[LLVMdev] Inlining

[Duncan Sands]

Hi Alastair,

This is typically used to implement inline functions, templates, or other code which must be generated in each translation unit that uses it. Unreferenced linkonce globals are allowed to be discarded.

I was wrong - linkonce is an exception to the general rule that a "weak" linkage
type prevents inlining unless of the "_odr" form.

Ciao,

Duncan.
