Package: rustc Followup-For: Bug #973414 X-Debbugs-Cc: fierel...@gmail.com After a few false starts, I've built libstd-rust-dev:i386 targeting i686 in the way I'd expected (and to clarify: the interpretation I'm using is to match Debian's baseline and a strict-ish reading of what P6 / i686 was when originally specified).
Editing the 'd-rustc-i686-baseline.patch'[1] to specify "i686" instead of the current "pentiumpro" achieved the result I was looking for: absence of NOPL in the libstd libraries included when users compile statically-linked Rust code. I'll double-check the results soon, and go back to see how that result affects the original bugreport here. My hope is that it helps to verify that the rustc target spec is where we should be looking, but further work may be required. Caveats / todo items: * Check that "i686" is a valid CPU (not architecture) target * Ideally, test this on relevant hardware (non-NOPL, non-SSE2?) Apologies, Fierelier - I didn't see your update until after these results arrived. Your links look relevant though, yep. I _think_ Debian has patched both those locations; I'll check in detail within the next day or two.
