The handling of bitfield references in expand_expr_real_1 includes:
machine_mode ext_mode = mode;
if (ext_mode == BLKmode
&& ! (target != 0 && MEM_P (op0)
&& MEM_P (target)
&& multiple_p (bitpos, BITS_PER_UNIT)))
ext_mode = int_mode_for_size (bitsize, 1).else_blk ();
if (ext_mode == BLKmode)
{
[...]
gcc_assert (MEM_P (op0)
Here "mode" is the TYPE_MODE of the result, so when mode == BLKmode,
the target must be a MEM if nonnull, since no other rtl objects can
have BLKmode. But there's no guarantee that the source value op0 is also
BLKmode and thus also a MEM: we can reach the assert for any source if
the bitsize being extracted is larger than the largest integer mode
(or larger than MAX_FIXED_MODE_SIZE).
This triggered for SVE with -msve-vector-bits=512, where we could
sometimes try to extract a BLKmode value from a 512-bit vector,
and where int_mode_for_size would rightly fail for large bitsizes.
The patch reuses the existing:
/* Otherwise, if this is a constant or the object is not in memory
and need be, put it there. */
else if (CONSTANT_P (op0) || (!MEM_P (op0) && must_force_mem))
{
memloc = assign_temp (TREE_TYPE (tem), 1, 1);
emit_move_insn (memloc, op0);
op0 = memloc;
clear_mem_expr = true;
}
to handle this case.

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.
2018-05-30 Richard Sandiford <richard.sandiford@linaro.org>
gcc/
* alias.c (adjust_offset_for_component_ref): Use poly_int_tree_p

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.

This PR is about a case in which we VIEW_CONVERT a variable-sized
unaligned record:
<record_type 0x7ffff6d92888 check_displace_generation__T245b sizes-gimplified type_7 BLK
size <var_decl 0x7ffff6846510 D.3499 ...>
unit-size <var_decl 0x7ffff68465a0 D.3500 ...>
align:8 ...>
to an aligned 32-bit integer. The strict-alignment handling of
this case creates an aligned temporary slot, moves the operand
into the slot in the operand's original mode, then accesses the
slot in the more-aligned result mode.
Previously the size of the temporary slot was calculated using:
HOST_WIDE_INT temp_size
= MAX (int_size_in_bytes (inner_type),
(HOST_WIDE_INT) GET_MODE_SIZE (mode));
int_size_in_bytes would return -1 for the variable-length type,
so we'd use the size of the result mode for the slot. r256152 replaced
int_size_in_bytes with tree_to_poly_uint64, which triggered an ICE.
If op0 has BLKmode we do a block copy of GET_MODE_SIZE (mode) bytes
and then convert the slot to "mode":
poly_uint64 mode_size = GET_MODE_SIZE (mode);
...
if (GET_MODE (op0) == BLKmode)
{
rtx size_rtx = gen_int_mode (mode_size, Pmode);
emit_block_move (new_with_op0_mode, op0, size_rtx,
(modifier == EXPAND_STACK_PARM
? BLOCK_OP_CALL_PARM
: BLOCK_OP_NORMAL));
}
else
...
op0 = new_rtx;
}
}
op0 = adjust_address (op0, mode, 0);
so I think in that case just the size of "mode" is enough, even if op0
is a fixed-size type. For non-BLKmode op0 we first move in op0's mode
and then convert the slot to "mode":
emit_move_insn (new_with_op0_mode, op0);
op0 = new_rtx;
}
}
op0 = adjust_address (op0, mode, 0);
so I think we want the maximum of the two mode sizes in that case.

This patch adds a new mode class to represent vectors of booleans.
GET_MODE_BITSIZE (m) / GET_MODE_NUNITS (m) determines the number
of bits that are used to represent each boolean; this can be 1
for a fully-packed representation or greater than 1 for an unpacked
representation. In the latter case, the value of bits other than
the lowest is not significant.
These are used by the SVE port to represent predicates.

This patch makes the CONCAT handing in expand_assignment cope with
polynomial mode sizes. The mode of the CONCAT must be complex,
so we can base the tests on the sizes of the real and imaginary

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.

PUSH_ROUNDING is difficult to convert to a hook since there is still
a lot of conditional code based on it. It isn't clear that a direct
conversion with checks for null hooks is the right thing to do.
Rather than untangle that, this patch converts all implementations
that do something to out-of-line functions that have the same
interface as a hook would have. This should at least help towards
any future hook conversion.

