commit eb9f4715e9826cbe89be0778e43ed144bcd1d5bc
Author: Peter Avalos <pavalos@dragonflybsd.org>
Date:   Sun Apr 26 03:57:31 2009 +0000

    Update some of the amd64 parts of libc:
    
    * Change the syscall stub branch orders so that the static branch
    prediction will assume that syscalls will succeed rather than fail.
    
    * Add error handling for PSEUDO syscalls.
    
    * Add END() macros for Assembler code. This causes the symbol
    table to include the size of the function.
    
    * ldexp:  Fix a typo in the !__GNUC__ case and remove an obsolete
    comment.
    
    * setjmp/longjmp changes:
    -Save and restore the control part of the MXCSR in addition to the
    i387 control word to ensure that the two are consistent.
    -Don't clobber the FPU exception flags in longjmp. C99 requires them
    to remain unchanged.
