# This script computes the various flags needed to run GNU C++ testsuites
# (compiler specific as well as library specific). It is based on
# the file ./mkcheck.in, which in the long will be removed in favor of a
# DejaGnu-based framework.
#
# Written by Gabriel Dos Reis <gdr@codesourcery.com>
#
#
# Synopsis
# * tests_flags --compiler build-dir src-dir
#
# Returns a space-separated list of flags needed to run front-end
# specific tests.
#
# * tests_flags --built-library build-dir src-dir
# * tests_flags --installed-library build-dir src-dir install-dir
#
# Returns a colon-separated list of space-separated list of flags,
# needed to run library specific tests,
# BUILD_DIR:SRC_DIR:PREFIX_DIR:CXX:CXXFLAGS:INCLUDES:LIBS
# the meaning of which is as follows:
# BUILD_DIR libstdc++-v3 build-dir
# SRC_DIR libstdc++-v3 src-dir
# PREFIX_DIR install-dir (meaningful only with --installed-library)
# CXX which C++ compiler is being used
# CXXFLAGS special flags to pass to g++
# INCLUDES paths to headers
# LIBS flags to pass to the linker
#
