33 Usage: gdb_buildall.sh [ <options> ... ] <srcdir> <builddir>
37 --bfd64 Enable 64-bit BFD.
38 --clean Delete build directory after check.
39 -e <regexp> Regular expression for selecting the targets to build.
40 --force Force rebuild.
41 -j <makejobs> Run <makejobs> in parallel. Passed to make.
42 On a single cpu machine, 2 is recommended.
44 <srcdir> Source code directory.
45 <builddir> Build directory.
