LDC

LDC uses the LLVM backend for code generation. LDC typically generates substantially faster binaries than DMD.

Project status

In general, LDC should work fine on most x86/x86-64 Unix-like systems, including Linux, OS X and most BSD flavors. Code generation should work for other platforms supported by the LLVM MC codegen infrastructure (for example ARM), but druntime/Phobos support will most likely be lacking.

x86-64 Windows using MSVC

• LDC/LDC2 from master branch compiles without patches.
• See Building and Hacking for detailed instructions.
• LLVM 3.1 is required (3.0 does not work because of missing TLS support); LLVM 3.2 is supported, too.
• Druntime and phobos compile but linker errors are still possible.
• exception handling still needs work (see here for a first patch; the llvm-objdump part of the patch is here and was commited in LLVM 3.3)

ARM

• Code generation is known to work.
• Some initial work has been done on druntime, but support is not yet complete – see issue #116.
