We are going to need to speed up more and more tests, and coding directly with libpthread for that can be tedious and bug-prone. So I devised an implementation for the worker threads design pattern instead, and used it to speed up some tests. * include/Makefile.am: Add the new abg-workers.h to source distribution. * include/abg-workers.h: New file. * src/Makefile.am: Add the new abg-worker.cc to source distribution. * src/abg-workers.cc: New file. * tests/test-utils.cc: Update copyright. Make get_src_dir() and get_build_dir() return a const char*, as opposed to returning a string. Make that const char reside in thread local storage, so that two concurrent threads can safely call these functions in parallel, without any race. * tests/test-utils.h: Make get_src_dir() and get_build_dir() return a const char*, as opposed to returning a string. * tests/test-abicompat.cc: Update copyright. Adjust for get_src_dir() and get_build_dir() change. * tests/test-abidiff.cc: Likewise. * tests/test-alt-dwarf-file.cc: Likewise. * tests/test-core-diff.cc: Likewise. * tests/test-diff-dwarf-abixml.cc: Likewise. * tests/test-diff-dwarf.cc: Likewise. * tests/test-diff-pkg.cc: Likewise. * tests/test-diff-suppr.cc: Likewise. * tests/test-lookup-syms.cc: Likewise. * tests/test-read-dwarf.cc: Likewise. * tests/test-read-write.cc: Likewise. * tests/test-types-stability.cc: Likewise. Use the new task queue type to run these tests in parallel. * tests/test-diff-filter.cc: Likewise. Signed-off-by: Dodji Seketeli <dodji@redhat.com>
