2021-05-26Warn on type punning that toggles scalar storage orderEric Botcazou2-0/+31
As documented in the manual, we do not support type punning that toggles the scalar storage order, so this adds a warning for the case of unions. gcc/c/ PR c/100653 * c-decl.c (finish_struct): Warn for a union containing an aggregate field with a differing scalar storage order. gcc/testsuite/ * gcc.dg/sso-13.c: New test.
2021-05-26arm: Auto-vectorization for MVE: vaddvChristophe Lyon4-14/+53
This patch adds support for the reduc_plus_scal optab with MVE, which maps to the vaddv instruction. It moves the reduc_plus_scal_<mode> expander from neon.md to vec-common.md and adds support for MVE to it. Since vaddv uses a 32-bits accumulator, we have to truncate it's result. For instance: int32_t test__s8x16 (int8_t *a) { int i; int8_t result = 0; for (i=0; i<16; i++) { result += a[i]; } return result; } is compiled into: vldrb.8 q3, [r0] vaddv.s8 r0, q3 sxtb r0, r0 bx lr If we used uint8_t instead of int8_t, we still use vaddv.s8 r0, q3, but truncate with uxtb r0, r0. 2021-05-25 Christophe Lyon <christophe.lyon@linaro.org> gcc/ * config/arm/mve.md (mve_vaddvq_<supf><mode>): Prefix with '@'. * config/arm/neon.md (reduc_plus_scal_<mode>): Move to .. * config/arm/vec-common.md: .. here.

2021-05-26c++: constexpr and copy elision within mem init [PR100368]Patrick Palka2-7/+24
In the testcase below, the member initializer b(f()) inside C's default constructor is encoded as a TARGET_EXPR wrapping the CALL_EXPR f() in C++17 mode. During massaging of this constexpr constructor, build_target_expr_with_type called from bot_manip on this initializer tries to add an extra copy using B's implicitly deleted copy constructor rather than just preserving the copy elision. Since it's wrong to introduce an extra copy when initializing a temporary from a CALL_EXPR, this patch makes build_target_expr_with_type avoid calling force_rvalue in this case. Additionally, bot_manip should be copying TARGET_EXPRs in a more oblivious manner, so this patch makes bot_manip use force_target_expr instead of build_target_expr_with_type. And since bot_manip is now no longer a caller, we can remove the void initializer handling in build_target_expr_with_type. PR c++/100368 gcc/cp/ChangeLog: * tree.c (build_target_expr_with_type): Don't call force_rvalue on CALL_EXPR initializer. Simplify now that bot_manip is no longer a caller.

2021-05-26c++: Fix reference NTTP binding to noexcept fn [PR97420]Patrick Palka3-26/+23
Here, in C++17 mode, convert_nontype_argument_function is rejecting binding a non-noexcept function reference template parameter to a noexcept function (encoded as the template argument '*(int (&) (int)) &f'). The first roadblock to making this work is that the argument is wrapped an an implicit INDIRECT_REF, so we need to unwrap it before calling strip_fnptr_conv. The second roadblock is that the NOP_EXPR cast converts from a function pointer type to a reference type while simultaneously removing the noexcept qualification, and fnptr_conv_p doesn't consider this cast to be a function pointer conversion. This patch fixes this by making fnptr_conv_p treat REFERENCE_TYPEs and POINTER_TYPEs interchangeably. Finally, in passing, this patch also simplifies noexcept_conv_p by removing a bunch of redundant checks already performed by its only caller fnptr_conv_p. PR c++/97420 gcc/cp/ChangeLog: * cvt.c (noexcept_conv_p): Remove redundant checks and simplify. (fnptr_conv_p): Don't call non_reference.

2021-05-26openmp: Fix up handling of target constructs in offloaded routines [PR100573]Jakub Jelinek2-8/+43
OpenMP Nesting of Regions restrictions say: - If a target update, target data, target enter data, or target exit data construct is encountered during execution of a target region, the behavior is unspecified. - If a target construct is encountered during execution of a target region and a device clause in which the ancestor device-modifier appears is not present on the construct, the behavior is unspecified. That wording is about the dynamic (runtime) behavior, not about lexical nesting, so while it is UB if omp target * is encountered in the target region, we need to make it compile and link (for lexical nesting of target * inside of target we actually emit a warning). To make this work, I had to do multiple changes. One was to mark .omp_data_{sizes,kinds}.* variables when static as "omp declare target". Another one was to add stub GOMP_target* entrypoints to nvptx and gcn libgomp.a. The entrypoint functions shouldn't be called or passed in the offload regions, otherwise libgomp: cuLaunchKernel error: too many resources requested for launch was reported; fixed by changing those arguments of calls to GOMP_target_ext to NULL. And we didn't mark the entrypoints "omp target entrypoint" when the caller has been "omp declare target". 2021-05-26 Jakub Jelinek <jakub@redhat.com> PR libgomp/100573 gcc/ * omp-low.c: Include omp-offload.h.

2021-05-24compiler: mark global variables whose address is takenIan Lance Taylor7-184/+276
To implement this, change the backend to use flag bits for variables. Fixes https://gcc.gnu.org/PR100537 PR go/100537 * go-gcc.cc (class Gcc_backend): Update methods that create variables to take a flags parameter. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/322129
2021-05-24Fusion patterns for add-logical/logical-addAaron Sawdey6-279/+797

2021-05-24VARYING ranges of different sizes should not be equal.Aldy Hernandez1-1/+12
VARYING ranges are just normal ranges that span the entire domain. Such ranges have had end-points for a few releases now, and the fact that the legacy code was still treating all VR_VARYING the same was an oversight. This patch fixes the oversight to match the multi-range behavior. gcc/ChangeLog: * value-range.cc (irange::legacy_equal_p): Check type when comparing VR_VARYING types. (range_tests_legacy): Test comparing VARYING ranges of different sizes.
