1 9.9.1 D10V Options
1 ------------------
1
1 The Mitsubishi D10V version of 'as' has a few machine dependent options.
1
1 '-O'
1 The D10V can often execute two sub-instructions in parallel. When
1 this option is used, 'as' will attempt to optimize its output by
1 detecting when instructions can be executed in parallel.
1 '--nowarnswap'
1 To optimize execution performance, 'as' will sometimes swap the
1 order of instructions. Normally this generates a warning. When
1 this option is used, no warning will be generated when instructions
1 are swapped.
1 '--gstabs-packing'
1 '--no-gstabs-packing'
1 'as' packs adjacent short instructions into a single packed
1 instruction. '--no-gstabs-packing' turns instruction packing off
1 if '--gstabs' is specified as well; '--gstabs-packing' (the
1 default) turns instruction packing on even when '--gstabs' is
1 specified.
