2019-10-26rs6000: Fix allocate_stack in a corner case (PR91289)Segher Boessenkool2-4/+15
When we have -fstack-limit-symbol with sysv we can end up with a non- existing instruction (you cannot add an immediate to register 0). Fix this by using register 11 instead. It might be used for something else already though, so save and restore its value around this. In optimizing compiles these extra moves are usually removed again: the restore by cprop_hardreg, and then the save by rtl_dce. PR target/91289 * config/rs6000/rs6000-logue.c (rs6000_emit_allocate_stack): Don't add an immediate to r0; use r11 instead. Save and restore r11 to r0 around this. From-SVN: r277472

All of these special member functions do exactly what the compiler would do anyway.

2019-10-25Fix reductions for fully-masked loopsRichard Sandiford19-60/+144
Now that vectorizable_operation vectorises most loop stmts involved in a reduction, it needs to be aware of reductions in fully-masked loops. The LOOP_VINFO_CAN_FULLY_MASK_P parts of vectorizable_reduction now only apply to cases that use vect_transform_reduction. This new way of doing things is definitely an improvement for SVE though, since it means we can lift the old restriction of not using fully-masked loops for reduction chains. 2019-10-25 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-loop.c (vectorizable_reduction): Restrict the LOOP_VINFO_CAN_FULLY_MASK_P handling to cases that will be handled by vect_transform_reduction.

2019-10-24Revert ABI changes to std::allocator in C++20Jonathan Wakely7-10/+64
The recent C++20 changes to remove the std::allocator<void> explicit specialization and the destructor in the std::allocator primary template change the result of some is_trivially_xxx type traits. To avoid those changes, this patch restores the explicit specialization and the destructor. In order to meet the C++20 requirements the std::allocator<void> explicit specialization must provide the same interface as the primary template (except for the unusable allocate and deallocate member functions) and the destructor in the primary template must be constexpr. * include/bits/allocator.h (allocator<void>): Restore the explicit specialization for C++20, but make its API consistent with the primary template. (allocator::~allocator()): Restore the destructor for C++20, but make it constexpr. * testsuite/20_util/allocator/rebind_c++20.cc: Check allocator<void>. * testsuite/20_util/allocator/requirements/typedefs_c++20.cc: Likewise. * testsuite/20_util/allocator/void.cc: Check that constructors and destructors are trivial. Check for converting constructor in C++20. * testsuite/ext/malloc_allocator/variadic_construct.cc: Simplify dejagnu target selector. * testsuite/ext/new_allocator/variadic_construct.cc: Likewise.

Power and IBM Z require a function prototype if a vector argument is passed.

Add argument type to prototype of k. From-SVN: r277409

2019-10-24Simplify common case of use_future_t that uses std::allocatorJonathan Wakely2-2/+48
There is no need to store and pass around the allocator object when it's an instance of std::allocator. Define a partial specialization of std::use_future_t and the corresponding completion token so that no allocator is stored. Overload the completion handler constructor to not expect an allocator to be stored. * include/experimental/executor (__use_future_ct, use_future_t): Define partial specializations for std::allocator.
