-Subject: [PATCH 1/2] toplevel: do not make libstdc++ configure wait for
- libgomp
-
-libstdc++'s configure was made to depend on libgomp's configure in 2007, when
-GLIBCXX_ENABLE_PARALLEL decided whether to enable parallel mode by looking for
-a configured libgomp/omp.h on disk.  Since 2010 the test has instead grepped
-the TARGET_CONFIGDIRS string, which the top level passes in, so nothing on
-disk needs to exist by then.  The comment above the test still describes the
-old behaviour, which is what makes the edge look necessary.
-
-Remove it.  The build time dependency, all-target-libstdc++-v3 on
-configure-target-libgomp, stays, since the parallel mode headers do include
-omp.h when they are compiled.
-
-This shortens the chain in front of libstdc++, which is the last thing to
-finish in every bootstrap stage.
-
-Bootstrapped on aarch64-none-linux-gnu.  Ok for trunk?
-
-ChangeLog:
-
-	* Makefile.def (dependencies): Remove the configure-target-libstdc++-v3
-	on configure-target-libgomp dependency.
-	* Makefile.in: Regenerate.

-Subject: [PATCH 2/2] libstdc++: build the source directories in parallel
-
-libstdc++-v3/src is built by walking SUBDIRS, and automake implements that
-walk as a shell loop.  The per-standard directories are therefore built one
-after another no matter how large -j is, and most of them hold only a handful
-of files.  Sampling the compiler processes during a bootstrap shows a mean of
-between 2 and 4 concurrent compiles against -j64, with exactly one source
-directory active at any moment, and long stretches at a concurrency of two.
-
-libstdc++ is the last thing to finish in every stage, so for most of that time
-nothing else in the build is running and the machine is idle.
-
-The directories are independent of each other, apart from src/experimental,
-which links the convenience archives of c++23, c++26, filesystem and
-libbacktrace.  Give make an explicit target per directory, with that one
-dependency written down, and let it overlap them.  automake's own loop still
-runs afterwards, finds everything built and costs nothing, so the recursion
-for install, clean and the other targets is untouched.
-
-On aarch64 a clean rebuild of libstdc++-v3/src with the final stage compiler
-falls by 62%, and a release checking bootstrap by 12.8%.
-
-Bootstrapped on aarch64-none-linux-gnu.  Ok for trunk?
-
-libstdc++-v3/ChangeLog:
-
-	* src/Makefile.am (all-recursive): Depend on all-parallel-subdirs.
-	(all-parallel-subdirs, all-in-%): New targets.
-	(all-in-experimental): Depend on the directories whose convenience
-	archives it links.
-	* src/Makefile.in: Regenerate.
