This patch protects various uses of DECL_FUNCTION_CODE that didn't
obviously check for BUILT_IN_NORMAL first (either directly or in callers).
They could therefore trigger for functions that either aren't built-ins
or are a different kind of built-in.
Also, the patch removes a redundant GIMPLE_CALL check from
optimize_stdarg_builtin, since it gave the impression that the stmt
was less well checked than it actually is.

As Jakub pointed out, if we narrow a plus, minus or mult operation based
on the number of bits that consumers need, we have to convert a signed
operation to an unsigned one in order to avoid new undefined behaviour.
This patch does that and generalises vect_convert_input and
vect_recog_over_widening_pattern to cope with the extra casts.
(The changes to both functions are covered by existing tests.)

This long patch only does one simple thing, adds an explicit function
parameter to predicates stmt_could_throw_p, stmt_can_throw_external
and stmt_can_throw_internal.
My motivation was ability to use stmt_can_throw_external in IPA
analysis phase without the need to push cfun. As I have discovered,
we were already doing that in cgraph.c, which this patch avoids as
well. In the process, I had to add a struct function parameter to
stmt_could_throw_p and decided to also change the interface of
stmt_can_throw_internal just for the sake of some minimal consistency.
In the process I have discovered that calling method
cgraph_node::create_version_clone_with_body (used by ipa-split,
ipa-sra, OMP simd and multiple_target) leads to calls of
stmt_can_throw_external with NULL cfun. I have worked around this by
making stmt_can_throw_external and stmt_could_throw_p gracefully
accept NULL and just be pessimistic in that case. The problem with
fixing this in a better way is that struct function for the clone is
created after cloning edges where we attempt to push the yet not
existing cfun, and moving it before would require a bit of surgery in
tree-inline.c. A slightly hackish but simpler fix might be to
explicitely pass the "old" function to symbol_table::create_edge
because it should be just as good at that moment. In any event, that
is a topic for another patch.
I believe that currently we incorrectly use cfun in
maybe_clean_eh_stmt_fn and maybe_duplicate_eh_stmt_fn, both in
tree-eh.c, and so I have fixed these cases too. The bulk of other
changes is just mechanical adding of cfun to all users.
Bootstrapped and tested on x86_64-linux (also with extra NULLing and
restoring cfun to double check it is not used in a place I missed), OK
for trunk?
Thanks,
Martin

As promised at Cauldron, this patch uses %T and %G with dump_printf and
dump_printf_loc calls to eliminate calls to
dump_generic_expr (MSG_*, arg, TDF_SLIM) (via %T)
and
dump_gimple_stmt (MSG_*, TDF_SLIM, stmt, 0) (via %G)
throughout the middle-end, simplifying numerous dump callsites.
A few calls to these functions didn't match the above pattern; I didn't

This patch makes dr_aux link back to both the scalar data_reference
and the containing stmt_vec_info, so that it becomes a suitable key
for a vectorisable reference.
The data_reference link is just STMT_VINFO_DATA_REF, moved here
from _stmt_vec_info. The stmt pointer is a new field and always
tracks the current stmt_vec_info for the reference (which might
be a pattern stmt or the original stmt).
The patch also makes the dr_aux in this current stmt be the one
that counts, rather than have the information stay with the DR_STMT.
A new macro (STMT_VINFO_DR_INFO) gives this information for a given
stmt_info.
In future we could make dr_aux a separate structure, which would
be useful if we want to support multiple data references per stmt.
That seems too much of a diversion for this series though.

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.

The PR85694 series removed the only cases in which a pattern recogniser
could attach patterns to more than one statement. I think it would be
better to avoid adding any new instances of that, since it interferes
with the normal matching order.
This patch therefore switches the interface back to passing a single
statement instead of a vector. It also gets rid of the clearing of
STMT_VINFO_RELATED_STMT on failure, since no recognisers use it now.

This patch adds detection of average instructions:
a = (((wide) b + (wide) c) >> 1);
--> a = (wide) .AVG_FLOOR (b, c);
a = (((wide) b + (wide) c + 1) >> 1);
--> a = (wide) .AVG_CEIL (b, c);
in cases where users of "a" need only the low half of the result,
making the cast to (wide) redundant. The heavy lifting was done by
earlier patches.
This showed up another problem in vectorizable_call: if the call is a
pattern definition statement rather than the main pattern statement,
the type of vectorised call might be different from the type of the
original statement.

The main over-widening patch can introduce quite a few extra casts,
and in many cases those casts simply "tap into" an intermediate
point in an existing extension. E.g. if we have:
unsigned char a;
int ax = (int) a;
and a later operation using ax is shortened to "unsigned short",
we would need:
unsigned short ax' = (unsigned short) a;
The a->ax extension requires one set of unpacks to get to unsigned
short and another set of unpacks to get to int. The first set are
then duplicated for ax'. If both ax and ax' are needed, the a->ax'
extension would end up counting twice during cost calculations.
This patch rewrites the original:
int ax = (int) a;
into a pattern:
unsigned short ax' = (unsigned short) a;
int ax = (int) ax';
so that each extension only counts once.

