How to force an unused function declaration in clang
...any other way to force the declaration of
"unused" function declarations with clang.
I have hacked in clang 6.0.0 in tools/clang/lib/CodeGen/CodeGenModule.cpp
file. I changed in EmitGlobal function to detect if the function has "used"
attribute and then if it has then use "GetOrCreateLLVMFunction" this to
create the function declaration. However, this hack fails in some other
cases. Therefore I am looking for a proper way to do this.

[LLVMdev] inefficiencies in ConstantUniqueMap ?

I now get:
%struct.T = type { i8* }
@t = global %struct.T { i8* bitcast (void ()* @f to i8*) }, align 8
declare void @f()
(I lowered the incomplete function type all the way to void, instead
of to void(), only because that made it simpler for
CodeGenModule::GetOrCreateLLVMFunction() to tell the difference
between a proper function type and a placeholder type. There's
probably a better way of doing this.)

This makes perfect sense to me.

[LLVMdev] Performance regression on ARM
Hi Chandler,
That's embarrassing how weird this part of clang is. I have a provisional
patch which fixes the problem but underlines clang's problems. I will
submit it tonight for comments.
