Adding A Test Case To A Test Suite.

There are two slightly different ways to add a test case. One is to add the test case to an existing directory. The other is to create a new directory to hold your test. The existing test directories represent several styles of testing, all of which are slightly different; examine the directories for the tool of interest to see which (if any) is most suitable.

Adding a GCC test can be very simple: just add the C code to any directory beginning with gcc. and it runs on the next
runtest --tool
      gcc
.

To add a test to GDB, first add any source code you will need to the test directory. Then you can either create a new expect file, or add your test to an existing one (any file with a .exp suffix). Creating a new .exp file is probably a better idea if the test is significantly different from existing tests. Adding it as a separate file also makes upgrading easier. If the C code has to be already compiled before the test will run, then you'll have to add it to the Makefile.in file for that test directory, then run configure and make.

Adding a test by creating a new directory is very similar:
