We've been lax about matching END() macros in asm code for some time. This is used to set the ELF size attribute for functions. It isn't normally critical but some things can make use of it (gdb for stack traces). Valgrind needs it so I'm adding it in. The problem is present on all branches and on both i386 and amd64. 2008-11-01 21:10:54 -04:00			`END(ldiv)`
