Build a variable-length vector in which the elements in ELTS are repeated
to a fill NRESULTS vectors of type VECTOR_TYPE. Store the vectors in
RESULTS and add any new instructions to SEQ.
The approach we use is:
(1) Find a vector mode VM with integer elements of mode IM.
(2) Replace ELTS[0:NELTS] with ELTS'[0:NELTS'], where each element of
ELTS' has mode IM. This involves creating NELTS' VIEW_CONVERT_EXPRs
from small vectors to IM.
(3) Duplicate each ELTS'[I] into a vector of mode VM.
(4) Use a tree of interleaving VEC_PERM_EXPRs to create VMs with the
correct byte contents.
(5) Use VIEW_CONVERT_EXPR to cast the final VMs to the required type.
We try to find the largest IM for which this sequence works, in order
to cut down on the number of interleaves.

Such NODES are then directly converted into LOADS themselves. The nodes are CSEd using BST_MAP.

Verify if the scalar stmts STMTS are isomorphic, require data permutation or are of unsupported types of operation. Return true if they are, otherwise return false and indicate in *MATCHES which stmts are not isomorphic to the first one. If MATCHES[0] is false then this indicates the comparison could not be carried out or the stmts will never be vectorized by SLP. Note COND_EXPR is possibly isomorphic to another one after swapping its operands. Set SWAP[i] to 1 if stmt I is COND_EXPR and isomorphic to the first stmt by swapping the two operands of comparison; set SWAP[i] to 2 if stmt I is isormorphic to the first stmt by inverting the code of comparison. Take A1 >= B1 ? X1 : Y1 as an exmple, it can be swapped to (B1 <= A1 ? X1 : Y1); or be inverted to (A1 < B1) ? Y1 : X1.

Get the defs for the rhs of STMT (collect them in OPRNDS_INFO), check that they are of a valid type and that they match the defs of the first stmt of the SLP group (stored in OPRNDS_INFO). This function tries to match stmts by swapping operands of STMTS[STMT_NUM] when possible. Non-zero SWAP indicates swap is required for cond_expr stmts. Specifically, SWAP is 1 if STMT is cond and operands of comparison need to be swapped; SWAP is 2 if STMT is cond and code of comparison needs to be inverted. If there was a fatal error return -1; if the error could be corrected by swapping operands of father node of this one, return 1; if everything is ok return 0.

The special index -1 is the first operand of an embedded comparison and the special index -2 is the second operand of an embedded comparison.

◆ vectorizable_slp_permutation_1()
|
static |
Subroutine of vectorizable_slp_permutation. Check whether the target can perform permutation PERM on the (1 or 2) input nodes in CHILDREN. If GSI is nonnull, emit the permutation there. When GSI is null, the only purpose of NODE is to give properties of the result, such as the vector type and number of SLP lanes. The node does not need to be a VEC_PERM_EXPR. If the target supports the operation, return the number of individual VEC_PERM_EXPRs needed, otherwise return -1. Print information to the dump file if DUMP_P is true.
