| ;; 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 -g -emit-llvm foo.cpp -o - | opt -S -inline -sroa |
