This is a short outline of how to install the C++ workload with Visual Studio or the build tools using winget.

To find VS releases with winget use search. winget search buildtools

The install command will install the VS installer with the core of the selected product installed. That isn't much. So if you use either of these commands to insll VS or the build tools you will need to launch the VS installer afterwards and select the relevant C++ workloads you need.

winget install Microsoft.VisualStudio.2022.BuildTools

winget install Microsoft.VisualStudio.2022.Community

open Terminal, go to the dir : cd /Applications/Beyond Compare.app/Contents/MacOS
change the name BCompare to BCompare.bak: mv BCompare BCompare.bak
touch a file name BCompare , and chmod a+ux BCompare : touch BCompare && chmod a+ux BCompare
open BCompare with text editor, insert the script :

#!/bin/bash
rm "/Users/$(whoami)/Library/Application Support/Beyond Compare/registry.dat"
"`dirname "$0"`"/BCompare.bak $@

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
