2013-04-12ARM: Correct printing of pre-indexed operands.Quentin Colombet
According to the ARM reference manual, constant offsets are mandatory for pre-indexed addressing modes. The MC disassembler was not obeying this when the offset is 0. It was producing instructions like: str r0, [r1]!. Correct syntax is: str r0, [r1, #0]!. This change modifies the dumping of operands so that the offset is always printed, regardless of its value, when pre-indexed addressing mode is used.

2013-04-12PPC: Remove (broken) nested implicit definition listsHal Finkel
TableGen will not combine nested list 'let' bindings into a single list, and instead uses only the inner scope. As a result, several instruction definitions were missing implicit register defs that were in outer scopes. This de-nests these scopes and makes all instructions have only one let binding which sets implicit register definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179392 91177308-0d34-0410-b5e6-96231b3b80d8

Don't classify idiv/udiv as a reduction operation. Integer division is lossy. For example : (1 / 2) * 4 != 4/2.

2013-04-12Add PPC instruction record forms and associated query functionsHal Finkel
This is prep. work for the implementation of optimizeCompare. Many PPC instructions have 'record' forms (in almost all cases, this means that the RC bit is set) that cause the result of the instruction to be compared with zero, and the result of that comparison saved in a predefined condition register. In order to add the record forms of the instructions without too much copy-and-paste, the relevant functions have been refactored into multiclasses which define both the record and normal forms. Also, two TableGen-generated mapping functions have been added which allow querying the instruction code for the record form given the normal form (and vice versa). No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179356 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-12Add a flag to align all basic blocks in the function.Nadav Rotem
When debugging performance regressions we often ask ourselves if the regression that we see is due to poor isel/sched/ra or due to some micro-architetural problem. When comparing two code sequences one good way to rule out front-end bottlenecks (and other the issues) is to force code alignment. This pass adds a flag that forces the alignment of all of the basic blocks in the program. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179353 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-11Fix for wrong instcombine on vector insert/extractBenjamin Kramer
When trying to collapse sequences of insertelement/extractelement instructions into single shuffle instructions, there is one specific case where the Instruction Combiner wrongly updates the resulting Mask of shuffle indexes. The problem is in function CollectShuffleElments. If we have a sequence of insert/extract element instructions like the one below: %tmp1 = extractelement <4 x float> %LHS, i32 0 %tmp2 = insertelement <4 x float> %RHS, float %tmp1, i32 1 %tmp3 = extractelement <4 x float> %RHS, i32 2 %tmp4 = insertelement <4 x float> %tmp2, float %tmp3, i32 3 Where: . %RHS will have a mask of [4,5,6,7] . %LHS will have a mask of [0,1,2,3] The Mask of shuffle indexes is wrongly computed to [4,1,6,7] instead of [4,0,6,7]. When analyzing %tmp2 in order to compute the Mask for the resulting shuffle instruction, the algorithm forgets to update the mask index at position 1 with the index associated to the element extracted from %LHS by instruction %tmp1.
