commit 365f05c7a5f16aaaec06465ab6c89247c66b4574
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Fri Feb 15 13:44:17 2019 +0000

    Fix implicit-fallthrough warnings in tst-setjmp.c.
    
    Building the testsuite with -Wextra (together with
    -Wno-cast-function-type -Wno-clobbered -Wno-expansion-to-defined
    -Wno-missing-field-initializers -Wno-old-style-declaration
    -Wno-shift-negative-value -Wno-sign-compare -Wno-type-limits
    -Wno-unused-parameter, which reflect the set of -Wextra warnings for
    which glibc itself is not currently clean on x86_64) showed up
    implicit-fallthrough warnings in tst-setjmp.c.  Those warnings appear
    to be false positives, arising from a function "jump" that calls
    longjmp not itself being marked as noreturn; thus, this patch adds the
    noreturn marking to that function to fix the warnings.
    
    Tested for x86_64.
    
    	* setjmp/tst-setjmp.c (jump): Use __attribute__ ((__noreturn__)).
