This redoes the default mode that ccc runs in w.r.t. using clang. Now
ccc defaults to always using clang for any task clang can
handle. However, the following options exist to tweak this behavior:
-ccc-no-clang: Don't use clang at all for compilation (still used for
static analysis).
-ccc-no-clang-cxx: Don't use clang for C++ and Objective-C++ inputs.
-ccc-no-clang-cpp: Don't use clang as a preprocessor.
-ccc-clang-archs <archs>: If present, only use clang for the given
comma separated list of architectures. This only works on Darwin for
now.
Note that all -ccc options must be first on the command line.

- Toolchain is responsible for providing list of prefixes to search.
- Implement -print-file-name=xxx and -print-prog-name=xxx driver options.
llvm-svn: 62659
- For now forces generation of plist files, need to think about the
right interface.
- Changed -fsyntax-only mode to be its own phase (more consistent).
- Add -WA, for passing options verbatim to analyzer.

- This is a hack to allow the Darwin linker to get -final_output when
doing universal builds; the mechanism should be generalized.
- Handle multiple redundant -arch arguments correctly.
- Forward -arch_multiple and -final_output to gcc when necessary.
- Simplified implementation of derived gcc tools.
llvm-svn: 62618
- Add Darwin_X86_CC1Tool which is shared by Darwin/x86/Compile and
Darwin/x86/Preprocess tools.
- Minor bug fixes (CmpDriver exit code, -x cpp-output handling, some
linker argument translation).
llvm-svn: 62551
for the Darwin tool chain.
- Ideally we would localize these to tool specific argument
processing but for now this matches gcc closely.
llvm-svn: 62181
- Pulled -Xarch processing into this.
- Get rid of manual creation of forwarding arg array.
- Use Darwin/CC1 instead of generic GCC cc1 on X86.
llvm-svn: 62172
- --gstabs only goes to Darwin/Assembler when dealing with an
assembly file from the command line.
- Relative placement of -o option for cc1 moves depending on
-fsyntax-only/-S, how quaint.
llvm-svn: 62152
- Support comma joined options which magically turn into multiple
value arguments (e.g., -Wl,)
- Split out separate Arg::render routine for when an argument is
being rendered as an input (as opposed to in its original form).
- Add option flag for options which should be rendered without the
option when they are used as an input (e.g., -Xlinker or -o).
- Support -weak-l..., -weak_framework, and -weak_library.

perform them.
- A ToolChain is a coherent set of tools use in a compilation
process. The idea is that a ToolChain holds roughly the information
(specs, search paths, etc.) that is in a single gcc binary.
- The default ToolChain is selected by the host and will generally
correspond to what the default system compiler would do. However,
this can be over-riden for a variety of purposes, for example the
by the driver driver or for testing.
llvm-svn: 62021
- For use by the driver in places where the host alters driver
behavior (for example, running as a driver driver on darwin).
- Allow user override for testing purposes.
llvm-svn: 61967
"fake" options, allowing Tools to be oblivious to whether an argument
is real or synthetic. This kills off DerivedArg & a number of FIXMEs.
llvm-svn: 61871
- Entry point is tools/ccc/xcc until we are a functional replacement
for ccc.
This is highly experimental (FIXME/LOC ratio of 3.4%), quite crufty,
and barely usable (and then only on my specific Darwin). However, many
of the right ideas are present, and it already fixes a number of
things gcc gets wrong.
The major missing component is argument translation for tools
(translating driver arguments into cc1/ld/as/etc. arguments). This is
a large part of the driver functionality and will probably double the
LOC, but my hope is that the current architecture is relatively
stable.
Documentation & motivation to follow soon...
