From: Behan Webster <beh...@converseincode.com> The LLVMLinux Project is working to be able to build the Linux kernel with clang/LLVM. With the release of LLVM 3.3 clang is now able to compile the Linux kernel with a number of small patches (available from the LLVMLinux git repo).
These patches add a macro to get the current stack pointer which allows for a single place in which to do so with ASM. Before this named registers (a gcc extension) was used to get the stack pointer. Using ASM is a more portable way of getting the stack pointer which works with both gcc and clang. This macro is of the same name used in the X86 arch.
