98749f851d In this unreachable code, return an initialized value.
This stops gcc warning about possible uses of an uninitialized
value when compiling with assertions turned off.

1d2e6ed1ef For extended loads of type i1 to i8, we will need to at least one byte from memory.
The change in the .td file is to mark the side effects of mov insn.

6a3a1ba97e Various small changes related to the Condition Register on PowerPC.
Don't spill to the CR save area when using the SVR4 ABI for now.
Don't rely on constants assigned for registers to be in order (they aren't assigned in order).
Make sure CR bits are mapped to the corresponding CR field.

2a9ddfb903 Refactor ABI code in the PowerPC backend.
Make CalculateParameterAndLinkageAreaSize() Darwin-specific.
Remove SVR4 specific code from LowerCALL_Darwin() and LowerFORMAL_ARGUMENTS_Darwin().
Rename MachoABI to DarwinABI for consistency.
Rename ELF ABI to SVR4 ABI for consistency.
Factor out common call return lowering between the Darwin and SVR4 ABI.
Factor out common call lowering between the Darwin and SVR4 ABI.

ffd0200abf Implement the SVR4 ABI for PowerPC.
Implement LowerFORMAL_ARGUMENTS_SVR4().
Implement LowerCALL_SVR4().
Add support for split arguments.
Implement by value parameter passing for aggregates.
Add support for variable argument lists.
Create the spill area for argument registers of variable argument functions no longer at a fixed offset.
Make sure callee saved registers are spilled to the correct stack offsets.
Change allocation order of non-volatile floating-point registers.
Add VRSAVE to the list of callee-saved registers, add CallConvLowering for vararg calls.
Add support for variable argument calls with Vector arguments.
Add support for VR and VRSAVE save area, improve allocation order for non-volatile vector registers.
Stop creating illegal i8 values in LowerVASTART().
Add memory access width hints.
Make sure to reserve space on the stack for the frame pointer.
When using the SVR4 ABI, reserve r13 for the Small Data Area pointer.
Assure that the frame pointer is spilled to the correct location on the stack.
Some FP registers were not marked as volatile.
Make sure the i64 words from a long double are passed either both in registers or both on the stack.
Only put integer arguments in registers which are not marked with the inreg flag.

6b61cd185e Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed arguments in a vararg call.
With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put 
into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack.

The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list.

it to print them.  This gives us column numbers in the diag line.  Before:

t.s:4: error: unexpected token in argument list
 mov %eax %edx
          ^

now:
t.s:4:11: error: unexpected token in argument list
 mov %eax %edx
