If a test is marked as a flake then it will be tried five times before
giving up.
Works around the problem of needing to babysit CI once a PR is pushed.
As long as we have all the flake tests marked.
Termux uses defines for these, so our token pasting fails, but we also
still want to use their define so we can fall down their emulation
library whenever possible.
Prefix an underscore to be able to use both our number definitions and
their defines in the same file.
For these unit tests we no longer need to put them in the disabled tests
file. Instead it will be skipped if the host doesn't support the feature
required.
Necessary for tests that depend on the state of the running context.
Since we support an SSE mode and an AVX mode, the FPR store truncate
test will fail on hosts that don't support AVX as the register offsets
are going to be different between the two. So we can conditionally
enable support for these tests.
Check for qemu and box binfmt_misc file conflicts before the
`binfmt_misc` install command.
This ensures if you're building from source that you won't inadvertently
install conflicting binfmt_misc files, breaking program execution.
Instead of relying on runner features, classify based on CPU features.
This fixes an annoying issue where if running unit tests locally without
it set then you get an unexpected failure.

The final tail of the file reading was incorrect, so our hashing was
"correct" but it was using stale data from the previous block size read.
Noticed this while wiring up the CI rootfs fetching since the hashing is
a lot simpler there.
Now instead of reading a tail, just attempt to read the full block size
and use the resulting data size instead. Confirmed it matches expected
results now.
In the process we are going to need to update hyperlinks and hashes
anyway, change the hash to XXH3 so it is faster to run.
According to PEP 386: https://www.python.org/dev/peps/pep-0386/
distutils is deprecated and will be removed in an upcoming python
version.
Switch over to pkg_resources for version parsing and comparison
Allows some something like the following:
"Env": {
"FEX_MAXINST": "500"
}
Not that I would recommend overriding MAXINST in the asm tests, as
command line overrides that
cmake will bake in the environment variable in to the build scripts.
Instead have the guest_test_runner fetch it at runtime.
This means if you forget to set ROOTFS prior to running cmake, you can
now set it afterwards and rerun with just ctest instead of a cmake
dance.
Fixes#315
This is definitely a bit divisive but overall this is a win.
This is a user pattern that is emerging in a bunch of projects.
Allow an officially sourced script that lets you pipe a script directly
in to python/bash and setup the environment entirely.
This only supports Ubuntu {20.04, 21.04, 21.10, 22.04} which matches
exactly what we expose in the PPA.
Once this is in the repo, and our PPA is updated to the latest release
tag you can run this script like:
`curl --silent <Direct Github raw link> | python3`
Once the PPA is updated, the README and Wiki will be updated with Quick
Start guides to use this path.
The script steps
1) Checks if ARMv8, or fail
2) Checks if supported Ubuntu, or fail
3) Checks if PPA installed
3a) Install PPA if not, or fail
4) Check if packages are installed
4a) Install non-installed packages, or fail
5) Check if RootFS is configured/exists
5a) Run through FEXRootFSFetcher to get/setup rootfs, or fail
6) Attempt to run emulated uname -a through FEX, or fail
7) Provide some examples for how to use FEX
8) Exit with success!
This is very useful for extracting function definitions for thunks.
Keep it in upstream to not get lost.
Sometimes it can munge a definition but it is usually fine.
