A relatively simple piece of code:
// RUN: clang -emit-llvm %s
int g(int);
int foo(int i) {
return g(i);
}
int g(int i) {
return i;
}
Is compiled incorrectly to:
; ModuleID = 'foo'
target triple = "i686-apple-darwin9"
define i32 @foo(i32 %i) {
entry:
...
%call = call i32 @g( i32 %tmp ) ; <i32> [#uses=1]
ret i32 %call
}
declare i32 @g(i32)
define i32 @g1(i32 %i) {
entry:
...
}
This only occurs if the prototyped function (in this case 'g') is
called before it is actually defined.
