I have been unable to reproduce this with
6d17265fc58ec069dd1079317f14c9cdcbb60e06
(git://sourceware.org/git/binutils.git) targeting powerpc-pc-linux. I
was able to assemble

-----------------------------------------------
 	.file	"test.c"
	.text
	.globl	f
	.type	f, at function
f:                                      # @f
.Ltmp0:
	.cfi_startproc
.Ltmp1:
	.size	f, .Ltmp1-f
.Ltmp2:
	.cfi_endproc
.Leh_func_end0:
------------------------------------------------

I wonder if it was a temporary bug is gas. Could you please provide a .s
and target triple that gas rejects?
