FLiT v2.1.0

FLiT is now very stable, so we can exit the beta releases. Honestly, we kept it in the beta release not because the tool was unreliable, but rather because we were unsure if the interface would undergo breaking changes with design reworks.

The interface has stabilized. We may do small breaks of interface in the future, but so far nothing major until FLiT 3.0.

Highlights of Major Changes:

• Place items from flit::fsutil namespace into the flit namespace (breaking change)
• MPI
  • Add MPICH support
  • Change MPI usage to be with a main-like function as subprocesses
• flit bisect
  • Bisect uses information from flit-config.toml if the given compiler matches one specified there.
  • Improve speed of the generated Makefile
  • Add --compiler-type flag
  • Add --ldflags, --add-ldflags, and --use-linker
• Autogenerated Makefile
  • Use standard GNU Makefile variable names
  • Brief colored output
  • Source files can have any suffix (instead of just .cpp)
  • Removed the automatic insertion of --gcc-toolchain and --gxx-name for the Clang and Intel compilers respectively -- user can now add this from flit-config.toml (documentation added on how to do this)
  • Experimental support for a Ninja build file instead (through flit experimental ninja)
  • Improve speed and responsiveness using more self-recursion
  • Faster make clean by deleting output directories rather than all files
  • Mitigate C++ standard library incompatibility by compiling FLiT source code into each test executable
• flit-config.toml
  • Add fixed_compile_flags and fixed_link_flags fields for each compiler specified in flit-config.toml
• Return std::vector of float, double, long double, or std::string from tests. Add a comparison function for each.
• Add functions to FLiT's C++ interface (can be used in tests): rsplit(), lsplit(), split(), trim(), rstrip(), lstrip(), strip(), basename(), and dirname()
• Bash-completion
