changing the primary datastructure from being a "std::vector<unsigned char>" to being a new TypeSet class that actually has (gasp) invariants! This changes more things than I remember, but one major innovation here is that it enforces that named input values agree in type with their output values. This also eliminates code that transparently assumes (in some cases) that SDNodeXForm input/output types are the same, because this is wrong in many case. This also eliminates a bug which caused a lot of ambiguous patterns to go undetected, where a register class would sometimes pick the first possible type, causing an ambiguous pattern to get arbitrary results. With all the recent target changes, this causes no functionality change! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98534 91177308-0d34-0410-b5e6-96231b3b80d8 |
