Are you sure this is right? In section 5.31 of the GCC Manual it
indicates that if an alignment size is not given with the aligned
attribute keyword then it defaults to:
the maximum useful alignment for the target machine you are compiling
for. Whenever you leave out the alignment factor in an `aligned'
attribute specification, the compiler automatically sets the alignment
for the declared variable or field to the largest alignment which is
ever used for any data type on the target machine you are compiling
for.
Is this what we want here?
Reid.

This compiled on my 3.4.6 compiler on Linux just fine before the patch. What was the error you were trying to fix? Allignment Value not constant was the error. This was gcc 3.4.4 Are you sure this is right? In section 5.31 of the GCC Manual it indicates that if an alignment size is not given with the aligned attribute keyword then it defaults to: the maximum useful alignment for the target machine you are compiling for. Whenever you leave out the alignment factor in an `aligned' attribute specification, the compiler automatically sets the alignment for the declared variable or field to the largest alignment which is ever used for any data type on the target machine you are compiling for. Is this what we want here? I believe so. The alignment of that field needs to be sufficient for any data type put there. The non-gcc version does that with a union. My reading of the gcc manual is that without a value, this attribute does exactly that (and since doubles are not always the most constrained types, vectors tend to be, this is more general, though I doubt altivec vectors are going to be used directly by LLVM in small vectors anytime soon).

Added LoadSDNode to represent load nodes. Chain and address ptr remains as operands. SrcValue, extending mode, extending VT (or rather loaded VT before extension) are now instance variables of LoadSDNode. Introduce load / store addressing modes to represent pre- and post-indexed load and store. Also added an additional operand offset that is only used in post-indexed mode (i.e. base ptr += offset after load/store).
