D front-end changes:
- Import dmd v2.099.0-beta.1.
- It's now an error to use `alias this' for partial assignment.
- The `delete' keyword has been removed from the language.
- Using `this' and `super' as types has been removed from the
language, the parser no longer specially handles this wrong code
with an informative error.
D Runtime changes:
- Import druntime v2.099.0-beta.1.
Phobos changes:
- Import phobos v2.099.0-beta.1.
gcc/d/ChangeLog:
* dmd/MERGE: Merge upstream dmd cb49e99f8.
* dmd/VERSION: Update version to v2.099.0-beta.1.
* decl.cc (layout_class_initializer): Update call to NewExp::create.
* expr.cc (ExprVisitor::visit (DeleteExp *)): Remove handling of
deleting arrays and pointers.
(ExprVisitor::visit (DotVarExp *)): Convert complex types to the
front-end library type representing them.
(ExprVisitor::visit (StringExp *)): Use getCodeUnit instead of charAt
to get the value of each index in a string expression.
* runtime.def (DELMEMORY): Remove.
(DELARRAYT): Remove.
* types.cc (TypeVisitor::visit (TypeEnum *)): Handle anonymous enums.
libphobos/ChangeLog:
* libdruntime/MERGE: Merge upstream druntime 55528bd1.
* src/MERGE: Merge upstream phobos 1a3e80ec2.
* testsuite/libphobos.hash/test_hash.d: Update.
* testsuite/libphobos.betterc/test19933.d: New test.
