This patch implements <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1327r1.html>.

2019-12-29Unshare DR_STEP before gimplifying itRichard Sandiford4-2/+19
In this testcase we use an unmasked SVE loop with an Advanced SIMD epilogue (because we don't yet support fully-masked downward loops). The main loop uses a gather load for the strided access while the epilogue loop builds the access from scalars instead. In both cases we gimplify expressions based on the DR_STEP and insert them in the loop preheader. The problem was that the gather load code didn't copy the DR_STEP before gimplifying it, meaning that the epilogue loop tried to reuse a result from the (non-dominating) main loop preheader. It looks at first glance like there could be other instances of this too, but this patch just deals with the gather/scatter case. 2019-12-29 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-stmts.c (vect_get_strided_load_store_ops): Copy DR_STEP before gimplifying it. gcc/testsuite/ * gcc.dg/vect/vect-strided-epilogue-1.c: New test.

2019-12-23[C++] Make same_type_p return false for gnu_vector_type_p differences (PR 92789)Richard Sandiford6-37/+83
As Jason pointed out in the review of the C++ gnu_vector_type_p patch: https://gcc.gnu.org/ml/gcc-patches/2019-12/msg00173.html the real fix for the XFAILs in acle/general-c++/gnu_vectors_*.C is to make same_type_p return false for two types if one is gnu_vector_type_p and the other isn't. This patch does that and fixes the fallout. Originally I'd tried to make it so that "X *" and "Y *" are interconvertible whenever X and Y are, and similarly for "X &" and "Y &". That doesn't fall out naturally though, and is different from how -flax-vector-conversions works. The patch therefore accepts all the consequences of making X and Y !same_type_p instead of trying to work around them. 2019-12-23 Richard Sandiford <richard.sandiford@arm.com> gcc/cp/ PR c++/92789 * typeck.c (structural_comptypes): Make sure that two vector types agree on gnu_vector_type_p. gcc/testsuite/ PR c++/92789 * g++.dg/ext/sve-sizeless-2.C (statements): Expect pointer difference and comparisons between GNU and non-GNU types to be rejected.

2019-12-23[C++] Fix ICE for binding lax vector conversions to references (PR 93014)Richard Sandiford5-3/+109
This test: typedef unsigned int v4si __attribute__ ((vector_size(16))); typedef unsigned char v16qi __attribute__ ((vector_size(16))); extern v16qi x; v4si &y = x; ICEs with: a.c:4:11: internal compiler error: in convert_like_real, at cp/call.c:7670 This started with r260780, which had the effect of making lvalue_kind look through VIEW_CONVERT_EXPR in all cases, not just for location wrappers. This also means that: typedef unsigned int v4si __attribute__ ((vector_size(16))); typedef unsigned char v16qi __attribute__ ((vector_size(16))); extern v16qi x; v4si &y = reinterpret_cast<v4si>(x); is now valid despite the result of the cast being an rvalue. The patch attempts to fix that by calling rvalue on the input to the conversion, so that the tree looks the same as for: extern v16qi x; v4si &y = (v4si)x; which is already handled correctly. 2019-12-23 Richard Sandiford <richard.sandiford@arm.com> gcc/cp/ * cvt.c (ocp_convert): Apply rvalue to the source of vector conversions. * typeck.c (build_reinterpret_cast_1): Likewise. gcc/testsuite/ * g++.dg/ext/vector39.C: New test.

2019-12-22testsuite: Fix run-time tracking down of `libgcc_s'Maciej W. Rozycki2-14/+36
Fix a catastrophic libgo testsuite failure in cross-compilation where the shared `libgcc_s' library cannot be found by the loader at run time in build-tree testing and consequently all test cases fail the execution stage, giving output (here with the `x86_64-linux-gnu' host and the `riscv64-linux-gnu' target, with RISC-V QEMU in the Linux user emulation mode as the target board) like: spawn qemu-riscv64 -E LD_LIBRARY_PATH=.:.../riscv64-linux-gnu/lib64/lp64d/libgo/.libs ./a.exe ./a.exe: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory FAIL: archive/tar To do so rework `gcc-set-multilib-library-path' so as not to rely on the `rootme' TCL variable to have been preset in testsuite invocation, which only works for the GCC test suites and not for library test suites, and also use `remote_exec host' rather than `exec' to invoke the compiler in determination of `libgcc_s' locations, so that the solution works in remote testing as well while also avoiding the hardcoded limit of the executable's path length imposed by `exec'. This is based on an observation that the multilib root directory can be determined by stripping out the multilib directory in effect as printed with the `-print-multi-directory' option from the path produced by the `-print-file-name=' option. And then individual full multilib paths can be assembled for the other multilibs by appending their respective multilib directories to the multilib root directory. Unlike with the old solution the full multilib paths are not checked for the presence of the shared `libgcc_s' library there, but that is supposed to be harmless. Also the full multilib path for the multilib used with the compiler used for testing will now come first, which should reduce run-time processing in the usual case. With this change in place test output instead looks like: spawn qemu-riscv64 -E LD_LIBRARY_PATH=.:.../riscv64-linux-gnu/lib64/lp64d/libgo/.libs:..././gcc/lib64/lp64d:..././gcc/.:..././gcc/lib32/ilp32:..././gcc/lib32/ilp32d:..././gcc/lib64/lp64 ./a.exe PASS PASS: archive/tar No summary comparison, because the libgo testsuite does not provide one in this configuration for some reason, however this change improves overall results from 0 PASSes and 159 FAILs to 133 PASSes and 26 FAILs. gcc/testsuite/ * lib/gcc-defs.exp (gcc-set-multilib-library-path): Use `-print-file-name=' to determine the multilib root directory.

2019-12-20PR c++/92745 - bogus error when initializing array of vectors.Marek Polacek4-8/+39
In r268428 I changed reshape_init_r in such a way that when it sees a nested { } in a CONSTRUCTOR with missing braces, it just returns the initializer: + else if (COMPOUND_LITERAL_P (stripped_init) ... + ++d->cur; + gcc_assert (!BRACE_ENCLOSED_INITIALIZER_P (stripped_init)); + return init; But as this test shows, that's incorrect: if TYPE is an array, we need to proceed to reshape_init_array_1 which will iterate over the array initializers: 6006 /* Loop until there are no more initializers. */ 6007 for (index = 0; 6008 d->cur != d->end && (!sized_array_p || index <= max_index_cst); 6009 ++index) 6010 { and update d.cur accordingly. In other words, when reshape_init gets {{col[0][0], col[1][0], col[2][0], col[3][0]}, {col[0][1], col[1][1], col[2][1], col[3][1]}, {col[0][2], col[1][2], col[2][2], col[3][2]}, {col[0][3], col[1][3], col[2][3], col[3][3]}} we recurse on the first element: {col[0][0], col[1][0], col[2][0], col[3][0]} and we can't just move d.cur to point to {col[0][1], col[1][1], col[2][1], col[3][1]} and return; we need to iterate, so that d.cur ends up being properly updated, and after all initializers have been seen, points to d.end. Currently we skip the loop, wherefore we hit this: 6502 /* Make sure all the element of the constructor were used. Otherwise, 6503 issue an error about exceeding initializers. */ 6504 if (d.cur != d.end) 6505 { 6506 if (complain & tf_error) 6507 error ("too many initializers for %qT", type); 6508 return error_mark_node; 6509 } * decl.c (reshape_init_r): For a nested compound literal, do call reshape_init_{class,array,vector}. * g++.dg/cpp0x/initlist118.C: New test.
