;; This test checks the following:
;; 2. Function static variable, typedef, records (structure, class and union)
;; that are defined in lexical function scope are emitted as children to
;; the function scope, directly.
;; 3. "bar" function, which was inlined into "foo" function, is created as
;; abstract (with DW_AT_inline attribute).
;; All variables and types are defined in this abstract entry.
;; 4. "bar" function is created in "foo" function as inlined function
;; (with DW_TAG_inlined_subroutine attribute), and all its local variables
;; are created as concrete variables pointing to the abstract suitable entry
;; defined under abstract "bar" function.
;;
;; This test was generated by running following command:
;; clang -cc1 -O0 -debug-info-kind=limited -emit-llvm foo.cpp -o - | opt -S -inline -sroa
;; Where foo.cpp
