# INPUT:
# btest <target> <source> <prefix> <state> <build>
# TARGET is the target triplet.  It should be the same one
# as used in constructing PREFIX.
TARGET=$1
# SOURCE is the directory containing the toplevel configure.
SOURCE=$2

# PREFIX is the directory for the --prefix option to configure.
#   For cross compilers, it needs to contain header files,
#   libraries, and binutils.  PATH should probably include
#   $PREFIX/bin.  
PREFIX=$3
# This script also needs to include the GDB testsuite in
#   $PREFIX/share/gdb-testsuite.
GDB_TESTSUITE=$PREFIX/share/gdb-testsuite

# STATE is where the tester maintains its internal state,
#   described below.
STATE=$4

# BUILD is a temporary directory that this script will
#   delete and recreate, containing the build tree.
BUILD=$5

# you also probably need to set these variables:
# PATH: should contain a native gcc, and a cross gdb.
# DEJAGNU: should point to a site.exp suitable for testing
#   the compiler and debugger.


# OUTPUT: in $RESULT, one of the following keywords:
#   error       the script failed due to
#               a misconfiguration or resource limitation
#   build       the build failed
#   regress-<n> the build succeeded, but there were <n>
#               testsuite regressions, listed in $REGRESS
#   pass        build succeeded and there were no regressions
RESULT=$STATE/RESULT
# in BUILD_LOG, the output of the build
BUILD_LOG=$STATE/build_log
# in FAILED, a list of failing testcases

# in PASSES, the list of testcases we expect to pass

# in REGRESS, a list of testcases we expected to pass but that failed
REGRESS=$STATE/regress
