Yes, this is basically correct. >As per my understanding, GC is common for both cases (still I was unbale to find the source code for this GC). The GC is located in the Go runtime, the version incorporated into libgo in gofrontend. See https://go.googlesource.com/gofrontend/+/01cb2b5e69a2d08ef3cc1ea023c22ed9b79f5114/libgo/go/runtime/mgc.go Cheers, Than On Fri, Jul 9, 2021 at 9:16 AM Kavindu Gimhan Zoysa <kavindu...@gmail.com> wrote: > Hi all, > > By looking at the source code, and other mail theads in group, I was able > to understand the sopport of GC by gollvm upto some extend. > > 1.
