Thanks - if that's unblocked you, great!

@tmsriram could you check on this? I'm surprised this test isn't failing - I 
can't see any CHECK lines for the "ERROR" prefix used by the error test (& 
FileCheck usually fails if it finds no relevant CHECK lines... so I'm not sure 
what's happening there).

Also: I'd expect a failing compilation not to write the file out? (I'd expect 
it to be writing to a temporary file, then moving the file into position once 
the compilation has finished successfully, so there's never a half-written 
file, etc - in case the compiler crashes) so I wonder what's going on here. 
Could you check what the behavior is/why it's trying to write a file even when 
there's an error? (I could be wrong on my assumptions/understanding here - 
perhaps this is true of other error paths too, that they do try to write the 
output file and maybe delete it after instead (though that wouldn't be 
crash-resilient))
