A const can be used as array size. Then if the const is not present
on all arches, compiler will produce an error about 0-sized-array.
There is no easy way to work around this for a user.
Use value of 1 for missing consts. It's just a bit safer.
Using a build tag to exclude files for golangci-lint
reduces memory consumption (it does not parse them).
The naive attempt with skip-dirs did not work.
So add codeanalysis build tag and use it in auto-generated files.
Update #977
This change adds compiler support for complex path
expressions in len targets. E.g. it allows to refer
to a sibling field as len[parent_struct:field:another_field].
See the docs change for details.
This is just a compiler change.
The feature is not yet supported by the prog package.
This prepared for handling of bytesize[parent:foo:bar] expressions
by allowing multiple identifiers after colon.
No functional changes for now, just preparation for storing more
than one identifier after colon.
For some bug types kernel produces traceback of all CPUs
(which is presumably useful for these crashes).
However, we currently throw it away because it has context
different from the oops context.
Detect such traceback and preserve output.
On powerpc, the "stat" syscall is implemented by "sys_newstat" entry point.
This causes a test failure as we can't find "sys_stat" in kallsyms.
Add "stat" -> "newstat" to the kallsyms rename map to work around this.

After commit 9ad9ef29ca
we started saying "your command '3' is accepted"
because we use numbers now. Keep string representation
of the command when parsing and use it in reply emails.
2 recent commits conflict and cause test 380 to fail:
pkg/report: improve warning titles
pkg/report: Handle powerpc stack traces correctly
Currently 380 is detected as "WARNING in program_check_exception"
rather than the expected "WARNING in assert_slb_presence".
The reason is that we started parsing WARNING stack trace and applying
proper skip patterns to frames.
Adjust WARNING matching and skip common powerpc WARNING frames.
powerpc stack traces are printed a bit differently from x86 stack traces.
Adjust the regexes accordingly to cope with this format.

Enable the Linux builder for ppc64le.
For ppc64le, we use zImage rather than bzImage as our kernel target. Pass
through the target architecture to buildKernel() so we can pick the right
target based on arch.

Add support for generating ppc64le pseries disk images. This will create a
disk image with a PowerPC PReP boot partition at the start, and install
the IEEE1275/OpenFirmware version of GRUB.
If we ever support the powernv platform in the future we're going to have
to do something different here.
Add a command line argument to specify architecture, defaulting to amd64.

Limit the amount of bisection chunks to 8. Going over this value probably
means that we are bisection a flaky crash, and continuing bisection would
just take a lot of time and likely produce no result.
Not using `elif GOOS_freebsd' since it could cause breakage on other *BSDs
due to unused variables.
Regression introduced in commit c7c3f772 (executor: improve setup for packet
handling on *BSD).
Most probably limited to input validation for now. In the future, it
could be extended to provide a bootable kernel during vm create (/bsd)
and turn vmid into a proper resource.
The OpenBSD VMs on GCE does support vmm(4).
Improve the handling of packets by:
* setting the local MAC address.
* configuring the local IPv4 address with prefix /24.
* adding an entry in the arp cache for the remote IPv4 address.
* adding an entry in the IPv6 neighbour cache for the remote
IPv6 address.
Allow 2000 ms of waiting time for syz_usb_connect and and the same time for
the whole program is this syzkall is present. Allow 200 ms of waiting time
for syz_usb_disconnect. Remove sleep from syz_usb_control_io.
