# Test for error messages when a bad register name, an out of range operand, or

# invalid syntax is used.  Adapted from Ben Elliston's load-hazard testcase.

# Run GAS and check that it emits the desired error for the test case.

# Arguments:

#   file -- name of the test case to assemble.

#   testname -- a string describing the test.

#   warnpattern -- a regular expression, suitable for use by the Tcl

#     regexp command, to decide if the warning string was emitted by

#     the assembler to stderr.
