2011-06-13It's possible that an all-zero GEP may be used as the argument to lifetimeNick Lewycky
intrinsics. In fact, we'll optimize a bitcast to that when possible. Detect it when looking for the lifetime intrinsics. No test case, noticed by inspection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132906 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-13Be less aggressive about hinting in RAFast.Jakob Stoklund Olesen
In particular, don't spill dirty registers only to satisfy a hint. It is not worth it. The attached test case provides an example where the fast allocator would spill a register when other registers are available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132900 91177308-0d34-0410-b5e6-96231b3b80d8

types such as i33 were rounded to i32. Originated from Duncan's testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132893 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-12Improve the generated code by getCopyFromPartsVector for promoted integer types.Nadav Rotem
Instead of scalarizing, and doing an element-by-element truncat, use vector truncate. Add support for scalarization of vectors: i8 -> <1 x i1> (from Duncan's testcase). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132892 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-12Tweak hash function and compress hash tables.Jakob Stoklund Olesen
Make the hash tables as small as possible while ensuring that all lookups can be done in less than 8 probes. Cut the aliases hash table in half by only storing a < b pairs - it is a symmetric relation. Use larger multipliers on the initial hash function to ensure that it properly covers the whole table, and to resolve some clustering in the very regular ARM register bank. This reduces the size of most of these tables by 4x - 8x. For instance, the ARM tables shrink from 48 KB to 8 KB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132888 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-12Extract the generateHashTable function.Jakob Stoklund Olesen
The constant hash tables for sub-registers and overlaps are generated the same way, so extract a function to generate and print the hash table. Also use the information computed by CodeGenRegisters.cpp instead of the locally data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132886 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-12Compute lists of sub-regs, super-regs, and overlapping regs.Jakob Stoklund Olesen
Besides moving structural computations to CodeGenRegisters.cpp, this also well-defines the order of these lists: - Sub-register lists come from a pre-order traversal of the graph defined by the SubRegs lists in the .td files. - Super-register lists are topologically ordered so no register comes before any of its sub-registers. When the sub-register graph is not a tree, independent super-registers appear in numerical order. - Lists of overlapping registers are ordered according to register number. This reverses the order of the super-regs lists, but nobody was depending on that. The previous order of the overlaps lists was odd, and it may have depended on the precise behavior of std::stable_sort. The old computations are still there, but will be removed shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132881 91177308-0d34-0410-b5e6-96231b3b80d8
