# With bootstrap enabled (the default), gdc is used (through the gdmd wrapper)
# to build ldc (and shared runtime), then the built ldc is used to build ldc
# itself again. The final ldc with shared runtime is then installed.
# With bootstrap disabled, ldc from the ldc package is used directly to build
# the new ldc. Note that the resulting ldc is linked against the old ldc's
# runtime, which might not be compatible with the newly built one!

%description
LDC is an LLVM based compiler for the D programming language. It uses the
frontend of the reference compiler (DMD), thereby supporting the same language
features, but profits from LLVM's superior optimizing and code generation
capabilities.
