   4 # This script computes the various flags needed to run GNU C++ testsuites
   5 # (compiler specific as well as library specific).  It is based on
   6 # the file ./mkcheck.in, which in the long will be removed in favor of a
   7 # DejaGnu-based framework.

  13 # Synopsis
  14 #   * tests_flags --compiler build-dir src-dir
  15 #
  16 #      Returns a space-separated list of flags needed to run front-end
  17 #      specific tests.
  18 #
  19 #   * tests_flags --built-library build-dir src-dir
  20 #   * tests_flags --installed-library build-dir src-dir install-dir
  21 #
  22 #      Returns a colon-separated list of space-separated list of flags,
  23 #      needed to run library specific tests,
  24 #      BUILD_DIR:SRC_DIR:PREFIX_DIR:CXX:CXXFLAGS:INCLUDES:LIBS
  25 #      the meaning of which is as follows:
  26 #        BUILD_DIR   libstdc++-v3 build-dir
  27 #        SRC_DIR     libstdc++-v3 src-dir
  28 #        PREFIX_DIR  install-dir (meaningful only with --installed-library)
  29 #        CXX         which C++ compiler is being used
  30 #        CXXFLAGS    special flags to pass to g++
  31 #        INCLUDES    paths to headers
  32 #        LIBS        flags to pass to the linker
