Subject: [PATCH] arm: LLVMLinux: Use __builtin_frame_address to get thread info
Date: Fri, 6 Sep 2013 17:47:39 -0400 [thread overview]
Message-ID: <1378504062-9117-1-git-send-email-behanw@converseincode.com> (raw)
From: Behan Webster <behanw@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).
Use the frame pointer to calculate the start of the stack for current_thread_info()
The existing code uses the stack pointer to do this calculation.
Using the frame pointer yeilds the same value in a portable way.
This change supports being able to compile the kernel with gcc and Clang.
