Daniel Dunbar 5a9d1835be Driver: Fix PR4062 by dissecting one particular -Wp, form. 
llvm-svn: 105966
 2010-06-14 21:37:09 +00:00
Daniel Dunbar fb3d747fc6 Driver: Dissect -Wl, and -Xlinker arguments to remove --no-demangle, which was a 
collect2 option that is passed by some projects (notably WebKit).

llvm-svn: 105964
 2010-06-14 21:23:12 +00:00
Daniel Dunbar af8decbde0 Driver: Switch Compilation to return the translated arguments by default. 
llvm-svn: 105844
 2010-06-11 22:43:38 +00:00
Daniel Dunbar 775d406043 Driver: Add an explicit argument translation phase to the driver itself. We are going to need this to handle things like -Xassembler, -Xpreprocessor, and -Xlinker which we might have to introspect. 
llvm-svn: 105842
 2010-06-11 22:00:26 +00:00
Daniel Dunbar 18974bdc68 Fix a couple comments. 
llvm-svn: 105840
 2010-06-11 22:00:19 +00:00
Daniel Dunbar 35cbfeba8f Driver: Eliminate Arg subclasses, which are now unnecessary. 
llvm-svn: 105762
 2010-06-09 22:31:08 +00:00
Daniel Dunbar 24e52992c0 Driver: Support invoking Clang on .ll or .bc inputs. 
- We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o').

It is now possible to do something like:
  $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ...
  $ clang -c t.ll -o t.o ... assorted other compile flags ...
and expect that the output will be almost* identical to:
  $ clang -c t.c -o t.o ... assorted other compile flags ...
because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend.

*: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally.

Daniel Dunbar 6beaf5110f Driver/Darwin: Model dsymutil properly, as a separate action/tool kind which is 
added as the last output step, instead of just hacking it into the link step.
 - Among other things, this fixes dSYM generation when using multiple -arch options.

llvm-svn: 105475
 2010-06-04 18:28:41 +00:00
Daniel Dunbar 07494795e5 Driver: When printing a "command was signalled" type of diagnostic, use the 
short name of the tool in use, instead of the name of the action that created
the command. The practical impact is we now get:
  clang: error: clang frontend command failed due to signal 6 (use -v to see invocation)
instead of:
  clang: error: assembler command failed due to signal 6 (use -v to see invocation)
when clang crashes on a job that uses the integrated assembler.

llvm-svn: 104417
 2010-05-22 00:37:20 +00:00
Daniel Dunbar f9ff35010c Driver: Enable -integrated-as by default, at least for Darwin/x86 without -static. 
- How else will we figure out what is broken, eh?

llvm-svn: 103759
 2010-05-14 02:03:00 +00:00
Chris Lattner 86ed5b016a add a new --print-diagnostic-categories option, which causes the driver to 
print out all of the category numbers with their description.  This is useful
for clients that want to map the numbers produced by 
--fdiagnostics-show-category=id to their human readable string form.  The
output is simple but utilitarian:

$ clang --print-diagnostic-categories
1,Format String
2,Something Else

This implements rdar://7928193

llvm-svn: 103080
 2010-05-05 05:53:24 +00:00
Daniel Dunbar 3d45e17d15 Driver: Add a Tool::hasGoodDiagnostics hook, and use it to simplify logic for 
deciding when we need to emit an extra "command failed" diagnostic.
 - This also fixes the case where we were emitting that extra diagnostics, even
   when using clang w/ the integrated assembler, which has good diagnostics.

llvm-svn: 100529
 2010-04-06 17:07:49 +00:00
Daniel Dunbar e43887bd2b Driver: Add support for a CLANGXX_IS_PRODUCTION build variable, which enable 
Clang++ support, even in "Production" mode (for testing purposes).

llvm-svn: 100119
 2010-04-01 18:21:41 +00:00
Chandler Carruth 8455924303 Add very limited support for GCC's '-B' flag. This allows us to support unusual 
toolchain configurations and is a small step toward FreeBSD support.

llvm-svn: 99159
 2010-03-22 01:52:07 +00:00
Daniel Dunbar 6a8efa8a79 Driver: Support CC_PRINT_OPTIONS, used for logging the compile commands (in -v style) to a file. 
llvm-svn: 99054
 2010-03-20 08:01:59 +00:00
Daniel Dunbar 66187b3c6e Driver: Free Action objects.

