# Go bindings to system LLVM
2+
3+
This library provides bindings to a system-installed LLVM.
4+
5+
Currently supported:
6+
7+
* LLVM 7 from [apt.llvm.org](http://apt.llvm.org/) on Debian.
8+
9+
## Usage
10+
11+
If you have a supported LLVM installation, you should be able to do a simple `go get`:
12+
13+
go get github.com/aykevl/go-llvm
14+
15+
After downloading, you may have to update the configuration for your system:
16+
17+
make config
18+
19+
If you built your own LLVM, you can also use that:
20+
21+
# update LLVM files
22+
make update SRCDIR=<dir>
23+
24+
# configure this LLVM build
25+
make config BUILDDIR=<builddir>
26+
27+
Note that you may have to comment out parts of `backports.go` if you use a
28+
newer version of LLVM.
29+
30+
## License
31+
32+
Most of the files are extracted from the LLVM source tree, specifically all
33+
\*.go, \*.cpp, and \*.h files come directly from
34+
[bindings/go/llvm](https://github.com/llvm-mirror/llvm/tree/release_70/bindings/go/llvm)
35+
in the LLVM source tree. They are all released under the [University of
36+
Illinois/NCSA Open Source License](http://releases.llvm.org/7.0.0/LICENSE.TXT)
37+
which is a permissive BSD-like license. Check upstream LLVM for detailed
38+
copyright information.
39+
40+
This README, the backports\* files, and the Makefile are separate from LLVM but
41+
are licensed under the same license.
