[llvm-commits] [patch] Small fixes to the gold plugin

[Rafael Espindola]

The attached patch has two small fixes to the gold plugin. First, it
moves two checks out of the per file loop. I assume this was broken in
the recent changes. Right now the plugin will produce no output if any
file was fully unused.

The second fix is a special case for _start. We need this for the
uncommon situation that a full program is LLVM IL (including the crt*
files). In this case the resolution of nothing is LDPR_PREVAILING_DEF
and we drop all symbols.

Cheers,
