x86-64: Stack alignment in _dl_tlsdesc_dynamic and red zone usage (bug 31501)
|
||||
|
||||
In sysdeps/x86_64/dl-tlsdesc-dynamic.h, the stack pointer is
|
||||
realigned for some variants (notably _dl_tlsdesc_dynamic_xsavec).
|
||||
This realignment does not take into account that the function has
|
||||
already used part of the red zone at this point, thus clobbering
|
||||
the initally saved register values located there if the stack
|
||||
alignment inherited from the caller is unfortunate.
