FAIL: gcc.target/powerpc/vec-splati-runnable.c 1 blank line(s) in output
FAIL: gcc.target/powerpc/vec-splati-runnable.c (test for excess errors)
Excess errors:
rs6000_emit_xxspltidp_v2df called ...
and running the test fails. As the comment says
/* Although the instruction says the results are not defined, it does seem
to work, at least on Mambo. But no guarentees! */

this patch removes the pass to materialize all clones and instead this
is now done on demand. The motivation is to reduce lifetime of function
bodies in ltrans that should noticeably reduce memory use for highly
parallel compilations of large programs (like Martin does) or with
partitioning reduced/disabled. For cc1 with one partition the memory use
seems to go down from 4gb to cca 1.5gb (seeing from top, so this is not
particularly accurate).

Hi,
This adds support for the VSX load/store rightmost element operations.
This includes the instructions lxvrbx, lxvrhx, lxvrwx, lxvrdx,
stxvrbx, stxvrhx, stxvrwx, stxvrdx; And the builtins
vec_xl_sext() /* vector load sign extend */
vec_xl_zext() /* vector load zero extend */
vec_xst_trunc() /* vector store truncate */.
Testcase results show that the instructions added with this patch show
up at low/no optimization (-O0), with a number of those being replaced
with other load and store instructions at higher optimization levels.
For consistency I've left the tests at -O0.

corrected.

Hi
This is a sub-set of the 128-bit sign extension support patch series
that will be fully implemented in a subsequent patch from Carl.
This is a necessary pre-requisite for the vector-load/store rightmost
element patch that follows in this thread.
[v2] Refreshed and touched up per review comments.

UNSPEC_EXTENDDITI2 and UNSPEC_MTVSRD_DITI_W1 entries.

whose Static_Predicate reflects the list of nonoverridable
aspects given in Ada RM 13.1.1(18.7).
* sem_util.ads, sem_util.adb: Add two new visible subprograms,
Check_Inherited_Nonoverridable_Aspects and Is_Confirming. The
former is used to check the consistency of inherited
nonoverridable aspects from multiple sources. The latter
indicates whether two aspect specifications for a nonoverridable

compiling QGen, Is_Confirming always returns True if

* sem_util.ads, sem_util.adb: Declare and implement a new
predicate, Derivation_Too_Early_To_Inherit. This function
indicates whether a given derived type fails to inherit a given
streaming-related attribute from its parent type because the
declaration of the derived type precedes the corresponding
attribute_definition_clause of the parent.

Derivation_Too_Early_To_Inherit instead of unconditionally
assuming that a parent type's streaming attribute is available
for inheritance by an immediate descendant type.

Derivation_Too_Early_To_Inherit instead of unconditionally
assuming that a parent type's streaming attribute is available
for inheritance by an immediate descendant type.
* exp_attr.adb (Default_Streaming_Unavailable): A new predicate;
given a type, indicates whether predefined (as opposed to
user-defined) streaming operations for the type should be
implemented by raising Program_Error.
(Expand_N_Attribute_Reference): For each of the 4
streaming-related attributes (i.e., Read, Write, Input, Output),

available (including a Stream_Convert pragma), call
Default_Streaming_Unavailable; if that call returns True, then
implement the streaming operation as "raise Program_Error;".

The sincos transformation does not take place on all platforms,
because the libc_has_function target hook disables it by default.

In the testcase below, we're ICEing during constexpr evaluation of the
CONSTRUCTOR {.data={{}, [1 ... 7]={}}} of type 'vector'. The interesting
thing about this CONSTRUCTOR is that it has a RANGE_EXPR index for an
element initializer which doesn't satisfy reduced_constant_expression_p
(because the field 't' is uninitialized).
This is a problem because init_subob_ctx currently punts on setting up a
sub-aggregate initialization context when given a RANGE_EXPR index, so
we later trip over the asserts in verify_ctor_sanity when recursing into
cxx_eval_bare_aggregate on this element initializer.
Fix this by making init_subob_ctx set up an appropriate initialization
context when supplied a RANGE_EXPR index.

In the testcase below, folding of the initializer for 'ret' inside the
instantiated f<lambda>::lambda ends up yielding an initializer for which
potential_constant_expression returns false. This causes finish_function
to mark the lambda as non-constexpr, which ultimately causes us to reject
'f(g)' as a call to a non-constexpr function.
The initializer for 'ret' inside f<lambda>::lambda, prior to folding, is
the CALL_EXPR
<lambda(S)>::operator() (&cb, ({}, <<< Unknown tree: empty_class_expr >>>;))
where the second argument is a COMPOUND_EXPR whose second operand is an
EMPTY_CLASS_EXPR that was formed by build_class_a. cp_fully_fold_init
is able to only partially fold this initializer: it gets rid of the
side-effectless COMPOUND_EXPR to obtain
<lambda(S)>::operator() (&cb, <<< Unknown tree: empty_class_expr >>>)
as the final initializer for 'ret'. This initializer no longer satifies
potential_constant_expression due to the bare EMPTY_CLASS_EXPR which is
not wrapped in a COMPOUND_EXPR.
(cp_fully_fold_init first tries maybe_constant_value on the original
CALL_EXPR, but constexpr evaluation punts upon seeing
__builtin_is_constant_evaluated, since manifestly_const_eval is false.)
To fix this, it seems we could either make cp_fold preserve the
COMPOUND_EXPR trees produced by build_call_a, or we could improve
the constexpr machinery to treat EMPTY_CLASS_EXPR trees as first-class
citizens. Assuming it's safe to continue folding away these
COMPOUND_EXPRs, the second approach seems cleaner, so this patch
implements the second approach.

This makes duplicate_decls differentiate a TYPE_DECL for an alias
template from a TYPE_DECL for one of its template parameters. The
recently added assert in template_parm_to_arg revealed this latent issue

flag.

This fixes expansion of VECTOR_BOOLEAN_TYPE_P VECTOR_CSTs which
when using an integer mode are not always "mask-mode" but may
be using an integer mode when there's no supported vector mode.
The patch makes sure to only go the mask-mode expansion if
the elements do not line up to cover the full integer mode
(when they do and the mode was an actual mask-mode there's
no actual difference in both expansions).

The S/390 backend does not define vec_cmp expanders so far. We relied
solely on expanding vcond. With commit 502d63b6d various testcases
started to ICE now.
This patch just adds the missing expanders to prevent the ICE.
However, there are still a couple of performance-related testcase
regressions with the vcond lowering which have to be fixed
independently.

PR target/97502
* config/s390/vector.md ("vec_cmp<VI_HW:mode><VI_HW:mode>")
("vec_cmpu<VI_HW:mode><VI_HW:mode>"): New expanders.
gcc/testsuite/ChangeLog:
* gcc.dg/pr97502.c: New test.
