* New configure options
|

|

--with-intel-pt
|
||||
This configure option allows the user to build GDB with support for
|
||||
Intel(R) Processor Trace (default: auto). This requires libipt.
|
||||
|
||||
--with-libipt-prefix=PATH
|
||||
Specify the path to the version of libipt that GDB should use.
|
||||
$PATH/include should contain the intel-pt.h header and
|
||||
$PATH/lib should contain the libipt.so library.
