use a c-version of concat-deps.pl
This touch configure.in with a trivial space removal to force a
./bootstrap on the tinderboxes
This make ./bootstrap build a 'build-side' executable concat-deps
and modify LinkTarget.mk to use it instead of concat-deps.pl
The impact is a conservative x10 times improvement in both elapsed and
cpu time in overhead due to DEP generations.
time make -sr build in tail_build after removing
workdir/$INPATH/Dep/LinkTarget/Library/*
(all on Intel X3360, 2.83GHz, 4-core)
before:
elapsed: 116.5 cpu: 115.9
after
elapsed: 24.3 cpu: 23.9
base (no dep processing, i.e no rm of Dep/...)
elapsed: 17.5 cpu: 17.4
overhead ratio:
elapsed: 14.5x cpu: 15x
same with -j6
before:
elapsed: 47 cpu: 116
after:
elapsed: 20.8 cpu: 24
base:
elapsed: 17.5 cpu: 17.5
overhead ratio:
elapsed: 9x cpu: 15x
Note: for now the executable is generated directly in the source tree
(in solevn/bin ). That is not ideal. It and other similar polution
should be moved, to workdir most likely..
For now we just hide the mess under the .gitignore carpet
