#
# Test programs for the RAID library
#
# Primary Targets:
# all          - Builds all test and utility binaries (fulltest, speedtest, selftest, invtest, mktables).
# clean        - Removes all temporary object files, build artifacts, and coverage metadata.
# distclean    - Runs clean and deletes all compiled test executables.
#
# Test & Diagnostic Binaries:
# selftest     - Runs the same verification and speed tests executed at module initialization.
# speedtest    - Runs a comprehensive performance/throughput benchmark suite.
# fulltest     - Runs an exhaustive test suite verifying all built-in RAID functions.
# invtest      - Runs an extensive matrix inversion test on all 377,342,351,231
#                possible square submatrices of the Cauchy matrix used.
#
# Test Automation & Emulation:
# test         - Automated test runner that executes ./selftest, ./speedtest, and ./fulltest.
# covtest      - Executes a code coverage test using lcov/genhtml to generate HTML reports.
# sdecovtest   - Runs an extensive coverage test using the Intel SDE emulator across 
#                multiple CPU architectures (Prescott, Merom, Nehalem, Haswell, Skylake, Ice Lake).
# sde          - Runs selftest, speedtest, and fulltest explicitly on the Ice Lake simulator.
