LEG Example Backend =================== This is a simple example LLVM backend for an ARM-like architecture: 'LEG'. Check out the slides from the tutorial given at Euro LLVM Developers' Conference 2014, Edinburgh: http://llvm.org/devmtg/2014-04/PDFs/Talks/Building%20an%20LLVM%20backend.pdf Look out for us at the USA LLVM Developers' Conference, October 28-29, San Jose: http://llvm.org/devmtg/2014-10/ Fraser Cormack & Pierre-André Saulais, Codeplay Software Getting Started =============== The LEG repositories (llvm-leg, clang-leg) both track tip, and aren't tied to any specific revision of LLVM/Clang. Tried & tested build systems: * CMake Tried & tested compilers: * gcc 4.9.1 * clang 3.5 Building with in-tree clang (optional) -------------------------------------- cd llvm-leg git clone git@github.com:codeplaysoftware/clang-leg.git tools/clang Building with make ------------------ cd llvm-leg mkdir build && cd build cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE:STRING=DEBUG(/RELEASE) -DLLVM_TARGETS_TO_BUILD:STRING=LEG(,X86,...) ../ make -j9 Building with ninja ------------------- cd llvm-leg mkdir build && cd build cmake -G "Ninja" -DCMAKE_BUILD_TYPE:STRING=DEBUG(/RELEASE) -DLLVM_TARGETS_TO_BUILD:STRING=LEG(,X86,...) ../ ninja Compiling some code ------------------- cd llvm-leg ### Compile IR -> Assembly ### ./build/bin/llc -march leg -o ex1.s docs/Codeplay/examples/ex1.ll cat ex1.s ### Compile IR -> ELF Object File ### ./build/bin/llc -march leg -filetype=obj -o ex1.o docs/Codeplay/examples/ex1.ll xxd ex1.o ### Compile Source -> Assembly with in-tree clang (via clang-leg) ### ./build/bin/clang -cc1 -triple leg-unknown-unknown -S -o ex1.s docs/Codeplay/example/ex1.c cat ex1.s ### Compile Source -> Assembly with in-tree clang (via clang-leg) ### ./build/bin/clang -cc1 -triple leg-unknown-unknown -o ex1.o docs/Codeplay/example/ex1.c xxd ex1.0 Low Level Virtual Machine (LLVM) ================================ This directory and its subdirectories contain source code for the Low Level Virtual Machine, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments.
