D front-end changes:
- Import dmd v2.099.1-beta.1.
- The address of NRVO variables is now stored in scoped closures
when they have nested references.
- Using `__traits(parameters)' in foreach loops now always returns
the parameters to the function the foreach appears within.
Previously, when used inside a `foreach' using an overloaded
`opApply', the trait would yield the parameters to the delegate.
- The deprecation period of unannotated `asm' blocks has been ended.
- The `inout' attribute no longer implies the `return' attribute.
- Added new `D_PreConditions', `D_PostConditions', and
`D_Invariants' version identifiers.
D runtime changes:
- Import druntime v2.099.1-beta.1.
Phobos changes:
- Import phobos v2.099.1-beta.1.
- `Nullable' in `std.typecons' can now act as a range.
- std.experimental.logger default level changed to `info' instead of
`warning'.
gcc/d/ChangeLog:
* dmd/MERGE: Merge upstream dmd 47871363d.
* d-builtins.cc (d_init_versions): Add predefined version identifiers
D_PreConditions, D_PostConditions, and D_Invariants.
* d-codegen.cc (d_build_call): Update for new front-end interface.
(build_frame_type): Generate reference field for NRVO variables with
nested references.
(build_closure): Generate assignment of return address to closure.
* d-tree.h (DECL_INSTANTIATED): Use DECL_LANG_FLAG_2.
(bind_expr): Remove.
* decl.cc (DeclVisitor::visit (FuncDeclaration *)): Update for new
front-end interface.
(get_symbol_decl): Likewise.
(get_decl_tree): Check DECL_LANG_FRAME_FIELD before DECL_LANG_NRVO.
Dereference the field when both are set.
* expr.cc (ExprVisitor::visit (DeleteExp *)): Update for new front-end
interface.
* modules.cc (get_internal_fn): Likewise.
* toir.cc (IRVisitor::visit (ReturnStatement *)): Likewise.
libphobos/ChangeLog:
* libdruntime/MERGE: Merge upstream druntime c52e28b7.
* libdruntime/Makefile.am (DRUNTIME_DSOURCES_OPENBSD): Add
core/sys/openbsd/pwd.d.
* libdruntime/Makefile.in: Regenerate.
* src/MERGE: Merge upstream phobos 99e9c1b77.
* testsuite/libphobos.exceptions/message_with_null.d: New test.
gcc/testsuite/ChangeLog:
* gdc.dg/nrvo1.d: New test.
