[FPEnv] Constrained FCmp intrinsics

Browse Source 
This adds support for constrained floating-point comparison intrinsics.

Specifically, we add:

      declare <ty2>
      @llvm.experimental.constrained.fcmp(<type> <op1>, <type> <op2>,
                                          metadata <condition code>,
                                          metadata <exception behavior>)
      declare <ty2>
      @llvm.experimental.constrained.fcmps(<type> <op1>, <type> <op2>,
                                           metadata <condition code>,
                                           metadata <exception behavior>)

The first variant implements an IEEE "quiet" comparison (i.e. we only
get an invalid FP exception if either argument is a SNaN), while the
second variant implements an IEEE "signaling" comparison (i.e. we get
an invalid FP exception if either argument is any NaN).

The condition code is implemented as a metadata string.  The same set
of predicates as for the fcmp instruction is supported (except for the
"true" and "false" predicates).

These new intrinsics are mapped by SelectionDAG codegen onto two new
ISD opcodes, ISD::STRICT_FSETCC and ISD::STRICT_FSETCCS, again
representing quiet vs. signaling comparison operations.  Otherwise
those nodes look like SETCC nodes, with an additional chain argument
and result as usual for strict FP nodes.  The patch includes support
for the common legalization operations for those nodes.

The patch also includes full SystemZ back-end support for the new
ISD nodes, mapping them to all available SystemZ instruction to
fully implement strict semantics (scalar and vector).

'``llvm.experimental.constrained.fcmp``' and '``llvm.experimental.constrained.fcmps``' Intrinsics
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Syntax:
"""""""
::
declare <ty2>
@llvm.experimental.constrained.fcmp(<type> <op1>, <type> <op2>,
metadata <condition code>,
metadata <exception behavior>)
declare <ty2>
@llvm.experimental.constrained.fcmps(<type> <op1>, <type> <op2>,
metadata <condition code>,
metadata <exception behavior>)
Overview:
"""""""""
The '``llvm.experimental.constrained.fcmp``' and
'``llvm.experimental.constrained.fcmps``' intrinsics return a boolean
value or vector of boolean values based on comparison of its operands.
If the operands are floating-point scalars, then the result type is a
boolean (:ref:`i1 <t_integer>`).
If the operands are floating-point vectors, then the result type is a
vector of boolean with the same number of elements as the operands being
compared.
The '``llvm.experimental.constrained.fcmp``' intrinsic performs a quiet
comparison operation while the '``llvm.experimental.constrained.fcmps``'
intrinsic performs a signaling comparison operation.
Arguments:
""""""""""
The first two arguments to the '``llvm.experimental.constrained.fcmp``'
and '``llvm.experimental.constrained.fcmps``' intrinsics must be
:ref:`floating-point <t_floating>` or :ref:`vector <t_vector>`
of floating-point values. Both arguments must have identical types.
The third argument is the condition code indicating the kind of comparison
to perform. It must be a metadata string with one of the following values:
- "``oeq``": ordered and equal
- "``ogt``": ordered and greater than
- "``oge``": ordered and greater than or equal
- "``olt``": ordered and less than
- "``ole``": ordered and less than or equal
- "``one``": ordered and not equal
- "``ord``": ordered (no nans)
- "``ueq``": unordered or equal
- "``ugt``": unordered or greater than
- "``uge``": unordered or greater than or equal
- "``ult``": unordered or less than
- "``ule``": unordered or less than or equal
- "``une``": unordered or not equal
- "``uno``": unordered (either nans)
*Ordered* means that neither operand is a NAN while *unordered* means
that either operand may be a NAN.
The fourth argument specifies the exception behavior as described above.
Semantics:
""""""""""
``op1`` and ``op2`` are compared according to the condition code given
as the third argument. If the operands are vectors, then the
vectors are compared element by element. Each comparison performed
always yields an :ref:`i1 <t_integer>` result, as follows:
- "``oeq``": yields ``true`` if both operands are not a NAN and ``op1``
is equal to ``op2``.
- "``ogt``": yields ``true`` if both operands are not a NAN and ``op1``
is greater than ``op2``.
- "``oge``": yields ``true`` if both operands are not a NAN and ``op1``
is greater than or equal to ``op2``.
- "``olt``": yields ``true`` if both operands are not a NAN and ``op1``
is less than ``op2``.
- "``ole``": yields ``true`` if both operands are not a NAN and ``op1``
is less than or equal to ``op2``.
- "``one``": yields ``true`` if both operands are not a NAN and ``op1``
is not equal to ``op2``.
- "``ord``": yields ``true`` if both operands are not a NAN.
- "``ueq``": yields ``true`` if either operand is a NAN or ``op1`` is
equal to ``op2``.
- "``ugt``": yields ``true`` if either operand is a NAN or ``op1`` is
greater than ``op2``.
- "``uge``": yields ``true`` if either operand is a NAN or ``op1`` is
greater than or equal to ``op2``.
- "``ult``": yields ``true`` if either operand is a NAN or ``op1`` is
less than ``op2``.
- "``ule``": yields ``true`` if either operand is a NAN or ``op1`` is
less than or equal to ``op2``.
- "``une``": yields ``true`` if either operand is a NAN or ``op1`` is
not equal to ``op2``.
- "``uno``": yields ``true`` if either operand is a NAN.
The quiet comparison operation performed by
'``llvm.experimental.constrained.fcmp``' will only raise an exception
if either operand is a SNAN. The signaling comparison operation
performed by '``llvm.experimental.constrained.fcmps``' will raise an
exception if either operand is a NAN (QNAN or SNAN).
