From c0c25232da12f3985041cded1bb7e761d4d0cd1e Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 3 Nov 2022 18:19:13 +0700 Subject: 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/v850/local.mk | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'sim/v850') diff --git a/sim/v850/local.mk b/sim/v850/local.mk index 028eda3..367ca6e 100644 --- a/sim/v850/local.mk +++ b/sim/v850/local.mk @@ -16,6 +16,14 @@ ## You should have received a copy of the GNU General Public License ## along with this program.
