| # { dg-final { scan-symbol-section "my-test.s" {^_my_var$} {^\.data(\._my_var)?$} } } |

| # |
| # Caveats: |
| # |
| # * Only ELF and Mach-O targets are supported. Other |
| # targets, like PE/COFF, might appear to work. |
| # * For Mach-O targets, the section name matched by scan-symbol-section has one |
| # of two forms: |
| # * The Mach-O segment name followed by a comma (',') followed by the Mach-O |
| # section name. For example, "__TEXT,__text". (There is no whitespace |
| # between the Mach-O segment name and the Mach-O section name.) |
| # * ".const", ".data", or ".text". For example, the .text assembler directive |
| # causes the section name to be ".text" (not "__TEXT,__text"). (However, a |
| # directive such as .section __TEXT,__text will cause the section name to be |
| # "__TEXT,__text".) |
| # * Because scan-symbol-section parses assembly code, scan-symbol-section is |
| # unaware of section rewriting performed by the linker. For example, the |
| # sections .text._f1 and .text._f2 would normally be merged by binutils' |
| # linker into one section called .text, but scan-symbol-section reports the |
| # sections as .text._f1 and .text._f2 (and not .text). |
| # * The symbol pattern matches any assembly label, including local labels which |
| # begin with `.L`. |
