[PATCH] D29044: Add LC_BUILD_VERSION load command

[Steven Wu via Phabricator via llvm-commits]

steven_wu created this revision.

Add a new load command LC_BUILD_VERSION. It is a generic version of
LC_*_VERSION_MIN load_command used on Apple platforms. Instead of having
a seperate load command for each platform, LC_BUILD_VERSION is recording
platform info as an enum. It also records SDK version, min_os, and tools
that used to build the binary.
