llvm-svn: 83221
 2009-10-01 22:29:41 +00:00
Douglas Gregor 369acf9304 CodeGen may see out-of-line declarations of the various special member 
functions when they are explicitly declared, e.g., via a function
template specialization or explicit template instantiation
declaration. Don't try to synthesize bodies for the special member
functions in this case; rather, check whether we have an implicit
declaration and, if so, synthesize the appropriate function
body. Fixes PR5084.

path.  There's a bit of simplifications yet to do as well.

llvm-svn: 83138
 2009-09-30 02:43:10 +00:00
Douglas Gregor bb3e12fc0b Handle C++ delete expressions when the overloaded delete operator is a 
"usual deallocation function" with two arguments. CodeGen will have to
handle this case specifically, since the value for the second argument
(the size of the allocated object) may have to be computed at run
time.

Fixes the Sema part of PR4782.

Daniel Dunbar ff0553ec61 Fix subtle bug in generating LLVM function declarations for builtin functions. 
The decl wasn't being passed down, which meant that function attributes were not
being set correctly. This is particularly important for ARM, since it wants to
override the calling convention. Instead we would emit the builtin with the
wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

created at all; patch to follow.

This will let us do things like verify that tags match during
template instantation, as well as signal that an elaborated type
specifier was used for clients that actually care.

Optimally, the TypeLoc hierarchy should be adjusted to carry tag
location information as well.

Mike Stump a5588bf3ac Implement virtual dispatch. :-) This is self-consistent with clang, 
but not yet necessarily perfectly consistent with gcc.  Also addressed
Doug and John's comments.

Eli Friedman 95f896380f Make address-space qualification work correctly for compound literals. 
Issue reported on cfe-dev.

Also fixed the code to use isConstant to determine whether to generate a 
constant global, to be consistent with CodeGenModule.  This probably 
needs to be refactored to deal with C++, though.
