2010-10-26First part of refactoring ARM addrmode2 (load/store) instructions to be moreJim Grosbach
explicit about the operands. Split out the different variants into separate instructions. This gives us the ability to, among other things, assign different scheduling itineraries to the variants. rdar://8477752. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117409 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-26After splitting, compute connected components of all new registers, not just forJakob Stoklund Olesen
the remainder register. Example: bb0: x = 1 bb1: use(x) ... x = 2 jump bb1 When x is isolated in bb1, the inner part breaks into two components, x1 and x2: bb0: x0 = 1 bb1: x1 = x0 use(x1) ... x2 = 2 x0 = x2 jump bb1 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117408 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-26Change v64 datalayout in SPU.Kalle Raiskila
The SPU ABI does not mention v64, and all examples in C suggest v128 are treated similarily to arrays, we use array alignment for v64 too. This makes the alignment of e.g. [2 x <2 x i32>] behave "intuitively" and similar to as if the elements were e.g. i32s. This also makes an "unaligned store" test to be aligned, with different (but functionally equivalent) code generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117360 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-26When the "true" and "false" blocks of a diamond if-conversion are the same,Bob Wilson
do not double-count the duplicate instructions by counting once from the beginning and again from the end. Keep track of where the duplicates from the beginning ended and don't go past that point when counting duplicates at the end. Radar 8589805. This change causes one of the MC/ARM/simple-fp-encoding tests to produce different (better!) code without the vmovne instruction being tested. I changed the test to produce vmovne and vmoveq instructions but moving between register files in the opposite direction. That's not quite the same but predicated versions of those instructions weren't being tested before, so at least the test coverage is not any worse, just different. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117333 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-26Change if-conversion to keep track of the extra cost due to microcodedBob Wilson
instructions separately from the count of non-predicated instructions. The instruction count is used in places to determine how many instructions to copy, predicate, etc. and things get confused if that count includes the extra cost for microcoded ops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117332 91177308-0d34-0410-b5e6-96231b3b80d8
