Detailed Description
DragonEgg is a GCC plugin that replaces GCC's optimizers and code generators with those from the LLVM project. It can target the x86-32/x86-64 and ARM processor families. It fully supports C, C++ and Fortran. It has partial support for Ada, Go, Java, Obj-C and Obj-C++.
Benefit to Fedora
Inclusion of DragonEgg in Fedora Linux provides software developers with more optimization and code generation options for use of the GCC compilers with most of languages supported by GCC. DragonEgg also allows GCC to be used for cross-compilation to target architectures supported by LLVM without requiring any special cross-compilation compiler packages.
Scope
Each DragonEgg release is dependent on the corresponding release of LLVM, and also supports specific releases of GCC. The package maintainer will have to track these releases. The DragonEgg feature does not affect other parts of the distribution.
How To Test
- No special hardware/data/etc. is needed.
- There should not be any special preparation needed beyond installation of the dragonegg package.
- Compile a few C (or Fortran, etc.) programs using GCC with dragonegg. This is done by invoking GCC in the normal way, but with the addition of a "-fplugin=dragonegg" command line argument.
- Programs compiled using GCC with dragonegg should produce the same results as those compiled with normal GCC, though the performance may vary since different optimizers and code generators are used.
User Experience
- This package is only applicable to developers, and will not directly affect user experience.
Dependencies
- No other packages presently depend on this feature.
Contingency Plan
- None necessary. DragonEgg can be omitted if there are problems.
Documentation
Release Notes
- DragonEgg is a plugin for the GCC compilers to allow use of the LLVM optimization and code generation framework. DragonEgg provides software developers with more optimization and code generation options for use with the GCC compilers. DragonEgg also allows GCC to be used for cross-compilation to target architectures supported by LLVM without requiring any special cross-compilation compiler packages.
