What are the differences and tradeoffs between -march=haswell, -march=core-avx2, and -mavx2 for compiling avx2 intrinsics? I know that -mavx2 is a flag and -march=haswell/core-avx2 are architectures which just translate to a bunch of flags. So -mavx2 is a subset of the other two. But beyond that, how do I choose the right one for my application?

How does -march=native choose which instruction sets to enable and which to disable? I have the following conjecture: -march=native will be using CPUID instructions to calculate supported instruction sets etc in order to detect the processor variant -march=foobar will use a hardcoded list of instruction sets which processor foobar supports.
For -O0, whether -march=native or -march=Using -march will also allow you more possibilities to use 3rd party closed source as well. You should be able to link -mcpu=cortex-r5 with -march=armv7-r code; well it is fine in one directions, so the tools may complain.
-march: generate instructions for a specific machine type. Defaults to x86-64-v3 on AMD64 and armv8-a on AArch64. Use -march=compatibility for best compatibility, or -march=native for best performance if a native executable is deployed on the same machine or on a machine with the same CPU features. To list all available machine types, use ...

On x86 processors, just use -march=native. GCC will handle the rest by setting arch and tune to same value. ARM is trickier since GCC sometimes segfault's when using -march=native. You should also use a modern GCC or maybe Clang. Clang creates better code than GCC with some SIMD source code. You will need to benchmark to determine which performs best for your code.
Using Clang 16.0 or later, I would like to know what values could be used for the -march argument. The command clang --print-supported-cpus shows for -mcpu=, but I see no alternative for -march.
"I want change it to -march=x86-64 in cmake, How to do it? - Find out how exactly PCL adds -march=native flag. If it does that via variable CMAKE_CXX_FLAGS, then you may try to modify that variable (but note about variables scoping rules). If PCL adds the flag to some property, then you may try modify that property. CMake doesn't give you a control over combined compiler flags. You need to ...

In my opinion, have should be changed to has. Is it right? Here is what I googled related to this. "Some English speakers and writers get confused when using the pronoun phrase “each of” before a plural noun or other pronoun and incorrectly use the plural verb form (“each of them have”).
