--- Comment #1 from Rui Ueyama <r...@google.com> ---
The /LTCG option is to make the linker generate code at link-time. This needs
coordination between a compiler and a linker. MSVC's cl.exe and link.exe uses
some intermediate representation of code to generate code. And that
intermediate code is highly compiler-dependent. So it is not supported by our
compiler nor linker.
We instead support LTO (link-time optimization) which is the same feature as
LTCG. Just like cl.exe and link.exe, you need to use clang-cl.exe and
lld-link.exe to use LTO.
You want to use LTO instead of LTCG.
