Ulrich Drepper	421665c40a	Optimize x86-64 syscall cancellation handling. The syscall wrappers had to save and restore the syscall parameter values and return value when calling the functions to enable/disable cancellation were called. Not anymore. The called functions are special and don't modify any unexpected registers.	2009-08-04 11:03:46 -07:00

Optimize x86-64 syscall cancellation handling.

The syscall wrappers had to save and restore the syscall parameter
values and return value when calling the functions to enable/disable
cancellation were called.  Not anymore.  The called functions are
special and don't modify any unexpected registers.
