| | | | | | | | | | | | | | | | 2. Using zero-extended value of Scale and unsigned division is safe provided that Scale doesn't have the sign bit set. Previously these 2 instructions: %p = bitcast [100 x {i8,i8,i8}]* %x to i8* %q = getelementptr i8* %p, i32 -4 were combined into: %q = getelementptr [100 x { i8, i8, i8 }]* %x, i32 0, i32 1431655764, i32 0 what was incorrect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44936 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement address space attribute for LLVM pointer types. Address spaces are Christopher Lamb2007-12-1115-43/+151
| | | | | | | | | | | | | | | | | | regions of memory that have a target specific relationship, as described in the Embedded C Technical Report. This also implements the 2007-12-11-AddressSpaces test, which demonstrates how address space attributes can be used in LLVM IR. In addition, this patch changes the bitcode signature for stores (in a backwards compatible manner), such that the pointer type, rather than the pointee type, is encoded. This permits type information in the pointer (e.g. address space) to be preserved for stores. LangRef updates are forthcoming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44858 91177308-0d34-0410-b5e6-96231b3b80d8
