None other than dejagnu documentation.

I recently tried running the testsuite for i686-pc-linux-gnu and ran 
into a problem due to a change that was made in April.  Try the 
accompanying patch and see if it helps you.

I'm assuming you have set up the DEJAGNU environment variable to point 
to your site.exp file.  What platform are you testing for?  Do you have 
an appropriate baseboards exp for it?

Not sure what you are asking here unless you are referring to the 
site.exp file.

The newlib testsuite is quite small at this point.  A lot of testing of 
newlib is performed by third-party testsuites that exercise both the 
compiler and library together.  If you look at the different newlib.xx 
directories, you'll see what it tests: string functions, iconv, 
multibyte character functions, an hsearch test,  the wctype functions, 
and there is a minor EL/IX test for i686-pc-linux-gnu only.

The best test there IMO is the string test.  A number of platforms 
rewrite the string functions in assembler for speed and they often have 
bugs to sort out.  I have found this test useful in the past for finding 
these kind of bugs.

The libgloss tests are old and I don't know if they even run any more.
