INIT_PATTERN_VALUE

#define INIT_PATTERN_VALUE   0xFE

Expand the IFN_DEFERRED_INIT function:
LHS = DEFERRED_INIT (SIZE of the DECL, INIT_TYPE, NAME of the DECL);

Initialize the LHS with zero/pattern according to its second argument
INIT_TYPE:
if INIT_TYPE is AUTO_INIT_ZERO, use zeroes to initialize;
if INIT_TYPE is AUTO_INIT_PATTERN, use 0xFE byte-repeatable pattern
  to initialize;
The LHS variable is initialized including paddings.
The reasons to choose 0xFE for pattern initialization are:
  1. It is a non-canonical virtual address on x86_64, and at the
     high end of the i386 kernel address space.
  2. It is a very large float value (-1.694739530317379e+38).
  3. It is also an unusual number for integers.

can_interpret_as_conditional_op_p()

bool can_interpret_as_conditional_op_p	(	gimple *	stmt,
		tree *	cond_out,
		tree_code *	code_out,
		tree(&)	ops[3],
		tree *	else_out,
		tree *	len,
		tree *	bias )

Return true if STMT can be interpreted as a conditional tree code
operation of the form:

  LHS = COND ? OP (RHS1, ...) : ELSE;

operating elementwise if the operands are vectors.  This includes
the case of an all-true COND, so that the operation always happens.

There is an alternative approach to interpret the STMT when the operands
are vectors which is the operation predicated by both conditional mask
and loop control length, the equivalent C code:

  for (int i = 0; i < NUNTIS; i++)
   {
     if (i < LEN + BIAS && COND[i])
       LHS[i] = A[i] CODE B[i];
     else
       LHS[i] = ELSE[i];
   }

When returning true, set:

- *COND_OUT to the condition COND, or to NULL_TREE if the condition
  is known to be all-true
- *CODE_OUT to the tree code
- OPS[I] to operand I of *CODE_OUT
- *ELSE_OUT to the fallback value ELSE, or to NULL_TREE if the
  condition is known to be all true.
- *LEN to the len argument if it COND_LEN_* operations or to NULL_TREE.
- *BIAS to the bias argument if it COND_LEN_* operations or to NULL_TREE.

get_conditional_internal_fn() [1/2]

internal_fn get_conditional_internal_fn

(

internal_fn

fn

)

Return a function that only performs internal function FN when a
certain condition is met and that uses a given fallback value otherwise.
In other words, the returned function FN' is such that:

  LHS = FN' (COND, A1, ... An, ELSE)

is equivalent to the C expression:

  LHS = COND ? FN (A1, ..., An) : ELSE;

operating elementwise if the operands are vectors.

Return IFN_LAST if no such function exists.   

References CASE, FOR_EACH_COND_FN_PAIR, and IFN_LAST.

get_conditional_internal_fn() [2/2]

internal_fn get_conditional_internal_fn

(

tree_code

code

)

Return a function that only performs CODE when a certain condition is met
and that uses a given fallback value otherwise.  For example, if CODE is
a binary operation associated with conditional function FN:

  LHS = FN (COND, A, B, ELSE)

is equivalent to the C expression:

  LHS = COND ? A CODE B : ELSE;

operating elementwise if the operands are vectors.

Return IFN_LAST if no such function exists.   

References CASE, separate_ops::code, FOR_EACH_CODE_MAPPING, and IFN_LAST.

get_conditional_len_internal_fn()

internal_fn get_conditional_len_internal_fn

(

tree_code

code

)

Like get_conditional_internal_fn, but return a function that
  additionally restricts the operation to the leading elements
  of a vector.  The number of elements to process is given by a length
  and bias pair, as for IFN_LOAD_LEN.  The values of the remaining
  elements are taken from the fallback ("else") argument.

  For example, if CODE is a binary operation associated with FN:

    LHS = FN (COND, A, B, ELSE, LEN, BIAS)

  is equivalent to the C code:

    for (int i = 0; i < NUNITS; i++)
     {
       if (i < LEN + BIAS && COND[i])
         LHS[i] = A[i] CODE B[i];
       else
         LHS[i] = ELSE[i];
