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