199: [RFC] initial Cortex-R team r=japaric a=japaric This is a proposal for creating a Cortex-R team. @paoloteti and I will be the initial members. I know pretty much nothing about the Cortex-R but will be working with them starting November; @paoloteti is the real expert here. The following work has been planed for this team (some of it has been done already) - [x] Add more built-in targets to cover existing devices. In rust-lang/rust#53679 we went from 1 target to 4. We now have good coverage of Cortex R4(F) and R5(F) cores. - [x] Move to LLD to remove the dependency on a external linker. Done in rust-lang/rust#53679. - [x] Produce `rust-std` components to not depend on tools like Xargo, which require nightly. Also done in rust-lang/rust#53679. - [ ] Create a `cortex-r` crate (\*) akin to the `cortex-m` crate that provides a safe API to emit arch-specific instructions and to manipulate system registers. - [ ] Create a `cortex-r-rt` crate (\*) akin to the `cortex-m-rt` crate that helps building a minimal `no_std` binary. - [ ] See if we can generate register APIs from the XML files that vendors like TI ship with their IDEs. (\*) Initial work in this area: https://github.com/paoloteti/ti-hercules-bsp @rust-embedded/all please vote on this proposal using [GitHub reviews][approve]. This proposal needs at least 11 approvals to land (/all has 21 members atm).

This is a proposal for creating a Cortex-R team.
@paoloteti and I will be the initial members. I know pretty much nothing about
the Cortex-R but will be working with them starting November; @paoloteti is the
real expert here.
The following work has been planed for this team (some of it has been done
already)
Add more built-in targets to cover existing devices. In
add more Cortex-R targets rust-lang/rust#53679 we went from 1 target to 4. We now have good coverage of
Cortex R4(F) and R5(F) cores.

add more Cortex-R targets rust-lang/rust#53679.

rust-stdcomponents to not depend on tools like Xargo, whichrequire nightly. Also done in add more Cortex-R targets rust-lang/rust#53679.
Create a
cortex-rcrate (*) akin to thecortex-mcrate that providesa safe API to emit arch-specific instructions and to manipulate system
registers.
Create a
cortex-r-rtcrate (*) akin to thecortex-m-rtcrate thathelps building a minimal
no_stdbinary.See if we can generate register APIs from the XML files that vendors like
TI ship with their IDEs.
