Just to make it clear, I'm not an official representative of Clang, or
LLVM, nor I was involved in all discussions about implementing
extensions either. I do not have an agenda to promote LLVM changes.
However, I am trying to promote change to both code bases such that the
Linux kernel can be compiled with both gcc and clang. Indeed both myself
and others in the project send patches upstream to both code bases.
__builtin_stack_pointer is an idea from a couple of us on the LLVMLinux
project. Renato is merely helping us out connecting us to the right
people to talk to.
Actually the proposal was more about making it easier to solve this
particular problem in a way which might be acceptable to all parties.
To me this sounds like clang proposing extensions because they aren't
willing to implement existing extensions, not a good reason to change.
I'm open to all suggestions.
