2008-07-18Revert 53729, after waking up in the middle ofDuncan Sands
the night realising that it was wrong :) I think the reason the same type was being used for the shufflevec of indices as for the actual indices is so that if one of them needs splitting then so does the other. After my patch it might be that the indices need splitting but not the rest, yet there is no good way of handling that. I think the right solution is to not have the shufflevec be an operand at all: just have it be the list of numbers it actually is, stored as extra info in the node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53768 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-17Use a legal type for elements of the vector_shuffleDuncan Sands
mask. These are just indices into the shuffled vector so their type is unrelated to the type of the shuffled elements (which is what was being used before). This fixes vec_shuffle-11.ll when using LegalizeTypes. What seems to have happened is that Dan's recent change r53687, which corrected the result type of the shuffle, somehow caused LegalizeTypes to notice that the mask operand was a BUILD_VECTOR with a legal type but elements of an illegal type (i64). LegalizeTypes legalized this by introducing a new BUILD_VECTOR of i32 and bitcasting it to the old type. But the mask operand is not supposed to be a bitcast but a straight BUILD_VECTOR of constants, causing a crash. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53729 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-17Add a new function, ReplaceAllUsesOfValuesWith, which handles bulkDan Gohman
replacement of multiple values. This is slightly more efficient than doing multiple ReplaceAllUsesOfValueWith calls, and theoretically could be optimized even further. However, an important property of this new function is that it handles the case where the source value set and destination value set overlap. This makes it feasible for isel to use SelectNodeTo in many very common cases, which is advantageous because SelectNodeTo avoids a temporary node and it doesn't require CSEMap updates for users of values that don't change position. Revamp MorphNodeTo, which is what does all the work of SelectNodeTo, to handle operand lists more efficiently, and to correctly handle a number of corner cases to which its new wider use exposes it. This commit also includes a change to the encoding of post-isel opcodes in SDNodes; now instead of being sandwiched between the target-independent pre-isel opcodes and the target-dependent pre-isel opcodes, post-isel opcodes are now represented as negative values. This makes it possible to test if an opcode is pre-isel or post-isel without having to know the size of the current target's post-isel instruction set. These changes speed up llc overall by 3% and reduce memory usage by 10% on the InstructionCombining.cpp testcase with -fast and -regalloc=local. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53728 91177308-0d34-0410-b5e6-96231b3b80d8
