Hi, Than
Thanks a lot! It is working now.
go version is "unknown" but it is okay.

Hi,
While running the latest commit of gollvm (with latest commit of
gofrontend, libbacktrace, libffi) with LLVM13 (commit llvmorg-13.0.0-rc3),
I encountered this error:
llvm-project/build13/tools/gollvm/libgo/version.go:9:6: error: redefinition
of 'ArchFamilyType'
llvm-project/llvm/tools/gol
Hi,
While running the latest commit of gollvm (with latest commit of
gofrontend, libbacktrace, libffi) with LLVM13, I encountered this error:
llvm-project/build13/tools/gollvm/libgo/version.go:9:6: error: redefinition
of 'ArchFamilyType'
llvm-project/llvm/tools/gollvm/gofrontend/libgo/go/runtime
So, I figured out this inline asm ends with a "checksum" then ".text".
I think I can remove inline asm before this ".text" and keep the rest since
it might be useful.
Please correct me if I'm wrong.
Thanks for your support!

Also, from what I understand, if noone imports my package, I can also
remove the "module asm" lines at the start. Is that right?

A Helloworld written in C++ is around 75 lines in LLVM IR.
However, a Helloworld written in Golang compiled with gollvm is around
900/1000 lines of .ll file. I produced the LLVM IR with instructions from
https://go.googlesource.com/gollvm/
I'm using LLVM11, so, older compatible commit of gollvm

Hi, I am upgrading to LLVM11, how can I run LLVM11-compatible gollvm? What
are the commits of LLVM, gollvm and related libs should I checkout?
Thanks!

Hi, I'm building a tool to analyze the LLVM bitcode of some Go code with
gollvm.
We are currently running LLVM10. We will migrate to LLVM11/12 but not sure
when.
I followed Than's instruction to build LLVM10-compatible gollvm from
https://groups.google.com/g/golang-nuts/c/dMZ7vk_Rjzw/m/b1zYDOxLA

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, 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)

ere a manual on which version of LLVM should I build gollvm with and
which version is the bitcode that -emit-llvm produces?

Hi,
I'm following this page https://go.googlesource.com/gollvm to compile Go
code the LLVM way.
I'm at the step "How do I see the LLVM IR generated by gollvm?" of the
page. I'm doing exactly as the instruction. Gollvm produces a .ll file but
the file has bad syntax. Running llvm-as (or llc, lli)

cause the same error as before. This file builds and runs fine with my
normal Go but gives that error with Gollvm. If I do not include unix,
Gollvm does work though.
What do you suggest?

Hi Ian,
"gold --version" gives me "GNU gold (GNU Binutils for Ubuntu 2.34) 1.16"
"go list -m all" does list the module golang.org/x/sys. Does it help with
the case?
Thanks for your help.

Is there still a bug or is it on my end?

Looks like the same error as this one
https://github.com/golang/go/issues/44861 . I'm just looking at their first
comment on github, ignoring the lengthy bug report.

Hi, I'm a newbie.
I built and installed gollvm with instructions from
https://go.googlesource.com/gollvm
The build/installation was successful but it cannot run after installing.
The step on the page "Using an installed copy of gollvm" is where the error
happens. Running "go" gives me this error:
