It is possible to use various other Programs (or Libraries with a bit of programming) and run them seperately on a test script to check that both programs give the same result. We could compile and run 'crlibm' (and some other programs) _without_ incorporating it's code into gcc and compare the results of the two Programs with each other using 'diff' . Doing the above is useful for _testing_ but ultimatley we should either 'fix' our code to use the default flags (so the math is not broken) _or_ use the flags that I suggested as the defaults and avoid the problem altogether. We could (but do not have to) use a different math Library. The existance of other code that works correctly proves that we could write our own code differently (properly) and have correct results instead of insisting that we can only have a wrong result and that we should accept it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32180
