an odd number.

Anders Carlsson 8a01a751c9 Remove CK_DynamicToNull. 
llvm-svn: 129265
 2011-04-11 02:03:26 +00:00
Anders Carlsson c1c9971cab When we know that a dynamic_cast always returns null, we can make 
CodeGenFunction::EmitDynamicCast always return null or throw a bad_cast 
exception.

Anders Carlsson 50ddb5cc0a Remove the CodeGenCXX/dyncast.cpp test; it isn't really super useful to match on huge chunks of LLVM output.

Anders Carlsson c602006638 As a first step towards fixing PR9641, add a CK_DynamicToNull cast kind which 
represents a dynamic cast where we know that the result is always null.

For example:

struct A {
  virtual ~A();
};
struct B final : A { };
struct C { };

bool f(B* b) {
  return dynamic_cast<C*>(b);
}

Chandler Carruth 016ef400c4 Enhance the diagnostic for literal float -> int conversions to suggest 
rewriting the literal when the value is integral. It is not uncommon to
see code written as:

  const int kBigNumber = 42e5;

Without any real awareness that this is no longer an ICE. The note helps
automate and ease the process of fixing code that violates the warning.

Eli Friedman 493c34a86c PR9580: Handle vectors correctly in ScalarExprEmitter::EmitRem. 
While I'm here, FileCheck-ize the ext-vector test, so we actually check

Francois Pichet 53fe2bb29e MSVC accepts that default parameters be redefined for member functions 
of template class. The new value is ignored.

Oscar Fuentes 87eb515aba libclang output name is now libclang. This solves a name collision 
when building with Visual Studio. `clang.dll' and `clang.exe' would
have the same `clang.ilk' and `clang.pdb'. On a serial build those
files would be overwritten as clang.exe/clang.dll are created. On a
parallel build there is a risk of both files being written at the same
time. On that case VS fails.

Bill Wendling 3d5450d809 Beginning of the Great Exception Handling Rewrite. 
* Add a "landing pad" attribute to the BasicBlock.
* Modify the bitcode reader and writer to handle said attribute.

Later: The verifier will ensure that the landing pad attribute is used in the
appropriate manner. I.e., not applied to the entry block, and applied only to
basic blocks that are branched to via a `dispatch' instruction.

(This is a work-in-progress.)

Chris Lattner 077f0179bb LLVMCC_EMITIR_FLAG is already either -emit-llvm or -fplugin-arg-dragonegg-emit-ir, so don't add an extra leading -. Clang doesn't accept --emit-llvm.

Chris Lattner fc4fe00a65 fix rdar://8735979 - "int 3" doesn't match to "int3". Unfortunately, 
InstAlias doesn't allow matching immediate operands, so we have to write
C++ code to do this.

Lenny Maiorani 467dbd5f13 strcat() and strncat() model additions to CStringChecker. 
Validates inputs are not NULL, checks for overlapping strings, concatenates the strings checking for buffer overflow, sets the length of the destination string to the sum of the s1 length and the s2 length, binds the return value to the s1 value.

Dylan Noblesmith 92c07c27be refactor flags for TokenKinds.def 
Make KEYALL a combination of all other flags instead
of its own separate flag. Also rewrite the enum
definitions in hex instead of decimal.

Dylan Noblesmith 70e73a3d60 refactor -ccc-gcc-name code 
Put the logic for deciding the default name for gcc/g++
in the only place that actually cares about it.

This also pushes an ifdef out of the generic driver code
to a little further down, when the target is actually known.
Hopefully it can be changed into just a runtime check
in the future.

Chandler Carruth 66a7b04767 Clean up the bool conversion warning. Group it with other conversion 
warnings, and make its text appropriate for constant bool expressions
other than 'false'. This should finish off PR9612.

llvm-svn: 129205
 2011-04-09 07:48:17 +00:00
Chandler Carruth ffab873ed5 Add support for warning on general null pointer expressions of boolean 
type rather than just the literal 'false'. This begins fixing PR9612,
but the message is now wrong. WIP, the cleanup of the messaging is next.
