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.

Blaine Garst fc83aa04db Unconditionally support block introspection data in a new field at the end
of the block descriptor field.  This field is the ObjC style @encode
signature of the implementation function, and was to this point
conditionally provided in the block literal data structure.  That
provisional support is removed.

Additionally, eliminate unused enumerations for the block literal flags field.
The first shipping ABI unconditionally set (1<<29) but this bit is unused
by the runtime, so the second ABI will unconditionally have (1<<30) set so
that the runtime can in fact distinguish whether the additional data is
present or not.

Daniel Dunbar c434394d18 Driver: Add -[no-]integrated-as for clang.

ddunbar@ozzy:tmp$ clang -m32 -integrated-as t.c

Benjamin Kramer 842bf17366 Use StringRef instead of returning a temporary std::string.
This fixes a really nasty bug in Darwin::getDarwinArchName where we were going
StringRef -> temporary std::string -> StringRef (and return the dead StringRef).
The StringRefs from Triple live as long as the Triple itself, that should be
long enough.

Hopefully 2 of 4 MSVC buildbot failures are gone now.

Daniel Dunbar 1299819f71 Driver: Don't honor -std-default for C++, this makes it hard to run the gdb test

work around for the gdb test suite.

llvm-svn: 94812
2010-01-29 17:02:25 +00:00
Douglas Gregor ac0605e927 Introduce serialization and deserialization of diagnostic information
so that CIndex can report diagnostics through the normal mechanisms
even when executing Clang in a separate process. This applies both
when performing code completion and when using ASTs as an intermediary
for clang_createTranslationUnitFromSourceFile().

The serialized format is not perfect at the moment, because it does
not encapsulate macro-instantiation information. Instead, it maps all
source locations back to the instantiation location. However, it does
maintain source-range and fix-it information. To get perfect fidelity
from the serialized format would require serializing a large chunk of
the source manager; at present, it isn't clear if this code will live
long enough for that to matter.

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...

Mike Stump d954638f02 Implement runtime checks for undefined behavior. WIP.
This implements a new flag -fcatch-undefined-behavior.  The flag turns

  T a[I];

  a[i]    abort when i < 0 or i >= I.

Future stuff includes shifts by >= bitwidth amounts.

Daniel Dunbar aa246cafaa Driver: Improve diagnostics for failed commands.
- Not all tools give good error messages, and sometimes the tool can fail w/o
   any error (for example, when signalled).

 - We suppress this message when the failing command is the compiler and it
   failed normally (exit code == 1), under the assumption that it gave a good
   diagnostic.

For example, for a linker failure we now get:
--
ddunbar@lordcrumb:tmp$ clang a.c b.c
ld: duplicate symbol _x in /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-bXYITq.o and /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-6uK4jD.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
--

For a compiler crash we get:
--
ddunbar@lordcrumb:tmp$ clang t.i
Assertion failed: (CGT.getTargetData().getTypeAllocSizeInBits(STy) == RL.getSize()), function layoutStructFields, file CodeGenTypes.cpp, line 573.
0   clang-cc          0x0000000100f1f1f1 PrintStackTrace(void*) + 38
... stack trace and virtual stack trace follow ...
clang: error: compiler command failed due to signal 6 (use -v to see invocation)
--

But for a regular compilation failure we get the usual:
--
ddunbar@lordcrumb:tmp$ clang c.c
c.c:1:6: error: invalid token after top level declarator
int x
     ^
1 diagnostic generated.
--

 - No test case, not amenable to non-executable testing. :/

planes, and a few other things.

Daniel Dunbar adeeb052ad Don't warn about -funit-at-a-time, and reject -fno-unit-at-a-time.
- We could just warn about -fno-unit-at-a-time, but in practice people using it
   probably aren't going to get what they want out of clang.

Also, use "clang" specified error for unsupported things instead of driver
unsupported error.

Daniel Dunbar e5ae096bf8 Tweak x86 -mcpu defaults.
- Default to yonah on Darwin (to get SSE3).

 - Default to Pentium4 (32-bit) and x86-64 (64-bit) on
   non-Darwin. Welcome to the 21st century.

llvm-svn: 71069
2009-05-06 04:58:14 +00:00
Daniel Dunbar 4dbaaa6f43 Improve handling of (X86) target features.
- This is a WIP...

 - This adds -march= handling to the driver, and fixes the defaulting
   of -mcpu on Darwin (which was using the wrong test).

Instead of handling -m{sse, ...} in the driver, pass them to clang-cc as
 -target-feature [+-]name

In clang-cc, communicate with the (clang) target to discover the legal
features of a target, and the features which are enabled based on
-mcpu. This is currently hardcoded just enough to not be a feature
regression, we need to get this information from the backend's
TableGen information somehow.

This is used to construct the full list of features which are being
used, which is in turn used to initialize the predefines.

2009-05-06 03:16:41 +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).

llvm-svn: 71056
2009-05-06 02:12:32 +00:00
Daniel Dunbar e993ba6fca Add -fobjc-tight-layout.
- This implements gcc style Objective-C interface layout (I
   think). Currently it is always off, there is no functionality
   change unless this is passed.
   
   For the curious, the deal is that gcc lays out the fields of a
   subclass as if they were part of the superclass. That is, the
   subclass fields immediately follow the super class fields instead
   of being padded to the alignment of the superclass structure.

 - Currently gcc uses the tight layout in 32-bit and 64-bit modes, and
   llvm-gcc uses it in 32-bit only, for reasons which aren't clear
   yet. We probably want to switch to matching gcc, once this makes it
   through testing... my hope is that we can also fix llvm-gcc in
   order to maintain compatibility between the compilers.

Daniel Dunbar 5716d87ed1 Driver: When using the generic gcc tool, pass -m32 or -m64 if we

Douglas Gregor 4818553abd Implement -fmessage-length=N, which word-wraps diagnostics to N columns.
Also, put a line of whitespace between the diagnostic and the source
code/caret line when the start of the actual source code text lines up
(or nearly lines up) with the most recent line of the diagnostic. For
example, here it's okay for the last line of the diagnostic to be
(vertically) next to the source line, because there is horizontal
whitespace to separate them:

decl-expr-ambiguity.cpp:12:16: error: function-style cast to a builtin
      type can only take one argument
  typeof(int)(a,5)<<a;

However, here is a case where we need the vertical separation (since
there is no horizontal separation):

message-length.c:10:46: warning: incompatible pointer types initializing 'void
      (int, float, char, float)', expected 'int (*)(int, float, short,
      float)'

      int (*fp1)(int, float, short, float) = f;

This is part one of <rdar://problem/6711348>.

   modify the build system.

Daniel Dunbar c1b1b4b2c9 Don't run dsymutil when making a fat executable direct source.
- Otherwise, we will end up with stray .dSYM files which don't get
   lipo'ed or removed.

 - Ideally we would run dsymutil on the result, but we don't have the
   infrastructure for that yet. Note that gcc doesn't handle this case
   either.
