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: bfin: move libsim.a creation to top-level The objects are still compiled in the subdir, but the creation of the archive itself is in the top-level. This is a required step before we can move compilation itself up, and makes it easier to review. The downside is that each object compile is a recursive make instead of a single one. On my 4 core system, it adds ~100msec to the build per port, so it's not great, but it shouldn't be a big deal. This will go away of course once the top-level compiles objects.

sim: bfin: move linux-fixed-code.h to top-level
2022-11-05 17:15:30 +08:00
sim: build: hoist lists of hw devices up We need these in the top-level to generate libsim.a, but also in the subdirs to generate hw-config.h. Move it to the local.mk, and pass it down when running recursive make. This avoids duplication, and makes it available to both. We can simplify this once we move the various steps up to the top-level too.
