Hello, Whenever I compile a C program containing "FD_SET" function using llvm-gcc 2.7 (with -emit-llvm option), I got the following inline assembly in my llvm byte code: %asmtmp = call %struct.__mbstate_t asm sideeffect "cld; rep; stosl", "={cx},={di},{ax},0,1,~{dirflag},~{fpsr},~{flags},~{memory}"(i32 0, i32 32, i32* getelementptr inbounds (%struct.__sigset_t*

I have a new problem: Register RBP is used in a function foo. (I am not allocating RBP to any virtual register, the instances of RBP in function foo are in the machine code when my register allocator starts.) Function foo calls function bar. Register RBP is not saved across the call, though it is live after the call. Function bar includes a virtual register. The code that I'm using to
