Ok. But in my understanding, the condition "la t9" is not enought to detect
lazy-binding.  The next case, you can't apply lazy-binding. I know
the current gcc never generates such codes.  
I think gcc should  pass information wheather the symbol is
lazy-bindable or not and gas use it.


	.set	macro
	.set	reorder

	la	t9, <sym>
	beq	t9, a1, 1f
	jal	t9
