# Repeatedly stop building until successive layers, and run all tests built,
# while checking for undefined behavior using both UBSan and Valgrind.
#
# Requires Linux.
#
# Usage:
#   Test all layers:
#     test_layers
#   Test non-app layers after x:
#     test_layers x
#   Test layers after x and until y (inclusive):
#     test_layers x y
#   Test all layers for a specific app:
#     test_layers app
