[cfe-dev] XFAIL and XTARGET

[John Thompson]

How are XFAIL and XTARGET supposed to work in a test?

It would be nice if these were documented on the Testing Infrustructure
page.

In looking at the TestRunner.py file, it seems that you should be able to
put something this this in a test to tell it that the test is expected to
fail on Windows:

// XFAIL: i686-pc-win32,x86_64-pc-win32

 But it seems that regardless of what I put after XFAIL, the test comes out
as an expected failure if the test fails, or an unexpected pass if the test
passes.  I've been bouncing between Linux and Windows trying different
things.  It seems that only "// XFAIL" is currently used.

I don't know Python enough to really understand what should be happening.

Basically, the Driver/hello.c test doesn't pass on Windows.  I though if I
put MinGW gcc in the PATH it might pass, but I get the following errors from
just running the compile command line:
