# @echo off
#
# The test suite command dispatcher
#
# Available commands:
#
#     0 - Make and install AML tests
#     1 - Run specified set of tests in all enabled modes
#     2 - Compare two multi-results of two runs of tests
#     3 - Print out the names of all the available test cases
#     4 - Calculate the current state of all bugs and report the summary
#         tables
#     5 - Prepare bdemo summary files of one multi-results directory for all
#         modes
#     6 - Concatenate bdemo summary files of two multi-results
#
# Notations:
#
#     ASL      - iASL compiler
#     acpiexec - AcpiExec utility
#     acpibin  - AcpiBin utility
#     ASLTSDIR - pathname of root directory of aslts test suite
#
# External definitions required for particular command:
#
#     0 - ASLTSDIR, ASL
#     1 - ASLTSDIR, acpiexec, acpibin
#     2 - ASLTSDIR
#     3 - none
#     4 - ASLTSDIR
#     5 - ASLTSDIR
#     6 - ASLTSDIR
#
# Other:
#   Make sure that "." (current directory) is in your default search path.
#   If necessary, convert all scripts in the aslts/bin directory to unix
#   line endings:
#       d2u aslts/bin/*
#
# Concepts:
#
#     run -   execution of the specified set of tests
#             for one particular enabled mode
#
#     multi-run - execution of the specified set of tests
#                 for all the enabled modes
#
#     multi-result (directory) - directory in RESULTS one containing
#                                all results of one multi-run
#
#     root directory of results - aslts/tmp/RESULTS
#     root directory of aslts - aslts
#
# REMEMBER (To-Be-Done items)
#
#  1. Dont forget to add testing of aml/nopt mode.
#  2. Do make-install till the first error automatically
#  3. Not implemented yet though announced in Usage:
#     - "Do 1 [n32 [n64 [s32 [s64]]]] [<test_case_name> [<test_case_name> [...]]]"
#     - "Make-install all the test cases of the specified test collections"
#     - ...
#  4. Add checking of presence of "Large reference count" message in logs
