How to enable Intel Processor Trace support?

[Willgerodt, Felix]

Hello Simon,

The documentation for all recording modes can be found here:
https://sourceware.org/gdb/onlinedocs/gdb/Process-Record-and-Replay.html

You can find the configure options for gdb in the configure script in the gdb folder.
You can pass all flags you find there to the top-level configure script.

For me gdb/configure --help shows these options:

--with-intel-pt         include Intel Processor Trace support (auto/yes/no)
--with-libipt-prefix[=DIR]  search for libipt in DIR/include and DIR/lib
--without-libipt-prefix     don't search for libipt in includedir and libdir
--with-libipt-type=TYPE     type of library to search for (auto/static/shared)

Regards,
Felix
