Detailed Description

This function combines all the existing pattern matchers above into one class
that shares the functionality between them.  The initial match is shared
between all complex operations.

Member Function Documentation

◆ build()

void complex_operations_pattern::build ( vec_info * )
finaloverridevirtual 
Dummy implementation of build.

Implements vect_pattern.

References gcc_unreachable.

◆ build_common()

void complex_pattern::build_common ( vec_info * vinfo)
protectedinherited 
Create a replacement pattern statement for each node in m_node and inserts
  the new statement into m_node as the new representative statement.  The old
  statement is marked as being in a pattern defined by the new statement.  The
  statement is created as call to internal function IFN with m_num_args
  arguments.

  Furthermore the new pattern is also added to the vectorization information
  structure VINFO and the old statement STMT_INFO is marked as unused while
  the new statement is marked as used and the number of SLP uses of the new
  statement is incremented.

  The newly created SLP nodes are marked as SLP only and will be dissolved
  if SLP is aborted.

  The newly created gimple call is returned and the BB remains unchanged.

  This default method is designed to only match against simple operands where
  all the input and output types are the same.
