Revision 1.5.6.1, Fri Jul 16 18:34:08 2010 UTC (13 years, 8 months ago) by riz
Pull up following revision(s) (requested by joerg in ticket #1423): lib/libc/stdlib/exit.c: revision 1.12 lib/libc/misc/initfini.c: revision 1.6 Ensure that initfini.c is referenced by exit.c. The start up code has to reference the latter as a return of main() results in a call to exit(3), so this ensures that the libc constructors are run for statically linked programs. Fixes PR 37454. |
