2022-08-15d: Fix internal compiler error: Segmentation fault at gimple-expr.cc:88Iain Buclaw1-1/+1
Because complex types are deprecated in the language, the new way to expose native complex types is by defining an enum with a basetype of a library-defined struct that is implicitly treated as-if it is native. As casts are not implicitly added by the front-end when downcasting from enum to its underlying type, we must insert an explicit cast during the code generation pass. PR d/106623 gcc/d/ChangeLog: * d-codegen.cc (underlying_complex_expr): New function. (d_build_call): Handle passing native complex objects as the library-defined equivalent. * d-tree.h (underlying_complex_expr): Declare. * expr.cc (ExprVisitor::visit (DotVarExp *)): Call underlying_complex_expr instead of build_vconvert. gcc/testsuite/ChangeLog: * gdc.dg/torture/pr106623.d: New test.

2022-06-29d: Fix error: aggregate value used where floating point was expectedIain Buclaw1-2/+8
Casting from vector to static array is permitted, and the frontend generates a reinterpret cast, but casting back the other way resulted in an error. This has been fixed to be properly handled in the code generation pass of VectorExp, and the conversion for lvalue and rvalue handling done in convert_expr and convert_for_rvalue respectively. PR d/106139 gcc/d/ChangeLog: * d-convert.cc (convert_expr): Handle casting from array to vector. (convert_for_rvalue): Rewrite vector to array casts of the same element type into a constructor.

2022-06-24d: Add `@register' attribute to compiler and library.Iain Buclaw1-1/+1
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.

2022-06-13d: Improve TypeInfo errors when compiling in -fno-rtti modeIain Buclaw1-18/+18
The existing TypeInfo errors can be cryptic. This alters the diagnostic to include which expression is requiring `object.TypeInfo'. gcc/d/ChangeLog: * d-tree.h (check_typeinfo_type): Add Expression* parameter. (build_typeinfo): Likewise.

2021-11-30d: Import dmd b8384668f, druntime e6caaab9, phobos 5ab9ad256 (v2.098.0-beta.1)Iain Buclaw1-150/+117
The D front-end is now itself written in D, in order to build GDC, you will need a working GDC compiler (GCC version 9.1 or later). GCC changes: - Add support for bootstrapping the D front-end. These add the required components in order to have a D front-end written in D itself. Because the compiler front-end only depends on the core runtime modules, only libdruntime is built for the bootstrap stages. D front-end changes: - Import dmd v2.098.0-beta.1. Druntime changes: - Import druntime v2.098.0-beta.1. Phobos changes: - Import phobos v2.098.0-beta.1. The jump from v2.076.1 to v2.098.0 covers nearly 4 years worth of development on the D programming language and run-time libraries.

2021-06-04d: Fix ICE in gimplify_var_or_parm_decl, at gimplify.c:2755 (PR100882)Iain Buclaw1-6/+1
Constructor calls for temporaries were reusing the TARGET_EXPR_SLOT of a TARGET_EXPR for an assignment, which later got passed to `build_assign', which stripped away the outer TARGET_EXPR, leaving a reference to a lone temporary with no declaration. This stripping away of the TARGET_EXPR also discarded any cleanups that may have been assigned to the expression as well. So now the reuse of TARGET_EXPR_SLOT has been removed, and `build_assign' now constructs assignments inside the TARGET_EXPR_INITIAL slot. This has also been extended to `return_expr', to deal with possibility of a TARGET_EXPR being returned. gcc/d/ChangeLog: PR d/100882 * d-codegen.cc (build_assign): Construct initializations inside TARGET_EXPR_INITIAL.

2020-11-22d: Fix OutOfMemoryError thrown when appending to an array with a side effectIain Buclaw1-24/+43
When appending a character to an array, the result of that concat assignment was not the new value of the array, similarly, when appending an array to another array, side effects were evaluated in reverse to the expected order of evaluation. As of this change, the address of the left-hand side expression is saved and re-used as the result. Its evaluation is now also forced to occur before the concat operation itself is called. gcc/d/ChangeLog: PR d/97889 * expr.cc (ExprVisitor::visit (CatAssignExp *)): Enforce LTR order of evaluation on left and right hand side expressions. gcc/testsuite/ChangeLog: PR d/97889 * gdc.dg/torture/pr97889.d: New test.

2020-08-26d: Fix no RVO when returning struct literals initialized with constructor.Iain Buclaw1-1/+13
Backports a change from upstream dmd that moves front-end NRVO checking from ReturnStatement semantic to the end of FuncDeclaration semantic. In the codegen, retStyle has been partially implemented so that only structs and static arrays return RETstack. This isn't accurate, but don't need to be for the purposes of semantic analysis. If a function either has TREE_ADDRESSABLE or must return in memory, then DECL_RESULT is set as the shidden field for the function. This is used in the codegen pass for ReturnStatement where it is now detected whether a function is returning a struct literal or a constructor function, then the DECL_RESULT is used to directly construct the return value, instead of doing so via temporaries.

2020-07-30d: Fix associative array literals that don't have alignment holes filledIain Buclaw1-24/+9
Associative array literal keys with alignment holes are now filled using memset() prior to usage, with LTR evaluation of side-effects enforced. gcc/d/ChangeLog: PR d/96152 * d-codegen.cc (build_array_from_exprs): New function. * d-tree.h (build_array_from_exprs): Declare. * expr.cc (ExprVisitor::visit (AssocArrayLiteralExp *)): Use build_array_from_exprs to generate key and value arrays. gcc/testsuite/ChangeLog: PR d/96152 * gdc.dg/pr96152.d: New test.
2020-07-30d: Inline bounds checking for simple array assignments.Iain Buclaw1-6/+39
This optimizes the code generation of simple array assignments, inlining the array bounds checking code so there is no reliance on the library routine _d_arraycopy(), which also deals with postblit and copy constructors for non-trivial arrays. gcc/d/ChangeLog: * expr.cc (ExprVisitor::visit (AssignExp *)): Inline bounds checking for simple array assignments. gcc/testsuite/ChangeLog: * gdc.dg/array1.d: New test.
2020-07-30d: Refactor use of built-in memcmp/memcpy/memset into helper functions.Iain Buclaw1-35/+9

(build_memcpy_call): New function. (build_memset_call): New function. (build_float_identity): Call build_memcmp_call. (lower_struct_comparison): Likewise.

2020-07-30d: Move private functions out of ExprVisitor into local staticsIain Buclaw1-154/+159
None of these functions need access to the context pointer of the visitor class, so have been made free standing. gcc/d/ChangeLog: * expr.cc (needs_postblit): Move out of ExprVisitor as a static function.
