Hi, I'm building gollvm with both gollvm and LLVM on the latest commit.

It fails and the error reads:

[..]/llvm-project/llvm/tools/gollvm/passes/GoNilChecks.cpp:363:23: error: ‘NoAlias’ was not declared in this scope
if (AAResult != NoAlias)
^~~~~~~
[..]/llvm-project/llvm/tools/gollvm/passes/GoNilChecks.cpp:363:23: note: suggested alternative: ‘AR_NoAlias’

Can you guys check? Sorry if I'm spamming about gollvm lately.

Thanks!

Thanks for reporting. I'll look into sending a CL.

Cheers, Than

OK, I checked in https://go-review.googlesource.com/c/gollvm/+/310069, should be resolved now. Thanks for reporting.

Thanks,

I see it's hard to keep syncing with LLVM. They have new commits every minute

Hi Ian,

My project is currently running on LLVM10.

If I want to use gollvm, do I just have to upgrade to the latest commits?

Thanks

Hi again,

Not quite sure what you are asking--

If you want to generated LLVM bitcode and then use that with your version 10 llvm tools, then you'll either need to build a version-10 compatible gollvm, or you'll need to upgrade the LLVM used by your tools/project.

You can try building a V10-compatible gollvm by checking out old versions of the various git repos in your work area. These sha's should give you a working V10 gollvm:

# This is the llvm 10.0.1 final git tag:
LLVM: ef32c611aa214dea855364efd7ba451ec5ec3f74

gollvm: ad0491f483d17893a2439bdb63d0f94124965549

gofrontend: 85641a0f26061f7c98db42a2adb3250c07ce504e

libffi: 737d4faa00d681b4c758057f67e1a02d813d01c2

libbacktrace: 5a99ff7fed66b8ea8f09c9805c138524a7035ece
