We have to extend the genmloop.sh logic a bit to allow outputting to a subdir since it always assumed cwd was the right place. We leave the cgen maintainer rules in the subdirs for now as they aren't normally run, and they rely on cgen logic that has not yet been generalized.

sim: add preliminary support for --enable-targets This doesn't actually create one `run` program like other projects, but creates multiple `run-$arch` targets. While it might not seem that useful initially, this has some nice properties: - Allows us to quickly build all sim targets in a single tree. - Positions us better for converting targets over to a proper multitarget build+install. We don't have the ability to actually run tests against them, but that's due to a limitation in gas: it doesn't support multitarget. If that ever changes, we should be able to turn on our tests too. We can improve the test framework to fallback to a system toolchain if available to help mitigate that.

sim: run: move linking into top-level Automake will run each subdir individually before moving on to the next one. This means that the linking phase, a single threaded process, will not run in parallel with anything else. When we have to link ~32 ports, that's 32 link steps that don't take advantage of parallel systems. On my really old 4-core system, this cuts a multi-target build from ~60 sec to ~30 sec. We eventually want to move all compile+link steps to this common dir anyways, so might as well move linking now for a nice speedup. We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care of the install ourselves rather than letting automake process it.

sim: build: move generated headers to built sources Automake's automatic header deptracking has a bootstrap problem where it can't detect generated headers when compiling. We've been handling that by adding a custom SIM_ALL_RECURSIVE_DEPS variable, but that only works when building objects recursively in subdirs. As we move those out to the top-level, we don't have any recursive steps anymore. The Automake approach is to declare those headers in BUILT_SOURCES. This isn't completely foolproof as the Automake manual documents: it only activates for `make all`, not `make foo.o`, but that shouldn't be a huge limitation as it only affects the initial compile. After that, rebuilds should work fine.

sim: move common flags to default AM_CPPFLAGS Since all host files we compile use these settings, move them out of libcommon.a and into the default AM_CPPFLAGS. This has the effect of dropping the custom per-target automake rules. Currently it saves us ~150 lines, but since it's about ~8 lines per object, the overhead will increase quite a bit as we merge more files into a single build. This also changes the object output names, so we have to tweak the rules that were pulling in the common objects when linking.

Fix igen build The igen build fails for me like: gcc -g -O2 -c ../../binutils-gdb/sim/igen/igen.c -o igen/igen.o In file included from ../../binutils-gdb/sim/igen/igen.c:26: ../../binutils-gdb/sim/igen/lf.h:22:10: fatal error: ansidecl.h: No such file or directory This patch fixes the problem by arranging for igen to find the libiberty includes. This seems slightly hacky to me, because libiberty is not a "build" library, so it can't be linked against. However, since igen currently only includes the header, it seems relatively safe. 2021-05-04 Tom Tromey <tromey@adacore.com> * Makefile.in: Rebuild. * Makefile.am (AM_CPPFLAGS): New variable.

sim: nltvals: pull target syscalls out into a dedicated source file Like we just did for pulling out the errno map, pull out the syscall maps into a dedicated common file. Most newlib ports are using the same syscall map, but not all, which means we have to do a bit more work to migrate. This commit adds the maps and switches the ports using the common default syscall table over to it. Ports using unique syscall tables are still using the old targ-map.c logic. Switching common ports over is easy by checking NL_TARGET, but the ppc code needs a bit more cleanup here hence its larger diff.

We have to extend the genmloop.sh logic a bit to allow outputting to a subdir since it always assumed cwd was the right place. We leave the cgen maintainer rules in the subdirs for now as they aren't normally run, and they rely on cgen logic that has not yet been generalized.

sim: run: move linking into top-level Automake will run each subdir individually before moving on to the next one. This means that the linking phase, a single threaded process, will not run in parallel with anything else. When we have to link ~32 ports, that's 32 link steps that don't take advantage of parallel systems. On my really old 4-core system, this cuts a multi-target build from ~60 sec to ~30 sec. We eventually want to move all compile+link steps to this common dir anyways, so might as well move linking now for a nice speedup. We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care of the install ourselves rather than letting automake process it.
