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. |

This is the m32r simulator directory. It is still work-in-progress. The current sources are reasonably well tested and lots of features are in. However, there's lots more yet to come. There are lots of machine generated files in the source directory! They are only generated if you configure with --enable-cgen-maint, similar in behaviour to Makefile.in, configure under automake/autoconf. For details on the generator, see ../../cgen. devo/cgen isn't part of the comp-tools module yet. You'll need to check it out manually (also akin to automake/autoconf).
