| nptl: Fix cleanups for stack grows up [BZ# 28899] |
| |
| _STACK_GROWS_DOWN is defined to 0 when the stack grows up. The |
| code in unwind.c used `#ifdef _STACK_GROWS_DOWN' to selct the |
| stack grows down define for FRAME_LEFT. As a result, the |
| _STACK_GROWS_DOWN define was always selected and cleanups were |
| incorrectly sequenced when the stack grows up. |
| |
