inline functions

Hi all,

I have an LLVM bitcode file, with several functions in it.
I'm trying to inline these functions as much as possible, so that I can obtain a big single function.
There is opt -inline, but it is not sufficient.

Any idea ?

There an option in opt to change the inlining threshold. Do opt --help-hidden to find it. It might help.

Thanks. It seems to work as expected now.

mark your functions with the alwaysinline attribute.

Ciao, Duncan.

const AttrListPtr attr = func->getAttributes();
const AttrListPtr attr_new = attr.addAttr(~0U, Attribute::AlwaysInline);
func->setAttributes(attr_new);
