; ToT gold (as of 03/2016) honors --start-lib/--end-lib, drops %t2.o and ends up
; with (i32 align 4) symbol.
; Older gold does not drop %t2.o and ends up with (i32 align 8) symbol. This is
; incorrect behavior, but this test does not verify this in order to support
; both old and new gold.

; Check that the common symbol is not dropped completely, which was a regression
; in r262676.
