* Implement support for non-standard integer bit widths of any size. TheReid Spencer2007-02-192-16/+39
| | | | | | | | | | | | | | rules alignment is to pick the alignment that corresponds to the smallest specified alignment that is larger than the bit width of the type or the largest specified integer alignment if none are larger than the bitwidth of the type. For the byte size, the size returned is the next larger multiple of the alignment for that type (using the above rule). This patch also changes bit widths from "short" to "uint32_t" to ensure there are enough bits to specify any bit width that LLVM can handle (currently 2^23); 16-bits isn't enough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34431 91177308-0d34-0410-b5e6-96231b3b80d8

Remove the non-const overload of the getWord function, getWord() is never used as an lvalue. 4.

Fix indentation per coding standards. 8.
