link.exe: Fuzz testing has shown that COMMON symbols with size > 32 will always have an alignment of at least 32 and all symbols with size < 32 will have an alignment of at least the largest power of 2 less than the size of the symbol. binutils: The BFD linker essentially work like the link.exe behavior but with alignment 4 instead of 32. The BFD linker also supports an extension to COFF which adds an -aligncomm argument to the .drectve section which permits specifying a precise alignment for a variable but MC currently doesn't support editing .drectve in this way. With all of this in mind, we decide to play a little trick: we can ensure that the alignment will be respected by bumping the size of the global to it's alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218201 91177308-0d34-0410-b5e6-96231b3b80d8
