I'm trying to insert a call to fprintf(stderr, ...). I've looked at the emitted assembly from llvm-gcc, and it consists of a LoadInst (of stderr) and CallInst.

Hi all, I would like to understand if there is an efficient way to identify the instruction that "created" a specific variable. For example, define i32 @main() #0 { %1 = alloca i32, align 4 %2 = alloca %struct._IO_FILE*, align 8 %3 = alloca [40 x i8], align 16 store i32 0, i32* %1, align 4 %4 = call %struct._IO_FILE* @fopen(i8* getelementptr inbounds ([51 x i8], [51 x i8]* @.str, i32 0, i32 0), i8* getelementptr inbounds ([3 x i8], [3 x i8]* @.str.1, i32 0, i32 0)) store %struct._IO_FILE* %4, %struct._IO_...

I was wondering if someone could explain why CallInst::getCalledFunc behaves the way it does. For simple, direct call instructions in my IR, that method behaves just as one would expect. However, for instructions like this: %25 = call i32 (%struct._IO_FILE*, ...)* bitcast (i32 (...)* @close to i32 > (%struct._IO_FILE*, ...)*)(%struct._IO_FILE* %24), !dbg !695 getCalledFunc returns null. I know getCalledFunc is expected to return null <http://llvm.org/docs/doxygen/html/classllvm_1_1CallInst.html#a0bcd4131e1a1d92215f5385b4e16cd2e> on indire...

Hi, I have experimentally done a branch of klibc with buffered stdio support. It seems to add about 1.5K of code (for x86-64), which isn't so bad, except that it means that *every* program now pulls in stdio, which in turn depends on malloc() and some other pieces of code. I have not yet implemented fscanf(), however, which may cause additional bloat. As of this point, I'm a bit
