[llvm-dev] Alignment of the StoreInst

[Hongbin Zheng via llvm-dev]

Hi all,

I am wondering the semantics of alignment in a StoreInst. For example, in
the following code:

  %A = bitcast i8* %buffer to i32*
  store i32 %x, i32* %A, align 4

We have an "align 4" in the StoreInst. Does this mean
1) the address 'A' should be aligned to 4 bytes?
2) the lower 2 bits of 'A' should be always 0?

Thanks
Hongbin
