make check fails when using gcc 7.3

[mrader1248]

I have successfully built and tested BLIS with icc (2015) using make check. However, when I use gcc 7.3 together with the binutils 2.30 (on the same machine), some tests fail. As far as I can tell, only real test cases are affected. I ran configure with the options --enable-shared --enable-static --enable-blas --enable-cblas. Attached to this message you can find the blocks of output.testsuite where test cases fail.

As gcc 7.3 is rather new, I also tested gcc 7.2 -- same problem.

3. Your complete configure line and output?
4. What version/git commit of BLIS you are using?

[devinamatthews]

OK, I can replicate this and will look into it.

[mrader1248]

Thank you very much for your quick response!

[devinamatthews]

No problem, thanks for the bug report. Look like a doozy!

[fgvanzee]

My default assumption is that this is a compiler bug, given that so many compilers before/other than gcc 7.2/7.3 do not show any problems. (Granted, it's always possible we're using some sloppy syntax that is no longer forgiven in those versions.)

@devinamatthews Thanks for looking into this.

[devinamatthews]

@mrader1248 we've found the problem and I believe @fgvanzee is working on a fix (unless you want me to do it).

[fgvanzee]

@devinamatthews I'll commit a fix to the issue @mrader1248 pointed out. Thanks for your help identifying the root cause.

[fgvanzee]

@mrader1248 Please try e2192a8 and let us know if the test failures persist or go away. Thanks for your feedback.

[mrader1248]

Thank you very much for your great help! Now everything works as expected. Looking forward to benchmarking.
Just for curiosity's sake: Why is the zen code needed for the haswell config?
Will this commit be included into the latest version?

[fgvanzee]

@mrader1248 Glad we were able to fix your problem. (Devin tracked down the issue quickly.)

Just for curiosity's sake: Why is the zen code needed for the haswell config?

While the Haswell, Broadwell, Skylake, Kabylake, Coffeelake, and Zen microarchitectures are all distinct, they actually share roughly the same instruction set (at least for our purposes) and number of vector registers. The net effect of this is that we can recycle kernel code across those microarchitectures, even if each of those systems would ideally use different cache blocksizes (which can be encoded in the individual sub-configurations, e.g. haswell vs. zen) .

So, we could have labeled the kernels as haswell and imported them into the zen configuration, and the result would have been the same.

Will this commit be included into the latest version?

I'm not sure if I understand the question. If you are asking if this commit will be merged into master, the answer is absolutely. (In fact, I just did.)

If you are asking if this commit will make it into the next version number, the answer is the same (yes). Please note that when we bump the version number is somewhat arbitrary. But rest assured that there is nothing special about using a commit that has a fresh version number; it's just an arbitrary milestone. We are constantly making improvements, in part thanks to great feedback from contributors such as yourself, and so we strongly encourage our users, especially those engaged with developers, to use the head commit of the master (or dev) branch, rather than the latest tagged version.

Thank you for the clarification.

Yes, to be 'git-precise': I wanted to know whether this commit will be merged into master, such that I have to work with a specific commit no longer.

Thank you all again for your help!
