Use C preprocessor comments in assembly headers. We generate .S files for assembly, which means they run through the C preprocessor first. In gas targets where # is the comment marker, there is a conflict with cpp directives. The comments actually rely on #This and #source not being directives. If I begin a line with "if", the build fails. Since the C preprocessor is responsible for removing C preprocessor comments, we should be able to safely use // everywhere with less ambiguity. (In fact, we were already relying on this for 32-bit ARM. The 32-bit ARM gas line comment marker is @. 64-bit ARM uses //, and x86/x86_64/ppc64 use #.) This reportedly causes issues for goma.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
