AArch64 build fails surprisingly close to the end (building sys0.o) #10791

Needed system libunwind to pick up aarch64 patches post-1.1 release but applied to the Ubuntu repository. Needed OpenBLAS-develop to pick up this build fix.

Anyone know what LLVM is telling me we've done wrong, here?

The text was updated successfully, but these errors were encountered:

pao · 2015-04-10T23:43:04Z

Imma try this with a newer LLVM and see what happens.

pao · 2015-04-11T01:13:25Z

Same error with LLVM 3.6.0.

I missed this earlier, but:

I also missed mentioning that you do need a small patch to Make.inc to define aarch64 as "not x86":

vtjnash · 2015-05-26T22:35:51Z

interesting, this seems to be the first ARM chip that has been attempted that does not have VFP. that means calling convention is probably correct.

pao · 2015-05-27T01:35:40Z

VFPv3/v4 is apparently pulled into the main instruction set, and NEON is replaced by AdvancedSIMD. I'm not sure why it isn't listed in cpuinfo, though.

Quoting http://people.linaro.org/~rikuvoipio/aarch64-talk/#/17: "VFP/SIMD mandatory - no soft float ABI"

ViralBShah · 2015-07-19T04:02:27Z

With the new updates on using the VFP2 calling convention by default, I wonder if this works now.

pao · 2015-07-19T14:11:32Z

Good question; I'll see what I can do.

ViralBShah · 2015-07-25T15:41:31Z

Bump. Closing, but reopen if still breaking.

pao · 2015-07-25T20:10:35Z

What? The close is obviously premature.

pao · 2015-07-25T20:44:44Z

OpenBLAS doesn't build anymore. Yay.

pao · 2015-07-25T20:51:30Z

Switching to system BLAS/LAPACK, looks like the same assertion:

Keno · 2015-07-25T22:09:53Z

Can you try with llvm-svn, this may potentially be fixed there as part of my effort to improve GOT relocations. If not, I'll need to take a look at some point.

pao · 2015-07-25T23:32:17Z

Sure thing.

pao · 2015-07-26T01:47:47Z

Do we build at all on SVN right now?

Not anymore apparently. LLVM APIs changed again. Should be straightforward fix, but I'm not currently in a position to do & test it.

pao · 2015-07-26T02:09:46Z

No problem.

tkelman · 2015-07-26T04:09:39Z

You can try the release_37 branch of LLVM which should have fewer API changes on it.

ViralBShah · 2015-07-26T05:18:43Z

@pao Glad that my premature closing helped revisit the current status.

pao · 2015-07-26T14:13:47Z

A bump would have done the same.

ViralBShah · 2015-07-26T14:22:27Z

Sure. My bad.

And making the suggested changes in codegen.cpp, we get back to:

This allows the build to proceed for AArch64 (mentioned in #10791) and others. (cherry picked from commit f244fb6) ref #13558

yuyichao · 2015-12-30T19:22:47Z

Is this an issue on LLVM 3.7. I'm able to get a REPL on AArch64 (ArchLinuxARM) with system LLVM 3.7.0 after applying #14511 and #14500 .

yuyichao · 2016-01-06T01:44:10Z

@pao could you please confirm if this is still an issue for you on the LLVM 3.7.0 or 3.7.1 release? Given that I'm able to get all tests pass on AArch64 apart from libunwind and blas bugs, it's likely that this is fixed before LLVM 3.7.0 is released.

Will close in a few days.

pao · 2016-01-06T19:29:18Z

Quite possible that it would work. I don't have my tablet rooted at the moment, and don't think I'll get around to it in the "a few days" timeframe--but I think your success is probably sufficient to close this.

tomaklutfu · 2016-01-06T19:51:36Z

Hi. I may have similar issue detailed in the link using LLVM 3.7.0. I added a Make.user file with LLVM=3.7.1 but it still builds LLVM 3.7.0. If not related sorry for the noise. https://groups.google.com/forum/m/#!topic/julia-users/NO6Lox7r_Xc

tkelman · 2016-01-06T19:56:59Z

probably need to add override to fix the arm setting

yuyichao · 2016-01-06T19:58:16Z

Your screenshot suggest that you are building for a 32bit ARM so it's unrelated to this issue. In additional to the override, you also need to clear the old build so that it builds a new one.

eschnett · 2016-01-06T21:58:46Z

It's LLVM_VER=3.7.1 (with a _VER suffix).

Thanks all. Yes, I mean LLVM_VER. Issue was 'override' . I'll try building again.
