* tree-vect-stmts.c (vectorizable_call): For j == 0 use
|
||
|
|
vargs.safe_grow (nargs) rather than vargs.create (nargs), for j != 0
|
||
|
|
remove vargs.truncate (0). Instead of vargs.quick_push store into
|
||
|
|
vargs[i]. Use vargs[i] instead of gimple_call_arg (new_stmt, i)
|
||
|
|
if j != 0.
|
||
|
|
|
||
|
|
* gcc.c-torture/compile/20240418.c: New test.
