`--enable-unsigned-xori'
|
|
`--disable-unsigned-xori'
|
|
Historically, `l.xori', has sign extended its operand. This is
|
|
inconsistent with the other logical opcodes (`l.andi', `l.ori'),
|
|
but in the absence of `l.not', it allows a register to be inverted
|
|
in a single instruction using:
|
|
|
|
`l.xori rD,rA,-1'
|
|
|
|
This flag causes Or1ksim to treat the immediate operand as
|
|
unsigned (i.e to zero-extend rather than sign-extend).
|
|
|
|
The default is to sign-extend, so that existing code will continue
|
|
to work.
|
|
|
|
Caution: The GNU compiler tool chain makes heavy use of this
|
|
instruction. Using unsigned behavior will require the
|
|
compiler to be modified accordingly.
|
|
|
|
This option is provided for experimentation. A future
|
|
version of OpenRISC may adopt this more consistent behavior
|
|
and also provide a `l.not' opcode.
