The assembler defines bit masks for each of the bits in the IA-64
|
||
|
|
processor status register. For example, ‘<samp><span class="samp">psr.ic</span></samp>’ corresponds to
|
||
|
|
a value of 0x2000. These masks are primarily intended for use with
|
||
|
|
the ‘<samp><span class="samp">ssm</span></samp>’/‘<samp><span class="samp">sum</span></samp>’ and ‘<samp><span class="samp">rsm</span></samp>’/‘<samp><span class="samp">rum</span></samp>’

|
|
instructions, but they can be used anywhere else where an integer
|
||
|
|
constant is expected.
