04a7716d62 While passing arg of types larger than char only one byte at lower end was getting passed. We couldn't catch this as we did not have tests that were passing an int value larger than 256.

14c26ced49 The way we are trying to figure out banksel immediate operand may yield different results for different type of insns. This will eventually need to be changed but currently let us prevent the crash in cases of incorrect detection of banksel operand.

bbb78a0034 Handle indirect function calls. 
Every function has the address of its frame in the beginning of code section.
The frame address is retrieved and used to pass arguments.

14d86f7755 Map stack based frameindices for spills to zero based indices that can be accessed based on an external symbol defining the location of temporary data for a function. For example: we have spill slots addressed as foo.tmp + 0, foo.tmp + 1 etc.

01fb90085c To convert the StopPoint insn into an assembler directive by ISel, we need to have access to the line number field. So we convert that info as an operand by custom handling DBG_STOPPOINT in legalize.

1555a0a503 Params are not being generated as static globals now. The caller passes them onto the callee's stack directly and the callee loads the argvals from its own stack. Clang generated frameindexes validatd by recalculating the stack as if all frameindexes represent 1-byte slots.

9d4eb136da Overhaul my earlier submission due to feedback. It's a large patch, but most of 
them are generic changes.

- Use the "fast" flag that's already being passed into the asm printers instead
  of shoving it into the DwarfWriter.

- Instead of calling "MI->getParent()->getParent()" for every MI, set the
  machine function when calling "runOnMachineFunction" in the asm printers.

abf1d4e9db Function temporaries can not overlap with retval or args.See the comment in source code to know the reason. Anything having .auto. in its name is local to a function in nature irrespective of the linkage specified. print static local variables in module level IDATA section.

a259483aae Get rid of the last non-DebugLoc versions of getNode! 
Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base.  There's no
sensible way to associate debug info with these.  I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. 
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.

1580ab6b7f Remove more non-DebugLoc getNode variants. Use 
getCALLSEQ_{END,START} to permit passing no DebugLoc
there.  UNDEF doesn't logically have DebugLoc; add
getUNDEF to encapsulate this.

e442452ade Enable emitting of constant values in non-default address space as well. The APIs emitting constants now take an additional parameter signifying the address space in which to emit. The APIs like getData8BitsDirective() etc are made virtual enabling targets to be able to define appropirate directivers for various sizes and address spaces.

6fcee67989 Move a few containers out of ScheduleDAGInstrs::BuildSchedGraph 
and into the ScheduleDAGInstrs class, so that they don't get
destructed and re-constructed for each block. This fixes a
compile-time hot spot in the post-pass scheduler.

To help facilitate this, tidy and do some minor reorganization
in the scheduler constructor functions.

1fae2ea219 Change the interface to the type legalization method 
ReplaceNodeResults: rather than returning a node which
must have the same number of results as the original
node (which means mucking around with MERGE_VALUES,
and which is also easy to get wrong since SelectionDAG
folding may mean you don't get the node you expect),
return the results in a vector.
