2009-07-30Fix x86-64 ____longjmp_chk to handle signal stacks.Ulrich Drepper
The simple test previously used might trigger if the longjmp jumps from the signal stack to the normal stack. We now explicitly test for this case.
2009-05-21Add missing .text directives.H.J. Lu
The ____longjmp_chk functions on x86 and x86-64 were placed in .rodata.str1.1.
2009-05-15Check for valid stack frame in longjmp.Ulrich Drepper
If longjmp restores the stack frame to an address which is beyond the stack frame at the time of the longjmp call it would install an uninitialized stack frame. If compiled with _FORTIFY_SOURCE defined, longjmp will now bail out in this situation.
