This test was written to test SMC where one thread is doing execution
while the other thread is modifying.
According to the printf documentation it is supposed to "wait for code
to be modified" but actually it was testing a race between a printf on
one thread and the primary thread modifying the code.
Fix this test so it is actually waiting for code modification to happen
rather than testing a race condition. This is likely what the original
author intended.
CI is hitting this flake more frequently now because it is even faster
it seems, so fixing this test is necessary to resolve these flakes.
This allows to use different toolchain files for each and it reduces
build system repetition in test target setup.
The "tests-32" directories has been integrated into the "tests" one. Tests
that should only run on 32-bit are detected by their filename ending with
".32.cpp" now.
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.
The intent of these annotations was presumably to make it easier to adjust
build settings on a per-test basis, but doing this in the build system is
actually much cleaner.
This is a very basic test to check for overflow exception.
`into` instruction only exists on 32-bit, so it needs to not be built as
a 64-bit executable.
