; Test that functions with dynamic allocas get inlined in a case where
|
|
; naively inlining it would result in a miscompilation.
|
|
; Functions with dynamic allocas can only be inlined into functions that
|
|
; already have dynamic allocas.
|
|
|
|
; RUN: opt < %s -inline -S | FileCheck %s
|
|
;
|
|
; FIXME: This test is xfailed because the inline cost rewrite disabled *all*
|
|
; inlining of functions which contain a dynamic alloca. It should be re-enabled
|
|
; once that functionality is restored.

; XFAIL: *
