test-tool   [plain text]

#!/bin/sh
# This script automatically test the given tool with the tool's test cases,
# reporting anything of interest.

# exits with 1 if there is nothing of interest
# exits with 0 if there is something interesting
# exits with 2 if an error occurred

# Syntax: test-tool [-expectedpass] [-keepoutput] [-noupdate] g++|gcc|gdb|...
#
# -expectedpass: Turn XFAIL into "pass", XPASS into "fail".
#		 The default is XFAIL->fail, XPASS->pass.
# -keepoutput: Save "make check" output in test-$tool.log.
# -noupdate: Don't update log files.

# Limitations, don't run this multiple times in one day, unless the -noupdate
# flag is given.
