; FIXME: The new LTO implementation has been fixed to not internalize
|
|
; (and later dead-code-eliminate) builtin functions. However the old LTO
|

; implementation still internalizes them, and when used with ThinLTO they
|

; get dead-code eliminated before the optimizations run that insert calls
|
|
; to them (thus breaking these inserted calls). This needs to be fixed.
