New CallInst interface to address GLIBCXX_DEBUG errors caused by
indexing an empty std::vector.

Updates to all clients.

so must be lowered to a value, not nothing at all.
Subtle point: I made eh_selector return 0 and
eh_typeid_for return 1.  This means that only
cleanups (destructors) will be run as the exception
unwinds [if eh_typeid_for returned 0 then it would
be as if the first catch always matched, and the
corresponding handler would be run], which is
probably want you want in the CBE.

Make sure that the CTPOP result is casted to i32 as the bit counting
intrinsics all return i32 now (this affects CTLZ and CTTZ as well).

1. Memset takes an i32 for the value to set, not i8.  This was causing GCC to
   ICE all over the place (PR1183).
2. memcpy/memmove were not properly zext/trunc'ing the size in some cases.

This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

confusion with external linkage types.

llvm-svn: 33663

functions like memcpy, memmove and memset. Ensure only one prototype is
used for these functions and that it matches the system definition by
using the appropriate type for the size argument.

llvm-svn: 33618

Force memcpy to be the 32-bit variant. Since this is only used with
CBE and lli which both target 32-bit machines, this should be okay.

llvm-svn: 33608

rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)

Change the interface to Module::getOrInsertFunction to be easier to use,to resolve PR1088, and to help PR411.
This simplifies many clients also

llvm-svn: 32989

Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
   type of an function parameter was used to determine whether it should
   be sign extended or zero extended before the call. This information is
   now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
   the parameter attribute information. Although it would have been
   convenient to pass in the FunctionType itself, there isn't always one
   present in the caller. Consequently, a signedness indication for the
   result type and for each parameter was provided for in the interface
   to this method. All implementations were changed to make the adjustment
   necessary.

llvm-svn: 32788

This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

creation. These changes are still temporary but at least this pushes
knowledge of signedness out closer to where it can be determined properly
and allows signedness to be removed from VMCore.
