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.
|
||
|
|
|
||
|
|
(cherry picked from commit 2bbc694df279020a6620096d31c1e05c93966f9b)
