# Utility for scanning compiler result, invoked via dg-final.

# is non-zero, or it is not present and POSITIVE is zero, the test
# passes. The ORIG_ARGS is the list of arguments provided by dg-final
# to scan-assembler. The first element in ORIG_ARGS is the regular
# expression to look for in the file. The second element, if present,
# is a DejaGNU target selector.
