    • [9/77] Add SCALAR_FLOAT_TYPE_MODE · b5f2d801 
      This patch adds a macro that extracts the TYPE_MODE and forcibly
converts it to a scalar_float_mode.  The forcible conversion
includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P.

This becomes important as more static type checking is added by
later patches.  It has the additional benefit of bypassing the
VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition
in TYPE_MODE; in release builds the new macro is a simple
field access.

    • [7/77] Add scalar_float_mode · e386a52f 
      This patch adds a scalar_float_mode class, which wraps a mode enum
that is known to satisfy SCALAR_FLOAT_MODE_P.  Things like "SFmode"
now give a scalar_float_mode object instead of a machine_mode.
This in turn needs a change to the real.h format_helper, so that
it can accept both machine_modes and scalar_float_modes.

    • [6/77] Make GET_MODE_WIDER return an opt_mode · 490d0f6c 
      GET_MODE_WIDER previously returned VOIDmode if no wider mode existed.
That would cause problems with stricter mode classes, since VOIDmode
isn't for example a valid scalar integer or floating-point mode.
This patch instead makes it return a new opt_mode<T> class, which
holds either a T or nothing.

    • [4/77] Add FOR_EACH iterators for modes · c94843d2 
      The new iterators are:

- FOR_EACH_MODE_IN_CLASS: iterate over all the modes in a mode class.

- FOR_EACH_MODE_FROM: iterate over all the modes in a class,
  starting at a given mode.

- FOR_EACH_WIDER_MODE: iterate over all the modes in a class,
  starting at the next widest mode after a given mode.

- FOR_EACH_2XWIDER_MODE: same, but considering only modes that
  are two times wider than the previous mode.

- FOR_EACH_MODE_UNTIL: iterate over all the modes in a class until
  a given mode is reached.

- FOR_EACH_MODE: iterate over all the modes in a class between
  two given modes, inclusive of the first but not the second.

These help with the stronger type checking added by later patches,
since every new mode will be in the same class as the previous one.

    • [3/77] Allow machine modes to be classes · b77d1a17 
      This patch makes various changes that allow modes like SImode to be
classes rather than enums.

Firstly, it adds inline functions for all mode size properties,
with the macros being simple wrappers around them.  This is necessary
for the __builtin_constant_p trick to continue working effectively when
the mode arguments are slightly more complex (but still foldable at
compile time).

These inline functions are trivial and heavily used.  There's not much
point keeping them out-of-line at -O0: if anything it would make
debugging harder rather than easier, and it would also slow things down.
The patch therefore marks them as "always_inline", if that's available.
Later patches use this approach too.

Using inline functions means that it's no longer possible to pass
an int to GET_MODE_PRECISION etc.  The Fortran and powerpcspe-c.c
parts are needed to avoid instances of that.

The patch continues to use enums for gencondmd.c, so that more
mode comparisons are integer constant expressions when checking
for always-true or always-false conditions.  This is the only
intended use of USE_ENUM_MODES.

The patch also enforces the previous replacement of case statements
by defining modes as:

  #define FOOmode ((void) 0, E_FOOmode)

This adds no overhead but makes sure that new uses of "case FOOmode:"
don't accidentally creep in when FOOmode has no specific class associated
with it.

    • [1/77] Add an E_ prefix to mode names · 0d4a1197 
      Later patches will add wrapper types for specific classes
of mode.  E.g. SImode will be a scalar_int_mode, SFmode will be a
scalar_float_mode, etc.  This patch prepares for that change by adding
an E_ prefix to the mode enum values.  It also adds #defines that map
the unprefixed names to the prefixed names; e.g:

  #define QImode E_QImode

Later patches will change this to use things like scalar_int_mode
where appropriate.

The patch continues to use enum values to initialise static data.
This isn't necessary for correctness, but it cuts down on the amount
of load-time initialisation and shouldn't have any downsides.

The patch also changes things like:

  cmp_mode == DImode ? DFmode : DImode

to:

  cmp_mode == DImode ? E_DFmode : E_DImode

This is because DImode and DFmode will eventually be different
classes, so the original ?: wouldn't be well-formed.

	PR target/82015
	* config/rs6000/rs6000.c (rs6000_expand_binop_builtin): Insure
	that the second argument of the built-in functions to unpack
	128-bit scalar types to 64-bit values is 0 or 1.  Change to use a

	Allow 64-bit values to be in Altivec registers as well as
	traditional floating point registers.
