calculatePreExtendType()

static EVT calculatePreExtendType ( SDValue  Extend )

static

Calculates what the pre-extend type is, based on the extension operation node provided by Extend.

In the case that Extend is a SIGN_EXTEND or a ZERO_EXTEND, the pre-extend type is pulled directly from the operand, while other extend operations need a bit more inspection to get this information.

Parameters

Extend

The SDNode from the DAG that represents the extend operation

Returns

The type representing the Extend source type, or MVT::Other if no valid type can be determined

canEmitConjunction()

static bool canEmitConjunction ( const SDValue  Val, bool &  CanNegate, bool &  MustBeFirst, bool  WillNegate, unsigned  Depth = 0  )

static

Returns true if Val is a tree of AND/OR/SETCC operations that can be expressed as a conjunction.

See CMP;CCMP matching.

Parameters

CanNegate	Set to true if we can negate the whole sub-tree just by changing the conditions on the SETCC tests. (this means we can call emitConjunctionRec() with Negate==true on this sub-tree)
MustBeFirst	Set to true if this subtree needs to be negated and we cannot do the negation naturally. We are required to emit the subtree first in this case.
WillNegate	Is true if are called when the result of this subexpression must be negated. This happens when the outer expression is an OR. We can use this fact to know that we have a double negation (or (or ...) ...) that can be implemented for free.

A counterexample is "or (and A B) (and C D)" which translates to not (and (not (and (not A) (not B))) (not (and (not C) (not D)))), we can only implement 1 of the inner (not) operations, but not both! Create a conditional comparison; Use CCMP, CCMN or FCCMP as appropriate.

If the operand is a bitwise AND with a constant RHS, and the shift has a constant RHS and is the only use, we can pull it out of the shift, i.e.

(shl (and X, C1), C2) -> (and (shl X, C2), (shl C1, C2))

static SDValue replaceSplatVectorStore ( SelectionDAG &  DAG, StoreSDNode &  St  )

Replace a splat of a scalar to a vector store by scalar stores of the scalar value.

The load store optimizer pass will merge them to store pair stores. This has better performance than a splat of the scalar followed by a split vector store. Even if the stores are not merged it is four stores vs a dup, followed by an ext.b and two stores.

replaceZeroVectorStore()

static SDValue replaceZeroVectorStore ( SelectionDAG &  DAG, StoreSDNode &  St  )

Replace a splat of zeros to a vector store by scalar stores of WZR/XZR.

The load store optimizer pass will merge them to store pair stores. This should be better than a movi to create the vector zero followed by a vector store if the zero constant is not re-used, since one instructions and one register live range will be removed.

For example, the final generated code should be:

stp xzr, xzr, [x0]

instead of:

movi v0.2d, #0 str q0, [x0]
