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 Jelinek1-3/+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.

2020-11-11fortran: Fix up gfc_typename CHARACTER length handling [PR97768]Jakub Jelinek1-3/+25
The first testcase below ICEs when f951 is 32-bit (or 64-bit big-endian). The problem is that ex->ts.u.cl && ex->ts.u.cl->length are both non-NULL, but ex->ts.u.cl->length->expr_type is not EXPR_CONSTANT, but EXPR_FUNCTION. value.function.actual and value.function.name are in that case pointers, but value._mp_alloc and value._mp_size are 4 byte integers no matter what. So, in 64-bit little-endian the function returns most of the time incorrect CHARACTER(0) because the most significant 32 bits of the value.function.actual pointer are likely 0. Anyway, the following patch is an attempt to get all the cases right. Uses ex->value.character.length only for ex->expr_type == EXPR_CONSTANT (i.e. CHARACTER literals), handles the deferred lengths, assumed lengths, known constant lengths and finally if the length is something other, just doesn't print it, i.e. prints just CHARACTER (for default kind) or CHARACTER(KIND=4) (for e.g. kind 4). 2020-11-11 Jakub Jelinek <jakub@redhat.com> PR fortran/97768 gcc/fortran/ * misc.c (gfc_typename): Use ex->value.character.length only if ex->expr_type == EXPR_CONSTANT.

2020-11-06Fortran: Fix type-decl for PDT / wrong-code pdt_14.f03 issue [PR97652]Tobias Burnus1-0/+3
Parameterized derived types are handled in a special way and start with 'Pdt'. If the 'P' is not uppercase, gfc_get_derived_type (which calls gfc_get_module_backend_decl) does not find the existing declaration and builds a new type. The middle end then sees those types as being different and nonalising, creating an endless loop for pdt_14.f03. gcc/fortran/ChangeLog: PR fortran/97652 * module.c (mio_symbol): Fix symbol name for pdt_type.

This patch cleans up the interface to the dependency generation a little. We now only check the option in one place, and the cpp_get_deps function returns nullptr if there are no dependencies. I also reworded the -MT and -MQ help text to be make agnostic -- as there are ideas about emitting, say, JSON. libcpp/ * include/mkdeps.h: Include cpplib.h (deps_write): Adjust first parm type. * mkdeps.c: Include internal.h (make_write): Adjust first parm type.
