 1 | # avr-llvm
 2 | 
 3 | This repository has been merged into [upstream llvm](http://llvm.org/viewvc/llvm-project/llvm/trunk/lib/Target/AVR/).
 4 | Development now occurs directly in LLVM trunk, while this repository exists here solely as an archive of old work and issues.
 5 | 
 6 | At this point in time, no changes or commits are added or otherwise backported to this repository.
 7 | 
 8 | In order to compile stock LLVM will AVR support enabled, `-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=AVR` must be passed to CMake.
 9 | 
10 | ## Compiling the up-to-date backend from upstream LLVM
11 | 
12 | ```bash
13 | # Clone the LLVM repository
14 | git clone https://github.com/llvm-mirror/llvm.git
15 | 
16 | # optionally clone clang into the 'tools' folder for C/C++ compiler support
17 | git clone https://github.com/llvm-mirror/clang.git llvm/tools/clang
18 | 
19 | # where we want to place object files/executables
20 | mkdir build && cd build
21 | 
22 | # Run CMake to generate makefiles
23 | cmake ../llvm -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=AVR
24 | 
25 | # Compile everything
26 | make
27 | ```
28 | 
29 | Once this is done, you will have a number executables in `build/bin`.

31 | ## Viewing the historic avr-llvm fork
32 | 
33 | This repository contains a few years of development issues, pull requests, and branches prior to the merge of the backend into LLVM trunk.
34 | 
35 | The old development branch is named [`avr-support`](https://github.com/avr-llvm/llvm/tree/avr-support).
36 | 
37 | There is a [`master`](https://github.com/avr-llvm/llvm/tree/master) branch that points to the upstream LLVM commit that `avr-support` is based on.
