On a native mips linux machine, we are failing a make check test which
seems like it is supposed to already xfail.
For one, the file test.c does not even exist (it is called test.cpp)
And in the test file there is a line:
XFAIL: powerpc64, s390x, mips, sparc
The script in make check thinks that it passed but clearly it does not.
llvm-cov is returning 0 in this case.
Anybody know about this issue?

The immediate issue her for me is that llvm-cov is clearly failing but it
returns 0.
This causes make check to fail because then it becomes an unexpected pass
because
this test is xfailed for mips.

On a native mips linux machine, we are failing a make check test which
seems like it is supposed to already xfail.
For one, the file test.c does not even exist (it is called test.cpp)
And in the test file there is a line:
XFAIL: powerpc64, s390x, mips, sparc
The script in make check thinks that it passed but clearly it does not.
llvm-cov is returning 0 in this case.
Anybody know about this issue?

I don’t have a mips system, so it’s hard to know what’s going on. The XFAIL may be too broad. As I remember, the intention was to XFAIL big-endian systems. Then again, it does seem like there is a real failure here. I would be happy to work with you to try to get it fixed, but you’ll have to do some debugging to figure out what the problem is.

This test file really has too many tests in it, which makes it confusing to debug failures. Someone (me?) should probably split this into several tests that invoke llvm-cov once each. The use of diff should be replaced with FileCheck as well, so that error messages are clearer. In any case, all of the llvm-cov calls except the read/checksum fail invocations should (and do) return zero on little-endian. I think the only problem here is that the XFAIL line is wrong.

This is obviously a problem.'XFAIL: mips' counts as an XFAIL for all mips targets because lit is checking for substrings (using the 'in' operator) of the target triple and 'mips' is a substring of 'mipsel-...'. I haven't tested this but I think that we need 'XFAIL: mips-, mips64-' to distinguish little/big-endian correctly for MIPS. The relevant code is the isExpectedToFail() function in utils/lit/lit/Test.py.> -----Original Message----- > From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] > On Behalf Of Justin Bogner > Sent: 21 February 2014 08:21 > To: Reed Kotler > Cc: LLVMdev at cs.uiuc.edu > Subject: Re: [LLVMdev] make check issue with llvm-cov > > reed kotler <rkotler at mips.com> writes: > > On a native mips linux machine, we are failing a make check test which > > seems like it is supposed to already xfail. > > I think you're mistaken.
