;; 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.
