This is v6 of the patch, as posted to:
https://gcc.gnu.org/ml/gcc-patches/2018-12/msg01331.html
The C++ frontend gained various location wrapper nodes in r256448 (GCC 8).
That patch:
https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00799.html
added wrapper nodes around all nodes with !CAN_HAVE_LOCATION_P for:
* arguments at callsites, and for
* typeid, alignof, sizeof, and offsetof.
This is a followup to that patch, adding many more location wrappers
to the C++ frontend. It adds location wrappers for nodes with
!CAN_HAVE_LOCATION_P to:
* all literal nodes (in cp_parser_primary_expression)
* all id-expression nodes (in finish_id_expression), except within a
decltype.
* all mem-initializer nodes within a mem-initializer-list
(in cp_parser_mem_initializer)
However, the patch also adds some suppressions: regions in the parser
for which wrapper nodes will not be created:
* within a template-parameter-list or template-argument-list (in
cp_parser_template_parameter_list and cp_parser_template_argument_list
respectively), to avoid encoding the spelling location of the nodes
in types. For example, "array<10>" and "array<10>" are the same type,
despite the fact that the two different "10" tokens are spelled in
different locations in the source.
* within a gnu-style attribute (none of are handlers are set up to cope
with location wrappers yet)
* within various OpenMP clauses
The patch enables various improvements to locations for bad
initializations, for -Wchar-subscripts, and enables various other
improvements in the followup patch.
For example, given the followup buggy mem-initializer:
class X {
X() : bad(42),
good(42)
{ }
void* bad;
int good;
};
previously, our diagnostic was on the final close parenthesis of the
mem-initializer-list, leaving it unclear where the problem is:
t.cc: In constructor 'X::X()':
t.cc:3:16: error: invalid conversion from 'int' to 'void*' [-fpermissive]
3 | good(42)
| ^
| |
| int
whereas with the patch we highlight which expression is bogus:
t.cc: In constructor 'X::X()':
t.cc:2:13: error: invalid conversion from 'int' to 'void*' [-fpermissive]
2 | X() : bad(42),
| ^~
| |
| int
Similarly, the diagnostic for this bogus initialization:
i.cc:1:44: error: initializer-string for array of chars is too long [-fpermissive]
1 | char test[3][4] = { "ok", "too long", "ok" };
| ^
is improved by the patch so that it indicates which string is too long:
i.cc:1:27: error: initializer-string for array of chars is too long [-fpermissive]
1 | char test[3][4] = { "ok", "too long", "ok" };
| ^~~~~~~~~~

This patch uses IFN_COND_* to vectorise conditionally-executed,
potentially-trapping arithmetic, such as most floating-point
ops with -ftrapping-math. E.g.:
if (cond) { ... x = a + b; ... }
becomes:
...
x = .COND_ADD (cond, a, b, else_value);
...
When this transformation is done on its own, the value of x for
!cond isn't important, so else_value is simply the target's
preferred_else_value (i.e. the value it can handle the most
efficiently).
However, the patch also looks for the equivalent of:
y = cond ? x : c;
in which the "then" value is the result of the conditionally-executed
operation and the "else" value "c" is some value that is available at x.
In that case we can instead use:
x = .COND_ADD (cond, a, b, c);
and replace uses of y with uses of x.
The patch also looks for:
y = !cond ? c : x;
which can be transformed in the same way. This involved adding a new
utility function inverse_conditions_p, which was already open-coded
in a more limited way in match.pd.

This patch generalises various places that used hwi tree accessors so
that they can handle poly_ints instead. In many cases these changes
are by inspection rather than because something had shown them to be
necessary.
I think the alias.c part is a minor bug fix: previously we used
fits_uhwi_p for a signed HOST_WIDE_INT (which the caller does
treat as signed rather than unsigned). We also checked whether
each individual offset overflowed but didn't check whether the
sum did.

There are four optabs for various forms of fused multiply-add:
fma, fms, fnma and fnms. Of these, only fma had a direct gimple
representation. For the other three we relied on special pattern-
matching during expand, although tree-ssa-math-opts.c did have
some code to try to second-guess what expand would do.
This patch removes the old FMA_EXPR representation of fma and
introduces four new internal functions, one for each optab.
IFN_FMA is tied to BUILT_IN_FMA* while the other three are
independent directly-mapped internal functions. It's then
possible to do the pattern-matching in match.pd and
tree-ssa-math-opts.c (via folding) can select the exact
FMA-based operation.
The BRIG & HSA parts are a best guess, but seem relatively simple.

The first BIT_FIELD_REF folding pattern assumed without checking that
operands satisfy tree_fits_uhwi_p. The second pattern does check this:
/* On constants we can use native encode/interpret to constant
fold (nearly) all BIT_FIELD_REFs. */
if (CONSTANT_CLASS_P (arg0)
&& can_native_interpret_type_p (type)
&& BITS_PER_UNIT == 8
&& tree_fits_uhwi_p (op1)
&& tree_fits_uhwi_p (op2))

This patch changes TYPE_VECTOR_SUBPARTS to a poly_uint64. The value is
encoded in the 10-bit precision field and was previously always stored
as a simple log2 value. The challenge was to use this 10 bits to
encode the number of elements in variable-length vectors, so that
we didn't need to increase the size of the tree.
In practice the number of vector elements should always have the form
N + N * X (where X is the runtime value), and as for constant-length
vectors, N must be a power of 2 (even though X itself might not be).
The patch therefore uses the low 8 bits to encode log2(N) and bit
8 to select between constant-length and variable-length vectors.
Targets without variable-length vectors continue to use the old scheme.
A new valid_vector_subparts_p function tests whether a given number
of elements can be encoded. This is false for the vector modes that
represent an LD3 or ST3 vector triple (which we want to treat as arrays
of vectors rather than single vectors).
Most of the patch is mechanical; previous patches handled the changes
that weren't entirely straightforward.

This patch changes GET_MODE_NUNITS from unsigned char
to poly_uint16, although it remains a macro when compiling
target code with NUM_POLY_INT_COEFFS == 1.
We can handle permuted loads and stores for variable nunits if
the number of statements is a power of 2, but not otherwise.
The to_constant call in make_vector_type goes away in a later patch.

This patch changes the number of elements in a vector being built
by a vector_builder from unsigned int to poly_uint64. The case
in which it isn't a constant is the one that motivated adding
the vector encoding in the first place.

This patch makes fold_indirect_ref_1 handle polynomial offsets in
a POINTER_PLUS_EXPR. The specific reason for doing this now is
to handle:
(tree_to_uhwi (part_width) / BITS_PER_UNIT
* TYPE_VECTOR_SUBPARTS (op00type));
when TYPE_VECTOR_SUBPARTS becomes a poly_int.
