<p>The assembler defines bit masks for each of the bits in the IA-64
|
||
|
|
processor status register. For example, ‘<samp>psr.ic</samp>’ corresponds to
|
||
|
|
a value of 0x2000. These masks are primarily intended for use with
|
||
|
|
the ‘<samp>ssm</samp>’/‘<samp>sum</samp>’ and ‘<samp>rsm</samp>’/‘<samp>rum</samp>’
|
||
|
|
instructions, but they can be used anywhere else where an integer
|
||
|
|
constant is expected.
