Subject: Fix unused function build error in lld
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5fc12bfe02d337e454278d83c7ae57bb44f81f67;p=llvm

Fix unused function build error in lld

The lld-x86_64-darwin13 is failing with:
 error: unused function 'operator<<'

Wrap the declation in ifndef NDEBUG, which matches
what is done in MipsELFObjectWriter.cpp.
