5 | # Run GAS and check that it emits the desired warning for the test case. | |
6 | # Arguments: | |
7 | # file -- name of the test case to assemble. | |
8 | # testname -- a string describing the test. | |
9 | # warnpattern -- a regular expression, suitable for use by the Tcl | |
10 | # regexp command, to decide if the warning string was emitted by | |
11 | # the assembler to stderr. | |
