Ismail Pazarbasi 1121de36c2 Fix string-literal to char* conversion in overload resolution for C++11 
String literal to char* conversion is deprecated in C++03, and is removed in
C++11. We still accept this conversion in C++11 mode as an extension, if we find
it in the best viable function.

Jason Molenda be1261a1ab Add -stdlib=c++ to the LDFLAGS when configuring llvm. The lldb 
xcode project file sets the MACOSX_DEPLOYMENT_TARGET to 10.7.
llvm/configure (as of r199313) tries to compile a .cpp file which
includes <atomic> with -std=c++0x.  If the deployment target is set
to earlier than 10.9 and no C++ library is specified, clang will
error out at this point.

Fixes xcode building of lldb on Mac OS X.  If this change causes
problems for any of the other build workflows, please let me know
and I'll fix it.

Todd Fiala f3d61de532 Enable Linux distribution in vendor portion of host triple. 
This change does the following:

* enables building lldb-gdbserver on linux_x86-64 platforms.

  Note - it builds but it has several run-time issues where many gdb
  remote protocol features are not properly implemented yet. I'm
  working on these one at a time.

* lldb-gdbserver: does not enable the eLaunchFlagDebug launch flag on
  Linux. Currently the POSIX launch routine will assert if that flag
  is passed in, presumably because that launch mode is not yet
  available.  This prevents lldb-gdbserver from asserting the moment
  it launches the debuggee process.

* Adds ConstString& Host::GetDistributionId ()

  This method is defined to return an empty result on all platforms
  except for Linux.  On Linux, it makes one attempt to execute
  'lsb_release -i' (both /usr/bin/lsb_release, where it appears
  on ubuntu, and /bin/lsb_release, where it appears on fedora
  if the redhat-lsb package is installed).  If lsb_release is not
  found in either of those locations, or if 'lsb_release -i' does
  not return the first line starting with "Distributor ID:\t",
  then the distribution id is empty.  The method will lower-case
  the id and replace whitespace with underscores.

* Modify Host::GetArchitecture () so that linux replaces an unknown
  vendor portion with the results of GetDistributionId () if that
  is non-empty.  This shows up now in qHostInfo remote packet
  responses and on the lldb host side.  Tested with ubuntu and
  fedora (the latter both with the default of not having lsb_release
  installed, and with having lsb_release installed via the redhat-lsb
  package).

  Examples of triples on Linux after this change:

    # x86_64 Unbuntu 12.04 LTS:
    x86_64-ubuntu-linux-gnu

    # x86_64 Fedora 20 Desktop with redhat-lsb package installed
    x86_64-fedora-linux-gnu

    # x86_64 Fedora 20 Desktop without redhat-lsb-core installed
    # (i.e. no /bin/lsb_release available)
    # same as before the change
    x86_64--linux-gnu

  Note I intend to have Android respond with:

    {arch}-android-linux

  when I get to implementing Android lldb-gdbserver support.

Juergen Ributzka e625013071 Add two new calling conventions for runtime calls 
This patch adds two new target-independent calling conventions for runtime
calls - PreserveMost and PreserveAll.
The target-specific implementation for X86-64 is defined as following:
  - Arguments are passed as for the default C calling convention
  - The same applies for the return value(s)
  - PreserveMost preserves all GPRs - except R11
  - PreserveAll preserves all GPRs and all XMMs/YMMs - except R11

Steve Pucci fc99572540 Rename Platform::GetFile (3-arg version) to GetFileWithUUID 
This rename was suggested by gclayton as a way to silence gcc
warnings; the warning is emitted when there is an overloaded function
in a base class (Platform) for which a derived class redefines one of
the overloads but not the other (because doing so hides the other
overload from users of the derived class).  By giving the two methods
different names, the situation is avoided.

Kostya Serebryany 714c67c31e [asan] extend asan-coverage (still experimental). 
- add a mode for collecting per-block coverage (-asan-coverage=2).
   So far the implementation is naive (all blocks are instrumented),
   the performance overhead on top of asan could be as high as 30%.
 - Make sure the one-time calls to __sanitizer_cov are moved to function buttom,
   which in turn required to copy the original debug info into the call insn.

Here is the performance data on SPEC 2006
(train data, comparing asan with asan-coverage={0,1,2}):

Chandler Carruth 7677760ec8 [PM] Remove the preverifier and directly compute the DominatorTree for 
the verifier after ensuring the CFG is at least usefully formed.

This fixes a number of problems:
1) The PreVerifier was missing the controls the Verifier provides over
   *how* an invalid module is handled -- it just aborted the program!
   Now it uses the same logic as the Verifier which is significantly
   more library-friendly.
2) The DominatorTree used previously could have been cached and not
   updated due to bugs in prior passes and we would silently use the
   stale tree. This could cause dominance errors to not be as quickly
   diagnosed.
3) We can now (in the next patch) pull the functionality of the verifier
   apart from the pass infrastructure so that you can verify IR without
   having any form of pass manager. This in turn frees the code to share
   logic between old and new pass manager variants.

Along the way I fixed at least one annoying bug -- the state for
'Broken' wasn't being cleared from run to run causing all functions
visited after the first broken function to be marked as broken
regardless of whether *they* were a problem. Fortunately, I don't really
know much of a way to observe this peculiarity.

In case folks are worried about the runtime cost, its negligible.
I looked at running the entire regression test suite (which should be
a relatively good use of the verifier) before and after but was unable
to even measure the time spent on the verifier and there was no
regresion from before to after. I checked both with debug builds and
optimized builds.

Ted Kremenek 9aedc159ef Enhance attribute 'nonnull' to be applicable to parameters directly (infix). 
This allows the following syntax:

  void baz(__attribute__((nonnull)) const char *str);

instead of:

  void baz(const char *str) __attribute__((nonnull(1)));

This also extends to Objective-C methods.

The checking logic in Sema is not as clean as I would like.  Effectively
now we need to check both the FunctionDecl/ObjCMethodDecl and the parameters,
so the point of truth is spread in two places, but the logic isn't that
cumbersome.

Implements <rdar://problem/14691443>.

Ted Kremenek 07e4a66306 Add ArrayRef<> interface to get the parameters of a FunctionDecl/ObjCMethodDecl. 
This is an alternate interface to the separate iterator interfaces
provided by FunctionDecl and ObjCMethodDecl, which precede ArrayRef.

Providing this new interface is more convenient for some uses, and
likely the old interfaces should be removed.  I have not undertaken
that effort in this change because this API introduction may
solicit commentary and that was a larger change than I wanted
to introduce all at once to serve a direct purpose.
