2021-01-26d: Merge upstream dmd 609c3ce2d, phobos 3dd5df686Iain Buclaw9-10/+51
D front-end changes: - Contracts for pre- and postconditions are now implicitly "this" const, so that state can no longer be altered in these functions. - Inside a constructor scope, assigning to aggregate declaration members is done by considering the first assignment as initialization and subsequent assignments as modifications of the constructed object. For const/immutable fields the initialization is accepted in the constructor but subsequent modifications are not. However this rule did not apply when inside a constructor scope there is a call to a different constructor. This been changed so it is now an error when there's a double initialization of immutable fields inside a constructor. Phobos changes: - Don't run unit-tests for unsupported clocks in std.datetime. The phobos and phobos_shared tests now add -fversion=Linux_Pre_2639 if required. - Deprecate public extern(C) bindings for getline and getdelim in std.stdio.

Adds the following new `__traits' to the D language. - isDeprecated: used to detect if a function is deprecated. - isDisabled: used to detect if a function is marked with @disable. - isFuture: used to detect if a function is marked with @__future. - isModule: used to detect if a given symbol represents a module, this enhancement also adds support using `is(sym == module)'. - isPackage: used to detect if a given symbol represents a package, this enhancement also adds support using `is(sym == package)'. - child: takes two arguments. The first must be a symbol or expression and the second must be a symbol, such as an alias to a member of the first 'parent' argument. The result is the second 'member' argument interpreted with its 'this' context set to 'parent'. This is the inverse of `__traits(parent, member)'. - isReturnOnStack: determines if a function's return value is placed on the stack, or is returned via registers. - isZeroInit: used to detect if a type's default initializer has no non-zero bits. - getTargetInfo: used to query features of the target being compiled for, the back-end can expand this to register any key to handle the given argument, however a reliable subset exists which includes "cppRuntimeLibrary", "cppStd", "floatAbi", and "objectFormat". - getLocation: returns a tuple whose entries correspond to the filename, line number, and column number of where the argument was declared. - hasPostblit: used to detect if a type is a struct with a postblit. - isCopyable: used to detect if a type allows copying its value. - getVisibility: an alias for the getProtection trait.

2020-12-31d: Mangled Symbols now back reference types and identifiersIain Buclaw3-166/+271
Symbols with extern(D) linkage are now mangled using back references to types and identifiers if these occur more than once in the mangled name as emitted before. This reduces symbol length, especially with chained expressions of templated functions with Voldemort return types. For example, the average symbol length of the 127000+ symbols created by a libphobos unittest build is reduced by a factor of about 3, while the longest symbol shrinks from 416133 to 1142 characters.

2020-11-20configury: Fix up --enable-link-serialization supportJakub Jelinek1-3/+3
Eric reported that the --enable-link-serialization changes seemed to cause the binaries to be always relinked, for example from the gcc/ directory of the build tree: make [relink of gnat1, brig1, cc1plus, d21, f951, go1, lto1, ...] make [relink of gnat1, brig1, cc1plus, d21, f951, go1, lto1, ...] Furthermore as reported in PR, it can cause problems during make install where make install rebuilds the binaries again. The problem is that for make .PHONY targets are just "rebuilt" always, so it is very much undesirable for the cc1plus$(exeext) etc. dependencies to include .PHONY targets, but I was using them - cc1plus.prev which would depend on some *.serial and e.g. cc1.serial depending on c and c depending on cc1$(exeext). The following patch rewrites this so that *.serial and *.prev aren't .PHONY targets, but instead just make variables. I was worried that the order in which the language makefile fragments are included (which is quite random, what order we get from the filesystem matching */config-lang.in) would be a problem but it seems to work fine - as it uses make = rather than := variables, later definitions are just fine for earlier uses as long as the uses aren't needed during the makefile parsing, but only in the dependencies of make targets and in their commands. 2020-11-20 Jakub Jelinek <jakub@redhat.com> PR other/97911 gcc/ * configure.ac: In SERIAL_LIST use lang words without .serial suffix.

2020-11-18configury: --enable-link-serialization supportJakub Jelinek1-2/+5
When performing LTO bootstraps, especially when using tmpfs for /tmp, one can run a machine to halt when using higher levels of parallelism and a large number of FEs, because there are too many concurrent LTO link commands running at the same time and each one of them puts most of the middle-end/backend objects into /tmp. We have --enable-link-mutex configure option, but --enable-link-mutex has a big problem that it decreases number of available jobs by the number of link commands waiting for the lock, so e.g. when doing make -j32 build with 11 different big programs linked with $(LLINKER) we end up with just 22 effective jobs, and with e.g. make -j8 with those 11 different big programs we actually most likely serialize everything during linking onto a single job. The following patch implements a new configure option, --enable-link-serialization, which implements different serialization and as it doesn't use the mutex, just modifying the old option to be implemented differently would be strange. We can deprecate and later remove the old option. The new option doesn't use any shell mutexes, but uses make dependencies. The option is implemented inside of gcc/ configure and Makefiles, which means that even inside of gcc/ make all (as well as e.g. make lto-dump) will serialize and build all previous large binaries when configured this way. One can always make -j32 cc1 DO_LINK_SERIALIZATION= to avoid that. Furthermore, I've implemented the idea I wrote about, so that --enable-link-serialization is the same as --enable-link-serialization=1 and means the large link commands are serialized, one can (the default) --disable-link-serialization which will cause all links to be parallelizable, but one can also --enable-link-serialization=3 etc. which says that at most 3 of the large link commands can run concurrently. And finally I've implemented (only if the serialization is enabled) simple progress bars for the linking. With --enable-link-serialization and e.g. the 5 large links I have in my current tree (cc1, cc1plus, f951, lto1 and lto-dump), before the linking it prints Linking |==-- | 20% and after it Linking |==== | 40% (each == characters stand for already finished links, each -- characters stand for the link being started). With --enable-link-serialization=3 it will change the way the start is printed, one will get: Linking |-- | 0% at the start of cc1 link, Linking |>>-- | 0% at the start of the second large link and Linking |>>>>-- | 0% at the start of the third large link, where the >> characters stand for already pending links. The printing at the end of link command is the same as with the full serialization, i.e. for the above 3: Linking |== | 20% Linking |==== | 40% Linking |====== | 60% but one could actually get them in any order depending on which of those 3 finishes first - to get it 100% accurate I'd need to add some directory with files representing finished links or similar, doesn't seem worth it. 2020-11-18 Jakub Jelinek <jakub@redhat.com> gcc/ * configure.ac: Add $lang.prev rules, INDEX.$lang and SERIAL_LIST and SERIAL_COUNT variables to Make-hooks.
