buildsys: cache build flags in vars 2012-01-15T00:32:29+00:00 Mike Frysinger vapier@gentoo.org 2011-11-27T05:15:07+00:00 a899b909abe14e8e35a81997c828201d1beaff78 Running `make clean` atm takes like 20 seconds because every subdir re-evaluates all the toolchain flags. Add some helpers to automate the process of setting up variables to cache the result of tests, as well as the checking of an already set flag. Now `make clean` takes like 2 seconds on my system.

ldso: setup search path even when there are no "/" 2012-01-02T08:02:53+00:00 Mike Frysinger vapier@gentoo.org 2012-01-02T07:43:37+00:00 97774e90d694f802ff0cfbf15687af77c6f7239e If people use an interp path such as "ld.so", then there is no "/" found, and we end up dereferencing a NULL pointer. Simplify the logic by having a relative interp path like that be the same as "" (which the code later on interprets as $PWD). While we're here, document some of the nuances of this code.

libdl: rudimentary locking for dlopen/dlsym/dlclose 2011-12-22T09:35:35+00:00 Timo Teräs timo.teras@iki.fi 2011-03-24T11:27:36+00:00 f69319d5a7d3a3ccb46b28ee2b0fd9053c6415ac This implements big-dlfcn lock to allow multithreaded usage of dlopen/dlsym/dlclose. We should really clean up the dl code so we can use more fine grained locking or even RCU where appropriate. But at least we won't crash now.
