TODO Unable to compile PIE

See PIE mode

Notes

go-* library removal

Since making the OpenBSD ports tree work with Go modules, we no longer need go-* libraries.

libc for syscalls

jsing@ is working on a change to make Go use OpenBSD's libc for syscalls.

Last update on it was [2020-01-04 Sat]
The issue for tracking is here: #36435

portgen

[2020-05-14 Thu] Committed the Go portgen bits!

portgen issues

FIXED mod go graph seemingly not displaying all deps
[2020-05-16 Sat] A number of ports with large dependencies seem to need more dependencies than mod go graph shows. For example:
- github.com/gruntwork-io/terragrunt
- github.com/caddyserver/caddy/v2
What's interesting is that things build fine with go build outside of the ports tree.
- This was being caused by not properly getting a list of hard-deps. Switched to calling go list -m all to get a list of modules that are required (need .zip and .mod files).

PIE mode

Around [2020-02-01 Sat] I started working on PIE mode for Go amd64. Here is a diff to enable PIE on OpenBSD.

I got everything working:

It is able to produce binaries.
Tests pass.

However, about 50% of the time binaries produced with it die with a SIGSEGV.

[2020-02-11 Tue] Sent a mail to h@ to see if anyone could help out. Worked a bit with jsing@, interestingly it works fine on single CPU machines.

Race detector

Requires a race_${OS}_${ARCH}.syso file produced via golang.org/x/build/cmd/racebuild.

This tool requires gomote, and possibly some other bits, pulls down Go and LLVM, builds things and poops out a syso file.
For racebuild to work, LLVM compiler-rt/tsan/go and friends need to be updated to work with OpenBSD. Possibly similar to how it was done for NetBSD.
With this diff against LLVM and this diff against Go, I am able to test for race conditions \o/ ! Running main() with -race displays:

DONE Send in the diff to add race to OpenBSD \o/

Submitted!

TODO Plugins

While looking at PIE mode - it seems like it wouldn't be too hard to make plugins work.

CANCELED Update port to be > 1.14

sparc64

There is currently a port of Go to sparc64 available here. It might be usable as a bootstrap for OpenBSD's port.

At the very least it will be a decent starting point.
