From what I know (experts on CF correct me if I am wrong) clang-format is meant 
to format only some languages
(C/C++/...) and assembly is not one of them, so what is happening is that most 
of the time clang-format breaks
it, in fact we are formatting only .c and .h, but since we have some headers 
with assembly macros, I’ve seen some issues
that ranges from really ugly formatting to build break.

One thing we could do, is to export the headers that contain only assembly 
stuffs in dedicate headers (<header>_asm.h ?)
so that we could easily use a name regex to exclude "*_asm.h” from 
clang-format? And also these headers could #error if
included when __ASSEMBLY__ is not defined?

But this requires some agreement on what is the best way I guess, you can know 
better if it’s feasible or not.

Yes I’ve found that python glob, that we use to solve the wildcard, solves the 
** only for one level,
maybe we could do something better to solve that, but for now I left it as it 
is to focus on the
clang-format configuration side.
