From: Behan Webster <beh...@converseincode.com> The LLVMLinux project aims to fully build the Linux kernel using both gcc and clang (the C front end for the LLVM compiler infrastructure project).
Clang only supports global named registers for non-allocatable registers like the stack pointer. By centralizing the definition of current_stack_pointer, the use of named registers for ARM remains largely unchanged while working for both gcc and clang. Behan Webster (6): arm: LLVMLinux: Add global named register current_stack_pointer for ARM arm: LLVMLinux: Use current_stack_pointer to calculate pt_regs address arm: LLVMLinux: Use current_stack_pointer for return_address arm: LLVMLinux: Use current_stack_pointer in save_stack_trace_tsk arm: LLVMLinux: Calculate current_thread_info from current_stack_pointer arm: LLVMLinux: Use current_stack_pointer in unwind_backtrace arch/arm/include/asm/ptrace.h | 5 ++--- arch/arm/include/asm/thread_info.h | 9 +++++++-- arch/arm/kernel/return_address.c | 3 +-- arch/arm/kernel/stacktrace.c | 4 +--- arch/arm/kernel/unwind.c | 3 +-- 5 files changed, 12 insertions(+), 12 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
