+This directory contains LLVM bindings for the Go programming language
+(http://golang.org).
+
+Prerequisites
+-------------
+
+* Go 1.2+.
+* CMake (to build LLVM).
+
+Using the bindings
+------------------
+
+The package path "llvm.org/llvm/bindings/go/llvm" can be used to
+import the latest development version of LLVM from SVN. Paths such as
+"llvm.org/llvm.v36/bindings/go/llvm" refer to released versions of LLVM.
+
+It is recommended to use the "-d" flag with "go get" to download the
+package or a dependency, as an additional step is required to build LLVM
+(see "Building LLVM" below).
+
+Building LLVM
+-------------
+
+The script "build.sh" in this directory can be used to build LLVM and prepare
+it to be used by the bindings. If you receive an error message from "go build"
+like this:
+
+    ./analysis.go:4:84: fatal error: llvm-c/Analysis.h: No such file or directory
+     #include <llvm-c/Analysis.h> // If you are getting an error here read bindings/go/README.txt
+
+or like this:
+
+    ./llvm_dep.go:5: undefined: run_build_sh
+
+it means that LLVM needs to be built or updated by running the script.
+
+    $ $GOPATH/src/llvm.org/llvm/bindings/go/build.sh
+
+Any command line arguments supplied to the script are passed to LLVM's CMake
+build system. A good set of arguments to use during development are:
+
+    $ $GOPATH/src/llvm.org/llvm/bindings/go/build.sh -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD=host -DBUILD_SHARED_LIBS=ON
+
+Note that CMake keeps a cache of build settings so once you have built
+LLVM there is no need to pass these arguments again after updating.
+
+Alternatively, you can build LLVM yourself, but you must then set the
+CGO_CPPFLAGS, CGO_CXXFLAGS and CGO_LDFLAGS environment variables:
+
+    $ export CGO_CPPFLAGS="`/path/to/llvm-build/bin/llvm-config --cppflags`"
+    $ export CGO_CXXFLAGS=-std=c++11
+    $ export CGO_LDFLAGS="`/path/to/llvm-build/bin/llvm-config --ldflags --libs --system-libs all`"
+    $ go build -tags byollvm
+
+If you see a compilation error while compiling your code with Go 1.9.4 or later as follows,
+
+    go build llvm.org/llvm/bindings/go/llvm: invalid flag in #cgo LDFLAGS: -Wl,-headerpad_max_install_names
+
+you need to setup $CGO_LDFLAGS_ALLOW to allow a compiler to specify some linker options:
+
+    $ export CGO_LDFLAGS_ALLOW='-Wl,(-search_paths_first|-headerpad_max_install_names)'
