llvm dev - Jul 2009 - [LLVMdev] regression: double spaced asm output for thumb-2

Something has changed in the last few days that breaks thumb-2 (and  
possibly all ARM) assembly output. Some, but not all lines are double- 
spaced, for example:

	fstd d13, [sp, #+40]

	fstd d12, [sp, #+32]

	fstd d11, [sp, #+24]

	fstd d10, [sp, #+16]

	fstd d9, [sp, #+8]

	fstd d8, [sp]

	sub sp, sp, #872

	mov r4, r1
	mov r5, r0
	cmp r0, #2

	ble LBB1_133	@ entry.bb2.i_crit_edge
LBB1_1:	@ bb.i
	ldr r0, [r4, #+8]

	bl L_atoi$stub
LBB1_2:	@ bb2.i
	str r0, [sp, #+80]

	cmp r5, #1

	ble LBB1_134	@ bb2.i.dealwithargs.exit_crit_edge
LBB1_3:	@ bb3.i
	ldr r0, [r4, #+4]

	bl L_atoi$stub
LBB1_4:	@ dealwithargs.exit
	mov r4, r0
	str r4, [sp, #+64]

	mov r0, #32
	ldr r5, [sp, #+80]

	mov r1, r5
	bl L___divsi3$stub
	str r0, [sp, #+72]

	mov r0, #64
	mov r1, r5
	bl L___divsi3$stub
	str r0, [sp, #+76]

	ldr r0, LCPI1_30

It doesn't break the assembler... but it is wrong... and ugly... and  
many other adjectives. I isolated the change and let the submitter know.
