I'm experimenting with a new GC at

https://github.com/nordlow/druntime/blob/fastalloc-gc/src/gc/impl/fastalloc/gc.d

in my druntime branch fastalloc-gc.

I've found a way to benchmark it using dmd as outlined at

https://forum.dlang.org/post/zjxycchqrnxplkrlmnsj@forum.dlang.org

but what about rebuilding druntime+phobos with ldc and linking with that specific libphobos.so when compiling my benchmarking app with ldc? Is it possible? If so, what's the preferred way?

LDC has its own forks of druntime and Phobos, with numerous required adaptations. So you'd need to apply your patches to those forks & build the libs (druntime and Phobos are separate libs for LDC), e.g., with the included ldc-build-runtime tool, which makes this painless: https://wiki.dlang.org/Building_LDC_runtime_libraries
The Wiki page also shows how to link those libs instead of the shipped-with ones.

Thanks.
