Member Function Documentation

build()

void complex_add_pattern::build ( vec_info * vinfo )

finaloverridevirtual

Perform a replacement of the detected complex add pattern with the new
instruction sequences.   

Implements vect_pattern.

matches() [1/2]

internal_fn complex_add_pattern::matches ( complex_operation_t op, slp_tree_to_load_perm_map_t * perm_cache, slp_compat_nodes_map_t * , slp_tree * node, vec< slp_tree > * ops )

static

Pattern matcher for trying to match complex addition pattern in SLP tree.

If no match is found then IFN is set to IFN_LAST.
This function matches the patterns shaped as:

c[i] = a[i] - b[i+1];
c[i+1] = a[i+1] + b[i];

If a match occurred then TRUE is returned, else FALSE.  The initial match is
expected to be in OP1 and the initial match operands in args0.
