WRF v4.0.x Compatibility with Compilers

I am here today to ask if there is any resources that could answer the following question:

Is the WRF version 4.0 compatible with either the PGI version 20 compiler or the Intel version 20 compiler? I understand that WRF version 4.0 was made in 2018 and the compilers previously mentioned were released recently (PGI version 20 was released 2020).
 
I can answer about the intel ones.

There are two types of intel compilers now (Intel Classic Compiler and Intel LLVM compiler). With Intel changing and archiving the Classic Compilers (ifort/icc/icpc) which are now a paid feature through intel, the llvm compilers are the free compilers available on their website. The Intel llvm compilers were added to the configure option with v4.6.0.

If you have the older classic compilers for intel, ie. prior to 2024, then they are the intel compilers listed on the configure folder.

As for pgi I haven't played with them yet so I cannot speak to them.
