2022-11-05d: Add support for vector comparison operatorsIain Buclaw1-7/+19

2022-06-29d: Add SIMD intrinsics module and compiler built-ins.Iain Buclaw1-0/+359
Vectors in D are exposed by the use of the `__vector(T[N])' type, and whilst most unary and binary operations work as you'd expect, there are some operations that are not possible without doing the operation unrolled, or calling some target-specific built-in, or with inline asm. This introduces a new `gcc.simd' module that introduces the following. - Prefetching has been exposed by a convenient `prefetch' function in the library. - Loading and storing from an unaligned address have been exposed by `loadUnaligned' and `storeUnaligned' intrinsics. - Vector permutations have been exposed by `shuffle`, and `shufflevector' intrinsics. - Converting between two vectors with a different element type has been exposed by a `convertvector' intrinsic. - The ternary operator has been exposed with a `blendvector' intrinsic. - Comparison operators have been exposed by `equalMask', `notEqualMask', `greaterMask', and `greaterEqualMask' intrinsics. - Logic operators have been exposed by convenient `notMask', `andAndMask', and `orOrMask' functions in the library. To be compatible with the LLVM D compiler's own SIMD intrinsic module, there is also the addition of an `extractelement' and `insertelement' convenience functions, and an alternative interface for calling the `shufflevector' function. The addition of these intrinsics lowers the boundary for users working in SIMD to get the desired codegen they want out of the compiler. Most of what is present here - apart from tests - is the adding of machinery in the intrinsics suite of functions to do validation on templated intrinsics. Whilst these are still matched from the library by their generic (untyped) signature, there is a still an assumption that what has been instantiated and handed down to the code generator is valid, because why would these definitions be found outside of the in-tree D runtime library? The majority of intrinsics are not templates, so the test on the mangled signature string still guarantees all types are as we expect them to be. However there are still a small handful of other templated intrinsics (core.bitop.{rol,ror}, core.math.toPrec, std.math.traits.isNaN, ...) that are currently unchecked, so would benefit from being included into this built-in checking function at some point in the future. gcc/d/ChangeLog: * intrinsics.cc: Include diagnostic.h, langhooks.h, vec-perm-indices.h. (maybe_set_intrinsic): Add cases for new simd intrinsics. (warn_mismatched_return_type): New function. (warn_mismatched_argument): New function. (build_shuffle_mask_type): New function.

2022-06-28d: Add `@simd` and `@simd_clones` attributes to compiler and libraryIain Buclaw1-0/+40
The `@simd` attribute is equivalent to `__attribute__((simd))`, and `@simd_clones` is a convenience alias to allow specifying whether the compiler should generated masked or non-masked simd clones. gcc/d/ChangeLog: * d-attribs.cc (handle_omp_declare_simd_attribute): New function.

2022-06-24d: Add `@register' attribute to compiler and library.Iain Buclaw1-0/+28
The `@register` attribute specifies that a local or `__gshared` variable is to be given a register storage-class in the C sense of the term, and will be placed into a register named `registerName`. The variable needs to boiled down to a data type that fits the target register. It also cannot have either thread-local or `extern` storage. It is an error to take the address of a register variable. PR d/105413 gcc/d/ChangeLog: * d-attribs.cc (d_handle_register_attribute): New function. (d_langhook_attribute_table): Add register attribute. * d-codegen.cc (d_mark_addressable): Error if taken address of register variable. (build_frame_type): Error if register variable has non-local references. * d-tree.h (d_mark_addressable): Add complain parameter. * decl.cc (get_symbol_decl): Mark register varibles DECL_REGISTER.

2022-06-15d: Add `@no_sanitize' attribute to compiler and library.Iain Buclaw1-0/+35
The `@no_sanitize' attribute disables a particular sanitizer for this function, analogous to `__attribute__((no_sanitize))'. The library also defines `@noSanitize' to be compatible with the LLVM D compiler's `ldc.attributes'. gcc/d/ChangeLog: * d-attribs.cc (d_langhook_attribute_table): Add no_sanitize. (d_handle_no_sanitize_attribute): New function. libphobos/ChangeLog: * libdruntime/gcc/attributes.d (no_sanitize): Define.

