2019-12-04[C++] Opt out of GNU vector extensions for built-in SVE typesRichard Sandiford8-19/+1038
This is the C++ equivalent of r277950. The changes are very similar to there. Perhaps the only noteworthy thing (that I know of) is that the patch continues to treat !gnu_vector_type_p vector types as literal types/potential constexprs. Disabling the GNU vector extensions shouldn't in itself stop the types from being literal types, since whatever the target provides instead might be constexpr material. 2019-12-04 Richard Sandiford <richard.sandiford@arm.com> gcc/cp/ * cp-tree.h (CP_AGGREGATE_TYPE_P): Check for gnu_vector_type_p instead of VECTOR_TYPE. * call.c (build_conditional_expr_1): Restrict vector handling to vectors that satisfy gnu_vector_type_p. * cvt.c (ocp_convert): Only allow vectors to be converted to bool if they satisfy gnu_vector_type_p.

PR92760 exposed one issue that VECTOR_UNIT_NONE_P (V2DImode) is true on Power7 then we won't return it as preferred_simd_mode but ISA 2.06 (Power7) does introduce partial support on vector doubleword (very limitted) and more basic support origins from ISA 2.07 (Power8) though.

2019-12-03Don't install unnecessary ARRAY_REF element sizesRichard Sandiford4-17/+41
Even EXACT_DIV_EXPR doesn't distribute across addition for wrapping types, so in general we can't fold EXACT_DIV_EXPRs of POLY_INT_CSTs at compile time. This was causing an ICE when trying to gimplify the element size field in an ARRAY_REF. If the result of that EXACT_DIV_EXPR is an invariant, we don't bother recording it in the ARRAY_REF and simply read the element size from the element type. This avoids the overhead of doing: /* ??? tree_ssa_useless_type_conversion will eliminate casts to sizetype from another type of the same width and signedness. */ if (TREE_TYPE (aligned_size) != sizetype) aligned_size = fold_convert_loc (loc, sizetype, aligned_size); return size_binop_loc (loc, MULT_EXPR, aligned_size, size_int (TYPE_ALIGN_UNIT (elmt_type))); each time array_ref_element_size is called. So rather than read array_ref_element_size, do some arithmetic on it, and only then check whether the result is an invariant, we might as well check whether the element size is an invariant to start with. We're then directly testing whether array_ref_element_size gives a reusable value. For consistency, the patch makes the same change for the offset field in a COMPONENT_REF, although I don't think that can trigger yet. 2019-12-03 Richard Sandiford <richard.sandiford@arm.com> gcc/ * gimplify.c (gimplify_compound_lval): Don't gimplify and install an array element size if array_element_size is already an invariant. Similarly don't gimplify and install a field offset if component_ref_field_offset is already an invariant. gcc/testsuite/ * gcc.target/aarch64/sve/acle/general-c/struct_1.c: New test.

2019-12-03Mark constant-sized objects as addressable if they have poly-int accessesRichard Sandiford4-0/+50
If SVE code is written for a specific vector length, it might load from or store to fixed-sized objects. This needs to work even without -msve-vector-bits=N (which should never be needed for correctness). There's no way of handling a direct poly-int sized reference to a fixed-size register; it would have to go via memory. And in that case it's more efficient to mark the fixed-size object as addressable from the outset, like we do for array references with non-constant indices. 2019-12-03 Richard Sandiford <richard.sandiford@arm.com> gcc/ * cfgexpand.c (discover_nonconstant_array_refs_r): If an access with POLY_INT_CST size is made to a fixed-size object, force the object to live in memory. gcc/testsuite/ * gcc.target/aarch64/sve/acle/general/deref_1.c: New test.

2019-12-03PR c++/91363 - P0960R3: Parenthesized initialization of aggregates.Marek Polacek41-33/+868
This patch implements C++20 P0960R3: Parenthesized initialization of aggregates (<wg21.link/p0960>; see R0 for more background info). Essentially, if you have an aggregate, you can now initialize it by (x, y), similarly to {x, y}. E.g. struct A { int x, y; // no A(int, int) ctor (see paren-init14.C for = delete; case) }; A a(1, 2); The difference between ()-init and {}-init is that narrowing conversions are permitted, designators are not permitted, a temporary object bound to a reference does not have its lifetime extended, and there is no brace elision. Further, things like int a[](1, 2, 3); // will deduce the array size const A& r(1, 2.3, 3); // narrowing is OK int (&&rr)[](1, 2, 3); int b[3](1, 2); // b[2] will be value-initialized now work as expected. Note that char f[]("fluff"); has always worked and this patch keeps it that way. Also note that A a((1, 2)) is not the same as A a{{1,2}}; the inner (1, 2) remains a COMPOUND_EXPR. The approach I took was to handle (1, 2) similarly to {1, 2} -- conjure up a CONSTRUCTOR, and introduce LOOKUP_AGGREGATE_PAREN_INIT to distinguish between the two. This kind of initialization is only supported in C++20; I've made no attempt to support it in earlier standards, like we don't support CTAD pre-C++17, for instance. * c-cppbuiltin.c (c_cpp_builtins): Predefine __cpp_aggregate_paren_init=201902 for -std=c++2a. * call.c (build_new_method_call_1): Handle parenthesized initialization of aggregates by building up a CONSTRUCTOR.

2019-12-03Diagnose use of [*] in old-style parameter definitions (PR c/88704).Joseph Myers4-0/+23
GCC wrongly accepts [*] in old-style parameter definitions because because parm_flag is set on the scope used for those definitions and, unlike the case of a prototype in a function definition, there is no subsequent check to disallow this invalid usage. This patch adds such a check. (At this point we don't have location information for the [*], so the diagnostic location isn't ideal.) Bootstrapped with no regressions for x86_64-pc-linux-gnu.

2019-12-02[Committed][Arm][testsuite] Fix failure for arm-fp16-ops-*.CSudakshina Das2-10/+14
Since r275022 which deprecates some uses of volatile, all arm-fp16-ops-*.C were failing with warnings of deprecated valatile uses on arm-none-eabi and arm-none-linux-gnueabihf. This patch removes the volatile declarations from the header. Since none of the tests are run with any high optimization levels, this should change should not prevent the real function of the tests. gcc/testsuite/ChangeLog: 2019-12-02 Sudakshina Das <sudi.das@arm.com> * g++.dg/ext/arm-fp16/arm-fp16-ops.h: Remove volatile keyword.

2019-12-02libstdc++: Fix try_lock_until and try_lock_shared_until on arbitrary clockMike Crowe2-4/+31
This is the equivalent to PR libstdc++/91906, but for shared_mutex. A non-standard clock may tick more slowly than std::chrono::steady_clock. This means that we risk returning false early when the specified timeout may not have expired. This can be avoided by looping until the timeout time as reported by the non-standard clock has been reached. Unfortunately, we have no way to tell whether the non-standard clock ticks more quickly that std::chrono::steady_clock. If it does then we risk returning later than would be expected, but that is unavoidable without waking up periodically to check, which would be rather too expensive. François Dumont pointed out[1] a flaw in an earlier version of this patch that revealed a hole in the test coverage, so I've added a new test that try_lock_until acts as try_lock if the timeout has already expired.
