 If LLVM strives to be GNU toolchain compatible, then this looks like a 
bug in their scanner as generic ELF support in GAS (gas/config/obj-elf.c) 
has this, in `obj_elf_type':

  if (*input_line_pointer == ',')
    ++input_line_pointer;

so the comma is entirely optional.  I realise this is undocumented, but 
there you go.  It must have been there since forever.

It contradicts documentation.  The gas manual says:

* Type::                        `.type <INT | NAME , TYPE DESCRIPTION>'

And the SGI assembler manual I dug up as ".type name, value".  So maybe
gas is too generous here?

 I find it interesting that you mention SGI here as the commit which might 
be responsible for the current interpretation is this:

Mon Sep 12 17:51:39 1994  Ian Lance Taylor  (ian@sanguine.cygnus.com)

	* config/obj-elf.c (obj_elf_type): Rewrite to accept syntax
	reportedly to be used on Irix 6.

Given its age I doubt further information can be found, it might be just 
sloppy coding.

Either way, I think the patch is right and I've just applied v2.

 Sure, thanks!