Chris Lattner 09797543bd add TCE target support, patch by Pekka J! 
llvm-svn: 97746
 2010-03-04 21:07:38 +00:00
Daniel Dunbar 3babf5df64 Driver: Allow driver title (for --help) to be overridden by clients. 
llvm-svn: 97106
 2010-02-25 03:31:53 +00:00
Daniel Dunbar 0ac9445098 PR5803: clang++: Treat untyped 'C' inputs as C++. 
- Patch by Andrzej K. Haczewski, with a tweak by me to emit a 'deprecated'
   diagnostic when we do this. We'll see what zee users say.

llvm-svn: 96511
 2010-02-17 20:32:58 +00:00
Daniel Dunbar aeea8ac3d8 Driver: Add -rewrite-objc, which is an interface to clang -cc1 -rewrite-objc. 
llvm-svn: 95849
 2010-02-11 03:16:21 +00:00
Daniel Dunbar 84f22f9da1 Driver: Fix infinite loop and wrong message on invalid -ccc-clang-arch argument. 
llvm-svn: 95848
 2010-02-11 03:16:07 +00:00
Daniel Dunbar c434394d18 Driver: Add -[no-]integrated-as for clang. 
- Requires backend support, which only exists for i386--darwin currently.

No 'as' required:
--
ddunbar@ozzy:tmp$ cat t.c
int main() { return 42; }
ddunbar@ozzy:tmp$ clang -m32 -integrated-as t.c


ddunbar@ozzy:tmp$ ./a.out; echo $?
42
ddunbar@ozzy:tmp$
--

The random extra whitespace is how you know its working! :)

llvm-svn: 95194
 2010-02-03 03:07:56 +00:00
Daniel Dunbar fcf2d428e4 ASTUnit: Don't check that input files exist when parsing ASTs from the command 
line -- they may be remapped (fake) files. This is useful for testing parsing
entirely from memory.

llvm-svn: 94395
 2010-01-25 00:44:02 +00:00
Ted Kremenek 4c0df3dc1d Rename getClangFullVendorVersion() to getClangFullVersion(). 
llvm-svn: 94273
 2010-01-23 02:11:34 +00:00
Ted Kremenek 51b8bc93f8 Move version string generation (e.g., "clang 1.1 ...") to libBasic/Version.cpp, getClangFullVendorVersion(). 
llvm-svn: 94235
 2010-01-22 22:29:50 +00:00
Ted Kremenek 18e066f6a9 (1) Rename getClangSubversionRevision() to getClangRevision(), and 
have it return a StringRef instead of an integer (to be more VCS
    agnostic).

(2) Add getClangFullRepositoryVersion(), which contains an
    amalgamation of the repository name and the revision.

(3) Change PCH to only emit the string returned by
    getClangFullRepositoryVersion() instead of also emitting the value
    of getClangSubversionRevision() (which has been removed).  This is
    functionally equivalent.

More cleanup to version string generation pending...

llvm-svn: 94231
 2010-01-22 22:12:47 +00:00
Ted Kremenek 2377a0e0ea Rename getClangSubversionPath() -> getClangRepositoryPath() and have it return a StringRef. 
llvm-svn: 94213

 2009-12-23 00:47:42 +00:00
Daniel Dunbar c7a67b7877 Driver: When linking, don't warn about unused arguments which are obviously only 
used during compilation.
 - There is no easy way to define this group properly, unfortunately, and maybe
   this is a losing strategy. For now this is unambiguous more friendly, though.

llvm-svn: 91940

 2009-12-05 00:13:59 +00:00
Daniel Dunbar acd6957b59 Driver: Switch -ccc-* options to using the standard options functionality.

Daniel Dunbar da13faf982 Driver: ArgList doesn't depend on Options.h anymore. 
llvm-svn: 89313
 2009-11-19 04:25:22 +00:00
Daniel Dunbar fffd18167d Driver: Switch to using explicit {getLast,has}ArgNoClaim functions instead of taking a Claim argument. 
- Most driver code always claims, and bool arguments don't play nice with the overloads.

llvm-svn: 89308
 2009-11-19 04:00:53 +00:00
Daniel Dunbar 0bfb21e4b0 Use Option::matches instead of direct ID comparison.

