Move utility functions from dub.compilers.compiler to dub.compilers.utils.

Fix naming convention for the compiler handler classes and add documentation.

Quick fix to allow building shared libraries with LDC on Windows, with LDC on OS X, and with DMD on OS X.

fix gdc/ldc flags for ddox/docs ...

- it seems that gdc cannot currently generate a
  single json file with all output though
- remove dummy doc files after as postBuildStep

LDC 0.16.0 removed the -noboundschecks flag, replace with -boundscheck=off which is already existing in 0.15.x

Merge pull request #679 from Abscissa/fix624 ...

add buildType profile-gc ...

- allows to dub build -b profile-gc to
  trace memory allocations with dmd

Fix #624: --data=libs should output in compiler-format, not linker format.

Partially fix shared library build for LDC and skip tests for LDC/GDC. ...

Both compilers are not yet ready for shared library builds out of the box.

Use -fPIC for shared libraries compiled with LDC/GDC, too.

Change Build(Options/Requirements) to BitFlags.

Pass 'x86-64' arch to LDC instead of 'x86_64'

Fixed issue where static libraries would be generated instead of object files in singleFile build mode ...

+ Added object TargetType that is used during singleFile build mode

Use unique filenames for temporary files ...

Partial fix to #482

Fix error message with LDC

Fix output flags for compilers != dmd

Make prepareBuildSettings, extractBuildOptions and setTarget const

Removed trailing whitespace

Enable library targets for LDC compiler.

Output -l flags on the compiler command line after all source files. Fixes #281.

Merge branch 'dustmite'

Add simple support for --arch and LDC.

Add support for execution result callbacks in the build generator.

Rename BuildOptions.noBoundsChecks to noBoundsCheck to be consistent with BuildRequirements.requireBoundsCheck.

Rename some BuildOptions to avoid D keywords.

Remove dub.internal.std.process compatibility code as it doesn't support browse() and the compile status on older DMD versions isn't tracked anyway.

Fix handling of lib flags on Windows for GDC/LDC.

fix gdc/ldc build options

Move dub.utils to dub.internal.utils and update copyright dates.

Let the individual compiler classes handle passing arguments to the compiler. Fixes #86.
