* sysdeps/ia64/elf/initfini.c [HAVE_INITFINI_ARRAY]

(gmon_initializer): New function.
	(.init prologue): If HAVE_INITFINI_ARRAY is true, don't call
	__gmon_start__ here.  Call it from gmon_initializer() instead.

2002-03-12  H.J. Lu  <hjl@gnu.org>

	* elf/Makefile [$(have-initfini-array) = yes] (tests): Add tst-array1,
	tst-array2, and tst-array3.
	[$(have-initfini-array) = yes] (tests-static): Add tst-array3.
	[$(have-initfini-array) = yes] (modules-names): Add tst-array2dep.
	($(objpfx)tst-array1.out): New target.
	($(objpfx)tst-array2): Likewise.
	($(objpfx)tst-array2.out): Likewise.
