[PATCH] D133092: [clang] fix generation of .debug_aranges with LTO

[Kazushi Marukawa via Phabricator via cfe-commits]

kaz7 added a comment.

For your information, after this patch `check-clang` fails with following errors if there is no lld is installed (lld is not enable in CMake, and lld is not installed previously).  I appreciate if you run debug-options.c test with `-fuse-ld=lld` if the lld is existing.  Thanks.
