In general, check the crt/host_config.h file to find out which versions are supported.
Sometimes it is possible to hack the requirements there to get some newer versions working, too :)

What is the Strict Aliasing Rule and Why do we care?
(OR Type Punning, Undefined Behavior and Alignment, Oh My!)
What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.
In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.
Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th
Disclaimer: I have no professional education in Compulational Fluid Dynamics, these are various notes on what I found/learned when trying to learn a bit on the topic.
Some of the notes lack sources as I wrote them up later often just remembering some StackExchange answer. Some things I might have misinterpreted.
Since version 2.23, git-blame has a feature to ignore certain commits.
This feature is useful to ignore large formatting or apparently unimportant changes.
How to use
Create a revisions list file. The file name is usually .git-blame-ignore-revs
Set the file as a default ignore file for blame by git config blame.ignoreRevsFile .git-blame-ignore-revs
