.gitignore: ignore external debug symbols from GCC on macOS

szeder · gitster · commit ff0eec9e540e · 2019-01-17T11:14:45.000-08:00
When Git is build with a "real" GCC on macOS [1], or at least with GCC installed via Homebrew, and CFLAGS includes the '-g' option (and our default CFLAGS does), then by default GCC writes the debug symbols into external files under '<binary>.dSYM/' directories (e.g. 'git-daemon.dSYM/', 'git.dSYM/', etc.). Update '.gitignore' to ignore these directories, so they don't clutter the output of 'git status'. Furthermore, these build artifacts then won't trigger build failures on Travis CI via b92cb86 (travis-ci: check that all build artifacts are .gitignore-d, 2017-12-31) once one of the following patches updates our CI build scripts to use a real GCC in the 'osx-gcc' build job. [1] On macOS the default '/usr/bin/gcc' executable is not a real GCC, but merely a compatibility wrapper around Clang: $ gcc --version Configured with: --prefix=<...> Apple LLVM version 9.0.0 (clang-900.0.39.2) <...> So even though 'make CC=gcc' does indeed execute a command called 'gcc', in the end Git will be built with Clang all the same.