2022-06-15d: Add `@visibility' and `@hidden' attributes.Iain Buclaw1-0/+34
The `@visibility' attribute is functionality the same as `__attribute__((visibility))', and `@hidden' is a convenience alias to `@visibility("hidden")' defined in the `gcc.attributes' module. As the visibility of a symbol is also indirectly controlled by the `export' keyword, the handling of this in the code generation pass has been improved so that conflicts will be appropriately diagnosed. gcc/d/ChangeLog: * d-attribs.cc (d_langhook_attribute_table): Add visibility. (insert_type_attribute): Use decl_attributes instead of merge_attributes. (insert_decl_attribute): Likewise. (apply_user_attributes): Do nothing when no UDAs applied. (d_handle_visibility_attribute): New function. * d-gimplify.cc (d_gimplify_binary_expr): Adjust. * d-tree.h (set_visibility_for_decl): Declare. * decl.cc (get_symbol_decl): Move setting of visibility flags to... (set_visibility_for_decl): ... here. New function. * types.cc (TypeVisitor::visit (TypeStruct *)): Call set_visibility_for_decl(). (TypeVisitor::visit (TypeClass *)): Likewise. gcc/testsuite/ChangeLog: * gdc.dg/attr_visibility1.d: New test. * gdc.dg/attr_visibility2.d: New test. * gdc.dg/attr_visibility3.d: New test. libphobos/ChangeLog: * libdruntime/gcc/attributes.d (visibility): Define.

2022-04-26libphobos: Don't call free on the TLS array in the emutls destroy function.Iain Buclaw1-4/+4
Fixes a segfault seen on Darwin when a GC scan is ran after a thread has been destroyed. As the global emutlsArrays hash still has a reference to the array itself, and tries to iterate all elements. Setting the length to zero frees all allocated elements in the array, and ensures that it is skipped when the _d_emutls_scan is called. libphobos/ChangeLog: * libdruntime/gcc/emutls.d (emutlsDestroyThread): Clear the per-thread TLS array, don't call free().

2021-04-08d: Update language attribute support, and implement gcc.attributesIain Buclaw3-10/+608
D attribute support has been updated to have a baseline parity with the LLVM D compiler's own `ldc.attributes'. The handler that extracts GCC attributes from a list of UDAs has been improved to take care of some mistakes that could have been warnings. UDAs attached to field variables are also now processed for any GCC attributes attached to them. The following new attributes have been added to the D front-end: - @attribute("alloc_size") - @attribute("used") - @attribute("optimize") - @attribute("restrict") - @attribute("cold") - @attribute("noplt") - @attribute("target_clones") - @attribute("no_icf") - @attribute("noipa") - @attribute("symver") With convenience aliases in a new `gcc.attributes' module to match the same naming convention as `ldc.attributes': - @allocSize() - @assumeUsed - @fastmath - @naked - @restrict - @cold - @noplt - @optStrategy() - @polly - @section() - @target() - @weak The old gcc.attribute module has been deprecated, along with the removal of the following attribute handlers: - @attribute("alias"): Has been superseded by `pragma(mangle)'. - @attribute("forceinline"): Renamed to always_inline. gcc/d/ChangeLog: * d-attribs.cc: Include fold-const.h and opts.h.

2020-11-27libphobos: Fix segfault at run-time when using custom Fibers (PR 98025)Iain Buclaw1-0/+3
When libphobos is configured with --enable-cet, this adds extra fields to the Fiber class to support the ucontext_t fallback implementation. These fields get omitted when compiling user code unless they also used `-fversion=CET' to build their project, which resulted in data being overwritten from within swapcontext(). On reviewing the ucontext_t definitions, it was found that the shadow stack fields were missing, and the struct size didn't match up on X32. This has been fixed in upstream druntime and merged down here.

2019-04-13libphobos: Move rt.sections modules to gcc.sectionsIain Buclaw7-0/+2124
These modules depend on a mixture between how the compiler emits run-time module information, and what functions are exposed by the platform to inquire about loaded global and thread-local data sections. As the upstream implementation is written to work only with how the reference D compiler writes out data, much of what is present does not apply to the GCC D front-end. So it has been moved to a non-upstream location in the source tree, where most of it will be rewritten once each port has been completed. The only tested module sections/elf_shared.d has been cleaned up so that all deprecated declarations have been removed, as well as the brittle module collision checking, which required bss_sections.c. All other ports have been left unchanged apart from a commonizing of attributes. libphobos/ChangeLog: 2019-04-13 Iain Buclaw <ibuclaw@gdcproject.org> * libdruntime/Makefile.am (DRUNTIME_CSOURCES): Remove bss_sections.c.
