I remember that there has been some variance throughout the versions for exactly what MSVC prints as the identification thoughout the versions, but

I was wondering if non-english locale would translate that string, but
I can't easily test that, I don't think.


Sorry, need to correct myself. It is indeed localized I was just lacking
the language pack…

For example in german it is:

Microsoft (R) C/C++-Optimierungscompiler Version 19.30.30709 für x64
Copyright (C) Microsoft Corporation. Alle Rechte vorbehalten.

Oh, thanks for that!

I presume that this also could break the other existing check for armasm too? If you run e.g. "vsdevcmd -host_arch=x64 -arch=arm64" and then "armasm64", what does that print?


Interestingly that one does not seem localized:

C:\Program Files\Microsoft Visual Studio\2022\Community>armasm64
Microsoft (R) ARM Macro Assembler Version 14.30.30709.0 for 64 bits
Copyright (C) Microsoft Corporation.  All rights reserved.

That's interesting!

I tried to have a look at what e.g. meson does for detection. It doesn't look that much at the output, but first detects clang-cl specifically, then plain clang, then moves on to MSVC itself (matching only 'Microsoft'). Meson does, however, check a longer regex for identifying and disambiguating the 'rc' tool from windres. Is 'rc' localized?
