Mike Stump fd84d6d808 Fix ctor vtable name. WIP. 
llvm-svn: 86879
 2009-11-11 20:32:03 +00:00
Mike Stump eac4559790 Push ctor vtable construction down further. WIP.

Devang Patel 5348515193 Do not eagerly set stop point for arguments. This misleads the debugger in identifying beginning of function body. Instead, create new location to attach with llvm.dbg.declare. This location is only used to find the context of the variable by the code generator, and it is not used to emit line number info.

Fariborz Jahanian 03f62ed9bb Value initialize non-class array members in ctor's

necessary.

Eli Friedman 3ad2645430 Fix for PR5454: make sure to use the right block as the predecessor in the 
generated PHI node for the null check of a new operator.

Douglas Gregor 4ef1d400d9 Make sure that Type::getAs<ArrayType>() (or Type::getAs<subclass of 
ArrayType>()) does not instantiate. Update all callers that used this
unsafe feature to use the appropriate ASTContext::getAs*ArrayType method.

Eli Friedman cc522d9ab3 Rearrange function to avoid recursive use-after-free. 
llvm-svn: 86516
 2009-11-09 05:07:37 +00:00
Eli Friedman a72bf0fae8 Explicitly note that pre-inc/dec lvalues are not supported yet, so that it 
doesn't crash.  (Such expressions are valid in C++, but not in C.)

llvm-svn: 86513
 2009-11-09 04:20:47 +00:00
Daniel Dunbar 11c08c8e5b Rename areAllFields32Or64BitBasicType to canExpandIndirectArgument to closer match what it is semantically used for. 
Also, fix a major bug where fields from a C++ struct might be dropped -- the expand action doesn't handle them correctly yet.

llvm-svn: 86502
 2009-11-09 01:33:53 +00:00
Eli Friedman d7686ef31c Unify the codepaths used to verify base and member initializers for explicitly 
and implicitly defined constructors.  This has a number of benefits:

1. Less code.

2. Explicit and implicit constructors get the same diagnostics.

3. The AST explicitly contains constructor calls from implicit default
constructors.  This allows handing some cases that previously weren't handled
correctly in IRGen without any additional code. Specifically, implicit default
constructors containing calls to constructors with default arguments are now
handled correctly.

 2009-11-07 00:29:05 +00:00
