<code>as</code> supports AMD's Trailing Bit Manipulation (TBM)
|
||
|
|
instruction set, available on AMD's BDVER2 processors (Trinity and
|
||
|
|
Viperfish).
|
||
|
|
|
||
|
|
<p>TBM instructions provide instructions implementing individual bit
|
||
|
|
manipulation operations such as isolating, masking, setting, resetting,
|
||
|
|
complementing, and operations on trailing zeros and ones.
