2011-12-24prep work to eliminated Env.*.sh, introduce config_{host,build}.mkNorbert Thiebaud
This introduce config_host.mk and config_build.mk generated from config_host.mk.in The intent is for that file to be both sourcable in a shell and includable in a gnu Makefile. Eventually all the environment set-up will be in config_host.mk.in and so there won't be a need to source anything in shell before make.
2011-12-18force the use of gcc on cygwin for concat-deps.cNorbert Thiebaud
2011-12-17use a c-version of concat-deps.plNorbert Thiebaud
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
