this.

Evan Cheng 6ab54fdb0a Fix Thumb2 function call isel. Thumb1 and Thumb2 should share the same 
instructions for calls since BL and BLX are always 32-bit long and BX is always
16-bit long.

Also, we should be using BLX to call external function stubs.

Bob Wilson 84aa855ead Allow target intrinsics that return multiple values, i.e., struct types, 
in SelectionDAGLowering::visitTargetIntrinsic.

This removes a bit of special-case code for vector types.  After staring
at it for a while, I managed to convince myself that it is not necessary.
The only case where TLI.getValueType() differs from MVT::getMVT is for iPTR,
so this code could potentially make a difference for a vector of pointers.
But, it looks like that is not supported.  Calling TLI.getValueType() on
a vector of pointers leads to the following sequence of calls:

TargetLowering::getValueType
MVT::getMVT
MVT::getVectorVT(iPTR, num elements)
MVT::getExtendedVectorVT
MVT::getTypeForMVT for iPTR
assertion fails "Type is not extended!"

So, unless I'm really missing something, this bit of code is irrelevant to
the current version of LLVM, which is consistent with the fact that I don't
see this code in other similar places.

Daniel Dunbar a4fc8d94ce llvm-mc: A few more parsing / match tweaks. 
- Operands which are just a label should be parsed as immediates, not memory
   operands (from the assembler perspective).

 - Match a few more flavors of immediates.

 - Distinguish match functions for memory operands which don't take a segment
   register.

 - We match the .s for "hello world" now!

Chris Lattner f4b92a8a00 add some comments on how this is *supposed* to work. We don't 
need the PreferredEHDataFormat hook, but I have yet-more refactoring to
do before I can zap it.

David Greene 81bcae5fda Simplify operand padding by keying off tabs in the asm stream. If 
padding is disabled, tabs get replaced by spaces except in the case of
the first operand, where the tab is output to line up the operands after
the mnemonics.

Add some better comments and eliminate redundant code.

Fix some testcases to not assume tabs.

Chris Lattner 63779b8d57 PreferredEHDataFormat is always call with data and global, but this whole
