After finishing the frontend -I'm planning to rewrite the compiler in Elna itself with its own backend and -a hand-written parser. So GCC gives a way to have a simple bootstrap compiler -and a possbility to compile Elna programs for different platforms. - -## Grammar - -Flex and bison grammar specifications, `lexer.ll` and `parser.yy`, can be found -in the `boot/` directory. - -## Build - -The frontend requires GCC 15.2.0 (not tested with other versions). - -Download the GCC source. Copy the contents of this repository into `gcc/elna` -inside GCC. Finally build GCC enabling the frontend with -`--enable-languages=c,c++,elna`. After the installation the compiler can be -invoked with `$prefix/bin/gelna`. - -There is also a `Rakefile` that downloads, builds and installs GCC into the -`./build/` subdirectory. The `Rakefile` assumes that ruby and rake, as well as -all GCC dependencies are already available in the system. It works under Linux -and Mac OS. In the latter case GCC is patched with the patches used by Homebrew -(official GCC doesn't support Apple silicon targets). Invoke with - -```sh -rake boot -``` - -`gcc` binary is used by default, but a different gcc version can be specified -by passing `CC` and `CXX` environment variables to rake, e.g.: - -```sh -rake CC=gcc-15 CXX=g++-15 boot -``` - -See `rake -T` for more tasks. The GCC source is under `build/tools`. The -installation path is `build/host/install`. |
