> I get the same problem with [GPL](https://github.com/solana-labs/governance-program-library), tests work with` 1.14.18` but fail with `1.16.1 ` How to run GPL tests? Is running `cargo test` sufficient to reproduce the...

I work on updating platform-tools to rust 1.72. Current plan is to release updated platform-tools by the end of this week, but it may take longer.

Indeed, we already added SubtargetFeature "solana" to the BPF target in llvm. All our llvm changes are enabled only when the feature is enabled by a command line option. I...

This is a good point. Yes the solana forks will be used as buffers for changes/fixes that eventually should be submitted to upstream.

We currently have LTO disabled because with LTO incorrect BPF code is produced in some cases (need investigation and fixing). The default optimization level in our toolchain is O3 (which...

If I remember correctly, running [solana/scripts/build-downstream-projects.sh](https://github.com/solana-labs/solana/blob/master/scripts/build-downstream-projects.sh) should fail on some test if `-C lto=no` is not added to `RUSTFLAGS` environment variable. We automatically add this option in cargo-build-bpf https://github.com/solana-labs/solana/blob/1fae3d24de820069417414b900a7efee9e82ecf7/sdk/cargo-build-bpf/src/main.rs#L518-L527

We had rust standard libraries as a separate repository https://github.com/solana-labs/rust-bpf-sysroot It was difficult to update to new versions of rust. I think it would be better if we maintain the...

If we go on the path of separating std and publishing it on crates.io, rust-std-sbf-solana-solana won't be available for installation via rustup as a component, correct? I guess, it's not...
