Suppress MS-style inline assembly clang-tidy error

Hi,

I am getting the following error from clang pretty often: MS-style inline assembly is not available: Unable to find target for this triple (no targets are registered) [clang-diagnostic-error]

I know this is a problem from clang, see https://reviews.llvm.org/D17981. They don’t seem to want to fix this anytime soon… It would be pretty annoying for people to compile LLVM + Clang from scratch and apply the above patch locally just to remove this error. Would it be possible to just filter this one out?

Kind regards,

Jacob

The only way to resolve it is building llvm and clang-tidy from source and applying the patch described at https://reviews.llvm.org/D17981. The side effect is that your binaries are a bit larger (/care)

The error more specifically:

:\Program Files (x86)\Windows Kits\10\Include\10.0.15063.0\um\winnt.h(949): error: MS-style inline assembly is not available: Unable to find target for this triple (no targets are registered) [clang-diagnostic-error]
    __asm    {
    ^

This is on visual studio 2017 by the way, but i also had this on my own tooling on earlier versions. This probably requires a windows.h include.

Edit:

I found the cause, its related to passing -m32 as additional compile flag. Our code only compiles with 32bit, due to some code static_asserting we are actually compiling 32 bit.
