d: Merge upstream dmd d7772a2369, phobos 5748ca43f.
In upstream dmd, the compiler front-end and run-time have been merged
together into one repository. Both dmd and libdruntime now track that.
D front-end changes:
- Deprecated `scope(failure)' blocks that contain `return' statements.
- Deprecated using integers for `version' or `debug' conditions.
- Deprecated returning a discarded void value from a function.
- `new' can now allocate an associative array.
D runtime changes:
- Added avx512f detection to core.cpuid module.
Phobos changes:
- Changed std.experimental.logger.core.sharedLog to return
shared(Logger).
gcc/d/ChangeLog:
* dmd/MERGE: Merge upstream dmd d7772a2369.
* dmd/VERSION: Bump version to v2.100.1.
* d-codegen.cc (get_frameinfo): Check whether decision to generate
closure changed since semantic finished.
* d-lang.cc (d_handle_option): Remove handling of -fdebug=level and
-fversion=level.
* decl.cc (DeclVisitor::visit (VarDeclaration *)): Generate evaluation
of noreturn variable initializers before throw.
* expr.cc (ExprVisitor::visit (AssignExp *)): Don't generate
assignment for noreturn types, only evaluate for side effects.
* lang.opt (fdebug=): Undocument -fdebug=level.
(fversion=): Undocument -fversion=level.
libphobos/ChangeLog:
* configure: Regenerate.
* configure.ac (libtool_VERSION): Update to 4:0:0.
* libdruntime/MERGE: Merge upstream druntime d7772a2369.
* libdruntime/Makefile.am (DRUNTIME_DSOURCES): Add
core/internal/array/duplication.d.
* libdruntime/Makefile.in: Regenerate.
* src/MERGE: Merge upstream phobos 5748ca43f.
* testsuite/libphobos.gc/nocollect.d:
