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.

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.

◆ getOrderedReductionCost()

InstructionCost llvm::BasicTTIImplBase< T >::getOrderedReductionCost ( unsigned Opcode,
VectorType * Ty,

inline

Try to calculate the cost of performing strict (in-order) reductions, which involves doing a sequence of floating point additions in lane order, starting with an initial value.

For example, consider a scalar initial value 'InitVal' of type float and a vector of type <4 x float>:

Vector = <float v0, float v1, float v2, float v3>

add1 = InitVal + v0 add2 = add1 + v1 add3 = add2 + v2 add4 = add3 + v3

As a simple estimate we can say the cost of such a reduction is 4 times the cost of a scalar FP addition. We can only estimate the costs for fixed-width vectors here because for scalable vectors we do not know the runtime number of operations.

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

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

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.

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