Detailed Description

template<typename T>
class llvm::BasicTTIImplBase< T >

Base class which can be used to help build a TTI implementation.

This class provides as much implementation of the TTI interface as is possible using the target independent parts of the code generator.

In order to subclass it, your class must implement a getST() method to return the subtarget, and a getTLI() method to return the target lowering. We need these methods implemented in the derived class so that this class doesn't have to duplicate storage for them.

Try to calculate arithmetic and shuffle op costs for reduction operations.

We're assuming that reduction operation are performing the following way:

  1. Non-pairwise reduction val1 = shufflevector<n x t> val, <n x t> undef, <n x i32> <i32 n/2, i32 n/2 + 1, ..., i32 n, i32 undef, ..., i32 undef> -------------—v----------—/ -------—v---------—/ n/2 elements n/2 elements red1 = op <n x t> val, <n x t> val1 After this operation we have a vector red1 where only the first n/2 elements are meaningful, the second n/2 elements are undefined and can be dropped. All other operations are actually working with the vector of length n/2, not n, though the real vector length is still n. val2 = shufflevector<n x t> red1, <n x t> undef, <n x i32> <i32 n/4, i32 n/4 + 1, ..., i32 n/2, i32 undef, ..., i32 undef> -------------—v----------—/ -------—v---------—/ n/4 elements 3*n/4 elements red2 = op <n x t> red1, <n x t> val2 - working with the vector of length n/2, the resulting vector has length n/4 etc.
  2. Pairwise reduction: Everything is the same except for an additional shuffle operation which is used to produce operands for pairwise kind of reductions. val1 = shufflevector<n x t> val, <n x t> undef, <n x i32> <i32 0, i32 2, ..., i32 n-2, i32 undef, ..., i32 undef> ----------—v-------—/ -------—v---------—/ n/2 elements n/2 elements val2 = shufflevector<n x t> val, <n x t> undef, <n x i32> <i32 1, i32 3, ..., i32 n-1, i32 undef, ..., i32 undef> ----------—v-------—/ -------—v---------—/ n/2 elements n/2 elements red1 = op <n x t> val1, <n x t> val2 Again, the operation is performed on <n x t> vector, but the resulting vector red1 is <n/2 x t> vector.

The cost model should take into account that the actual length of the vector is reduced on each iteration.

inline

Compute a cost of the given call instruction.

Compute the cost of calling function F with return type RetTy and argument types Tys. F might be nullptr, in this case the cost of an arbitrary call with the specified signature will be returned. This is used, for instance, when we estimate call of a vector counterpart of the given function.

Parameters
FCalled function, might be nullptr.
RetTyReturn value types.
TysArgument types.
Returns
The cost of Call instruction.

Try to find the estimated number of clusters. Note that the number of clusters identified in this function could be different from the actual numbers found in lowering. This function ignore switches that are lowered with a mix of jump table / bit test / BTree. This function was initially intended to be used when estimating the cost of switch in inline cost heuristic, but it's a generic cost model to be used in other places (e.g., in loop unrolling).
