Mike Stump 37dbe96a06 Track the offset to the current virtual base in CurrentVBaseOffset. 
Track path information completely to ensure we get all the overrides.  WIP.

llvm-svn: 84166

Anders Carlsson 66413c29d3 Handle 
struct A { };
struct B : A { };

void f() {
  const A& a = B();
}

correctly. (This now does the offset conversion if necessary and calls the destructor when a goes out of scope).

Mike Stump b21c4eede4 Shift the vcall slots for non-virtual bases of a virtual base, up into 
the virtual base so they can be reused properly.  Don't reuse vcall
slots across a virtual boundary.  WIP.  I have a testcase, but there
are still things that need to be fixed before the testcase can go in.

Sanjiv Gupta 84a0287497 Few targets like PIC16 mangle the names of global variables, so retrieve the name 
from Var itself rather than the decl for DebugInfo metadata.

Chris Lattner 4f8a2e22c0 fix some cfstring related issues: 
1) -fwritable-string does affect the non-utf16 version of cfstrings
   just not the utf16 ones.
2) utf16 strings should always be marked constant, as the __TEXT segment
   is readonly.
3) The name of the global doesn't matter, remove it from TargetInfo.
4) Trust the asmprinter to drop cstrings into the right section, like llvmgcc does now.

This fixes rdar://7115750

Benjamin Kramer abd5b90e4c Simplify pointer creation with the new Type::getInt*Ptr methods. 
llvm-svn: 83964
 2009-10-13 10:07:13 +00:00
Chris Lattner 3eb172a02b Teach sema and codegen about the difference between address of labels, 
which is a common idiom to improve PIC'ness of code using the addr of
label extension.  This implementation is a gross hack, but the only other
alternative would be to teach evalutate about this horrid combination.
While GCC allows things like "&&foo - &&bar + 1", people don't use this
in practice.  This implements PR5131.

llvm-svn: 83957
 2009-10-13 07:14:16 +00:00
Chris Lattner 2bb5cb490c reimplement codegen for indirect goto with the following advantages: 
1. CGF now has fewer bytes of state (one pointer instead of a vector).
2. The generated code is determinstic, instead of getting labels in
   'map order' based on pointer addresses.
3. Clang now emits one 'indirect goto switch' for each function, instead
   of one for each indirect goto.  This fixes an M*N = N^2 IR size issue
   when there are lots of address-taken labels and lots of indirect gotos.
4. This also makes the default cause do something useful, reducing the
   size of the jump table needed (by one).

llvm-svn: 83952
 2009-10-13 06:55:33 +00:00
Chris Lattner 92ae16b0ae number address-taken labels from 1. This allows 0 to be used as a sentinel 
for a null pointer.  In other words, "&&foo != NULL" will always work out to
true.

llvm-svn: 83948
 2009-10-13 06:04:29 +00:00
Chris Lattner dd7eaad7d4 Use the new Type::getInt8PtrTy method. This should probably be used in a lot

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. :)
