Revision 1.6, Wed Sep 26 00:09:48 2012 UTC (11 years, 7 months ago) by brad
Branch: MAIN
CVS Tags: OPENBSD_5_9_BASE, OPENBSD_5_9, OPENBSD_5_8_BASE, OPENBSD_5_8, OPENBSD_5_7_BASE, OPENBSD_5_7, OPENBSD_5_6_BASE, OPENBSD_5_6, OPENBSD_5_5_BASE, OPENBSD_5_5, OPENBSD_5_4_BASE, OPENBSD_5_4, OPENBSD_5_3_BASE, OPENBSD_5_3 Changes since 1.5: +7 -7 lines
Explicitly annotate setjmp() and longjmp() (and friends) as
__returns_twice and __dead instead of depending on GCC's special
handling of these function names.
With input from kettenis@ and guenther@
Fixes a warning from clang
