In pipe mode, session->header.env.arch is not populated until the events
are processed. Therefore, the following command crashes:
perf record -o - | perf script
(gdb) bt
It fails when we try to compare env.arch against uts.machine:
if (!strcmp(uts.machine, session->header.env.arch) ||
(!strcmp(uts.machine, "x86_64") &&
!strcmp(session->header.env.arch, "i386")))
native_arch = true;
In pipe mode, it is tricky to find env.arch at this stage. To keep it
simple, let's just assume native_arch is always true for pipe mode.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