This patch is the main part of PR85694. The aim is to recognise at least:
signed char *a, *b, *c;
...
for (int i = 0; i < 2048; i++)
c[i] = (a[i] + b[i]) >> 1;
as an over-widening pattern, since the addition and shift can be done
on shorts rather than ints. However, it ended up being a lot more
general than that.
The current over-widening pattern detection is limited to a few simple
cases: logical ops with immediate second operands, and shifts by a
constant. These cases are enough for common pixel-format conversion
and can be detected in a peephole way.
The loop above requires two generalisations of the current code: support
for addition as well as logical ops, and support for non-constant second
operands. These are harder to detect in the same peephole way, so the
patch tries to take a more global approach.
The idea is to get information about the minimum operation width
in two ways:
(1) by using the range information attached to the SSA_NAMEs
(effectively a forward walk, since the range info is
context-independent).
(2) by back-propagating the number of output bits required by
users of the result.
As explained in the comments, there's a balance to be struck between
narrowing an individual operation and fitting in with the surrounding
code. The approach is pretty conservative: if we could narrow an
operation to N bits without changing its semantics, it's OK to do that if:
- no operations later in the chain require more than N bits; or
- all internally-defined inputs are extended from N bits or fewer,
and at least one of them is single-use.
See the comments for the rationale.
I didn't bother adding STMT_VINFO_* wrappers for the new fields
since the code seemed more readable without.

r262275 allowed pattern matching on pattern statements. Testing for
SVE on more benchmarks showed a case where this interacted badly
with 14/n.
The new over-widening detection could narrow a COND_EXPR A to another
COND_EXPR B, which mixed_size_cond could then match. This was working
as expected. However, we left B (now dead) in the pattern definition
sequence with a non-null PATTERN_DEF_SEQ. mask_conversion also
matched B, and unlike most recognisers, didn't clear PATTERN_DEF_SEQ
before adding statements to it. This meant that the statements
created by mixed_size_cond appeared in two supposedy separate
sequences, causing much confusion.
This patch removes pattern statements that are replaced by further
pattern statements. As a belt-and-braces fix, it also nullifies
PATTERN_DEF_SEQ on failure, in the same way Richard B. did recently
for RELATED_STMT.
I have patches to clean up the PATTERN_DEF_SEQ handling, but they
only apply after the complete PR85694 sequence, whereas this needs
to go in before 14/n.

vect_recog_rotate_pattern had code to prevent operations
on invariants being vectorised unnecessarily:
if (dt == vect_external_def
&& TREE_CODE (oprnd1) == SSA_NAME
&& is_a <loop_vec_info> (vinfo))
{
struct loop *loop = as_a <loop_vec_info> (vinfo)->loop;
ext_def = loop_preheader_edge (loop);
if (!SSA_NAME_IS_DEFAULT_DEF (oprnd1))
{
basic_block bb = gimple_bb (SSA_NAME_DEF_STMT (oprnd1));
if (bb == NULL
|| !dominated_by_p (CDI_DOMINATORS, ext_def->dest, bb))
ext_def = NULL;
}
}
[..]
if (ext_def)
{
basic_block new_bb
= gsi_insert_on_edge_immediate (ext_def, def_stmt);
gcc_assert (!new_bb);
}
This patch reuses the same idea for casts of invariants created
during widening optimisations.
One hitch was that vect_loop_versioning asserted that the vector loop
preheader was still empty, although the cfg transformation it's doing
should be correct either way.

This patch adds helper functions for detecting widened operations and
generalises the existing code to handle more cases.
One of the main changes is to recognise multi-stage type conversions,
which are possible even in the original IR and can also occur as a
result of earlier pattern matching (especially after the main
over-widening patch). E.g. for:
unsigned int res = 0;
for (__INTPTR_TYPE__ i = 0; i < N; ++i)
{
int av = a[i];
int bv = b[i];
short diff = av - bv;
unsigned short abs = diff < 0 ? -diff : diff;
res += abs;
}
we have:
_9 = _7 - _8;
diff_20 = (short int) _9;
_10 = (int) diff_20;
_11 = ABS_EXPR <_10>;
where the first cast establishes the sign of the promotion done
by the second cast.
vect_recog_sad_pattern didn't handle this kind of intermediate promotion
between the MINUS_EXPR and the ABS_EXPR. Sign extensions and casts from
unsigned to signed are both OK there. Unsigned promotions aren't, and
need to be rejected, but should have been folded away earlier anyway.
Also, the dot_prod and widen_sum patterns both required the promotions
to be from one signedness to the same signedness, rather than say signed
char to unsigned int. That shouldn't be necessary, since it's only the
sign of the input to the promotion that matters. Nothing requires the
narrow and wide types in a DOT_PROD_EXPR or WIDEN_SUM_EXPR to have the
same sign (and IMO that's a good thing).
Fixing these fixed an XFAIL in gcc.dg/vect/vect-widen-mult-sum.c.
vect_widened_op_tree is a bit more general than the current patch needs,
since it copes with a tree of operations rather than a single statement.
This is used by the later average-detection patch.
The patch also uses a common routine to handle both the WIDEN_MULT_EXPR
and WIDEN_LSHIFT_EXPR patterns. I hope this could be reused for other
similar operations in future.
Also, the patch means we recognise the index calculations in
vect-mult-const-pattern*.c as widening multiplications, whereas the
scan test was expecting them to be recognised as mult patterns instead.
The patch makes the tests check specifically for the multiplication we
care about.

Although the first pattern match wins in the sense that no later
function can match the *old* gimple statement, it still seems worth
letting them match the *new* gimple statements, just like we would if
the original IR had included that sequence from the outset.
This is mostly true after the later patch for PR85694, where e.g. we
could recognise:
signed char a;
int ap = (int) a;
int res = ap * 3;
as the pattern:
short ap' = (short) a;
short res = ap' * 3; // S1: definition statement
int res = (int) res; // S2: pattern statement
and then apply the mult pattern to "ap' * 3". The patch needs to
come first (without its own test cases) so that the main over-widening
patch doesn't regress anything.
