.. _BUILD:llvm: LLVM backend ############ .. rubric:: Requirements * GCC (Gnu Compiler Collection) * GNAT (Ada compiler for GCC) * LLVM (Low-Level-Virtual Machine) and CLANG (Compiler front-end for LLVM): 3.5, 3.8, 3.9, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 11.1, 12.0, 13.0 or 14.0 .. _BUILD:llvm:GNAT: GCC/GNAT: GNU/Linux or Windows (MinGW/MSYS2) ============================================ .. HINT:: You need to install LLVM (usually depends on ``libedit``, see :ghdlsharp:`29`). Debugging is supported with LLVM 3.5 or ``>=6``. GHDL is configured by ``configure`` and built by ``make``. * First, GHDL needs to be configured. It is common to specify a ``PREFIX`` (installation directory like ``/usr/local`` or ``/opt/ghdl``). Set the proper arg, ``./configure --with-llvm-config``, to select LLVM backend. If ``llvm-config`` is not in your path, you can specify it: ``./configure --with-llvm-config=LLVM_INSTALL/bin/llvm-config``. * Next, ``make`` starts the compilation process. * Finally, ``make install`` installs GHDL into the installation directory specified by ``PREFIX``. .. rubric:: Example: .. code-block:: Bash $ cd $ mkdir build $ cd build $ ../configure --with-llvm-config --prefix=PREFIX $ make $ make install .. HINT:: If you want to have stack backtraces on errors (like assert failure or index of out bounds), you need to configure and build ``libbacktrace`` from GCC (you don't need to configure GCC). Then add the following arg to configure: ``--with-backtrace-lib=/path-to-gcc-build/libbacktrace/.libs/libbacktrace.a`` 55a77c763e2f5ffaaf9d99a05'>commitdiffstats
