* linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart
|
||||
and pthread_handle_sigcancel with functions that restore
|
||||
%gs from the signal context. For each signal handling function,
|
||||
two wrappers are required, one for a non-RT signal and one for
|
||||
a RT signal.
|

* linuxthreads/signal.c: For i386, add code to restore %gs

||||
from the signal context in pthread_sighandler and

pthread_sighandler_rt.