 2009-10-09 17:31:54 +00:00
Douglas Gregor 1b7035da6f Provide a common set of routines in Version.h that return Subversion 
branch/revision information. Use that information in the driver,
rather than one-off branch/revision computation. 

llvm-svn: 83321
 2009-10-05 20:33:49 +00:00
Daniel Dunbar 5564ba743f Push "clang-is-production" logic up to tools/driver, and make it hittable by

 2009-09-22 22:31:13 +00:00
Daniel Dunbar 07806ca7ab Improve driver error message when only running the preprocessor and an input is 
already preprocessed.

llvm-svn: 80678
 2009-09-01 16:57:46 +00:00
Daniel Dunbar 516bb9dd76 Remove arch normalization from Driver, this should be unnecessary now that

llvm-svn: 79861
 2009-08-23 19:41:53 +00:00
Daniel Dunbar b5bcd6b94a Temporarily switch clang back to not using clang-cc by default for C++, and only 
using clang-cc on i386 and x86_64.

llvm-svn: 79859
 2009-08-23 18:42:54 +00:00
Edward O'Callaghan 856e4ff78d Second half of, clang, AuroraUX toolchain support. 
llvm-svn: 79713
 2009-08-22 01:06:46 +00:00
Daniel Dunbar 07b749230c Switch the driver back to always using clang-cc by default (for C++, and 
regardless of the architecture).
 - This is a good default for development & testing; for example without this
   any tests using 'clang' in the test suite will fail on PowerPC, since the
   driver will avoid using clang.

 - We don't want to actually ship something built this way, but that should be
   handled via some sort of configuration file.

llvm-svn: 76886

Daniel Dunbar 38bfda6ab5 Driver: Move Compilation::Execute to Driver::ExecuteCompilation. 
- The Compilation is just a helper class, it shouldn't have that amount of
   logic in it.

 - No functionality change.

 2009-06-16 23:25:22 +00:00
Eli Friedman 5cd659fd32 Fix for PR4140: Add the start of a Linux toolchain (basically, just 
barely enough to get the given usage of -print-file-name working).

llvm-svn: 72412
 2009-05-26 07:52:18 +00:00
Daniel Dunbar 51c7f97bea (llvm up) Use llvm::Triple for storing target triples. 
- This commit has some messy stuff in it to extend string lifetimes, but that

 2009-05-18 21:47:54 +00:00
Daniel Dunbar 5e051f9a86 Add --analyze-auto. 
- Currently just an alias for --analyze, eventually we want to refit
   --analyze so that it is less automatic (i.e., does not force plist
   output and does not hard code the list of checks).

Daniel Dunbar dac54a81df Driver: Prep for tool chain specific argument translation. 
- Lift ArgList to a base class for InputArgList and DerivedArgList.
 
 - This is not a great decomposition, but it does embed the
   translation into the type system, and keep things efficient for
   tool chains that don't want to do any translation.

 - No intended functionality change.

Eventually I hope to get rid of tool chain specific translation and
have each tool do the right thing, but for now this is the easiest way
to match gcc precisely (which is good for testing).

Daniel Dunbar 88f356e16b Driver: Change default use of "clang" compiler. 
- Don't default to using clang for C++ (use -ccc-clang-cxx to
   override).

 - Default to only using clang on i386 and x86_64 (use
   -ccc-clang-archs "" to override).

 - <rdar://problem/6712350> [driver] clang should not be used on
   powerpc by default
 - <rdar://problem/6705767> driver should default to -ccc-no-clang-cxx

I plan to add a warning that we are not using the clang compiler for
the given compilation so that users do not think clang is being used
in situations it isn't.

This change is motivated by the desire to be able to drop clang into a
build and have things "just work", even if it happens to get used to
compile C++ code or code for an architecture we don't support yet.

 - The later is unfortunate, as it prevents us from generally warning

   toolchain. However, we can't do much better without significantly
   complicating things, and generally we should have proper tool chain
   definitions.
