...it's unused, but that's not applicable in this case. Any particular reason the inliner doesn't touch varargs? I think that when you call a varargs function without any varargs, it should be able to inline it just fine? Or at least when the function in question also doesn't call the va_* functions. > > Also, shouldn't the function g() get inlined in the h() function?

The va_start probably is unnecessary now in bar, but where dus the va_end need to be: at the end of foo or...

There is an implicit dependency between vastart and the function it lives in. Specifically, if you have: void foo(int X, ...) { P = va_start(); use(P); } You can't change this to: void foo(int X, ...) {...

I've been rethinking my use of lib/Transforms/Utils/ CodeExtractor::ExtractCodeRegion(...) to obtain my first goal, but I don't think I need such a complex algorithm after a...

Hi, I have two questions about optimizations performed by llvm. Consider these simple functions: int x(int b) { return b?4:6; } int y() { return x(0); } int x2() { return 5; } int y2() { return x2(); } the optimized bitcode (with clang + opt -std-compiler-opts) is: define i32 @y(...) nounwind { entry: ret i32 6 } define i32 @y2(...) nounwind { entry: %call = call i32 (...)* @x2( ) ;
