| # Testing the coalescing of C++ inline functions from header files. These |
| # functions are emitted in each source file that include the header, |
| # non-inlined when -O0 is used, and coalesced into a single copy by the |
| # static linker. The static linker also tries to remove all of the debug |
| # information except one copy when it coalesces these. If that debug |
| # information defines a type that is later used by gdb, that results in |
| # <incomplete type> errors. |
| |
| # This test file specifically tests for when the linker emits the debug |
| # information for the class AFTER the debug information for the executable. |
| # The debugger is supposed to handle this correctly, and only certain |
| # linkers reorder things in this way while they're emitting the coalesced |
| # debug info stuff. |
