speculate none’)
• -[no]transform_loops (maps to +O[no]loop_transform)
• -[no]member_alignment options (alternate spelling of ‘-align [no]records’)
• -math-library {accurate|fast} options (‘accurate’ maps to +nofastintrinsics;
‘fast’ is a no-op)
• -reentrancy {none|threaded} and -noreentrancy options; these are recognized and
ignored by the compiler.
• -noD and -nov options; recognized and ignored.