The new assert in add_args_size_note triggered for gcc.dg/tls/opt-3.c
and others on m68k. This looks like a pre-existing bug: if we pushed
a value that needs a call to something like __tls_get_addr, we ended
up with two different REG_ARGS_SIZE notes on the same instruction.
It seems to be OK for emit_single_push_insn to push something that
needs a call to __tls_get_addr:
/* We have to allow non-call_pop patterns for the case
of emit_single_push_insn of a TLS address. */
if (GET_CODE (pat) != PARALLEL)
return 0;
so I think the bug is in the way this is handled rather than the fact
that it occurs at all.
If we're pushing a value X that needs a call C to calculate, we'll
add REG_ARGS_SIZE notes to the pushes and pops for C as part of the
call sequence. Then emit_single_push_insn calls fixup_args_size_notes
on the whole push sequence (the calculation of X, including C,
and the push of X itself). This is where the double notes came from.
But emit_single_push_insn_1 adjusted stack_pointer_delta *before* the
push, so the notes added for C were relative to the situation after
the future push of X rather than before it.
Presumably this didn't matter in practice because the note added
second tended to trump the note added first. But code is allowed to
walk REG_NOTES without having to disregard secondary notes.

One of the changes needed for variable-length VEC_PERM_EXPRs -- and for
long fixed-length VEC_PERM_EXPRs -- is the ability to use constant
selectors that wouldn't fit in the vectors being permuted. E.g. a
permute on two V256QIs can't be done using a V256QI selector.
At the moment constant permutes use two interfaces:
targetm.vectorizer.vec_perm_const_ok for testing whether a permute is
valid and the vec_perm_const optab for actually emitting the permute.
The former gets passed a vec<> selector and the latter an rtx selector.
Most ports share a lot of code between the hook and the optab, with a
wrapper function for each interface.
We could try to keep that interface and require ports to define wider
vector modes that could be attached to the CONST_VECTOR (e.g. V256HI or
V256SI in the example above). But building a CONST_VECTOR rtx seems a bit
pointless here, since the expand code only creates the CONST_VECTOR in
order to call the optab, and the first thing the target does is take
the CONST_VECTOR apart again.
The easiest approach therefore seemed to be to remove the optab and
reuse the target hook to emit the code. One potential drawback is that
it's no longer possible to use match_operand predicates to force
operands into the required form, but in practice all targets want
register operands anyway.
The patch also changes vec_perm_indices into a class that provides
some simple routines for handling permutations. A later patch will
flesh this out and get rid of auto_vec_perm_indices, but I didn't
want to do all that in this patch and make it more complicated than
it already is.

This patch changes SUBREG_BYTE from an int to a poly_int.
Since valid SUBREG_BYTEs must be contained within the mode of the
SUBREG_REG, the required range is the same as for GET_MODE_SIZE,
i.e. unsigned short. The patch therefore uses poly_uint16(_pod)
for the SUBREG_BYTE.
Using poly_uint16_pod rtx fields requires a new field code ('p').
Since there are no other uses of 'p' besides SUBREG_BYTE, the patch
doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE
instead.
The patch doesn't bother implementing 'p' support for legacy
define_peepholes, since none of the remaining ones have subregs
in their patterns.
As it happened, the rtl documentation used SUBREG as an example of a
code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1).
Since there's no direct replacement for XINT, and since people should
never use it even if there were, the patch changes the example to use
INT_LIST instead.
The patch also changes subreg-related helper functions so that they too
take and return polynomial offsets. This makes the patch quite big, but
it's mostly mechanical. The patch generally sticks to existing choices
wrt signedness.

This patch adds a tree representation for poly_ints. Unlike the
rtx version, the coefficients are INTEGER_CSTs rather than plain
integers, so that we can easily access them as poly_widest_ints
and poly_offset_ints.
The patch also adjusts some places that previously
relied on "constant" meaning "INTEGER_CST". It also makes
sure that the TYPE_SIZE agrees with the TYPE_SIZE_UNIT for

This patch adds an rtl representation of poly_int values.
There were three possible ways of doing this:
(1) Add a new rtl code for the poly_ints themselves and store the
coefficients as trailing wide_ints. This would give constants like:
(const_poly_int [c0 c1 ... cn])
The runtime value would be:
c0 + c1 * x1 + ... + cn * xn
(2) Like (1), but use rtxes for the coefficients. This would give
constants like:
(const_poly_int [(const_int c0)
(const_int c1)
...
(const_int cn)])
although the coefficients could be const_wide_ints instead
of const_ints where appropriate.
(3) Add a new rtl code for the polynomial indeterminates,
then use them in const wrappers. A constant like c0 + c1 * x1
would then look like:
(const:M (plus:M (mult:M (const_param:M x1)
(const_int c1))
(const_int c0)))
There didn't seem to be that much to choose between them. The main
advantage of (1) is that it's a more efficient representation and
that we can refer to the cofficients directly as wide_int_storage.

This patch adds VEC_DUPLICATE_EXPR for when CONSTRUCTOR would be used
