And why not use mingw gcc? Do they find somthing wrong with it? Edit Mingw-w64 its quite nice and includes gcc without all stuff cgwin does.
It's not ABI compatible with MSVC

Apple hired developers of Clang and started supporting Clang around the time GPLv3 was being pushed by FSF, Apple at the time was using GCC in their development and feared that GPLv3 would taint their code. other than technical merits, permissible license of Clang is attractive for some developers/businesses
I thought Apple didn’t just “hire” the developers of clang. They started the clang project in-house before eventually open sourcing it.

Unfortunately, mingw profiling code and the toolchain is tainted with GPL.

#14Interesting. It seems Google is moving away from anything gpl/gnu lately (fuchsia, etc...)

Why use it? llvm is the future anyway and lots of players have a stake in it and contribute to it.
In fact, there are way too many c++ compilers if you ask me. I would gladly accept a world where clang is the one and only.

Yes; Clang was started internally to Apple. They did "just hire" the developer of LLVM.

Pretty sure this is significant in Chrome's case.
Re: Clang Is Now Used to Build Chrome for Windows
#18Have seen a couple interesting articles[0][1] highlighting the weirdness of building Chromium on Windows, so hopefully this LLVM improvement will be a step towards a smoother process.

Hey, those are mine! Those two issues (and this one: https://randomascii.wordpress.com/2018/02/11/zombie-processe...) are equally problematic with clang. Two of them were problems with Windows, and one was a flaw in a Microsoft system management component.
Luckily they are all mitigated, fixed, or being fixed, so my Chrome builds run much more smoothly now.
Re: Clang Is Now Used to Build Chrome for Windows
#19I didn't realize that clang is mostly a drop in replacement for cl, and matches the C++ abi. That in of itself is awesome.
clang isn't. clang-cl is (after years of work by the clang-cl team at Google). They had to do a lot of work, especially around PDB (symbol-file) generation.

Does this option give you full debug information? My impression was that it does not. I require full debug information for debugging and profiling, and with clang-cl I get that (context: I work on Chromium)
