Of ratified RISC-V features defined, this commit adds extensions
satisfying following criteria:
* Formerly a part of the "I" extension and splitted thereafter
(now ratified as "I" + "Zifencei" + "Zicsr" + "Zicntr" + "Zihpm") or
* Dicoverable from newer versions of the Linux kernel and implemented
as a part of std_detect's feature ("Zihintpause").
This is based on the latest ratified ISA Manuals (version 20240411).
Additional (1):
One of those, "Zicsr", is a dependency of many other ISA extensions and
this commit adds correct dependencies to "Zicsr".
Additional (2):
In RISC-V, "G" is an abbreviation of following extensions:
* "I"
* "M"
* "A"
* "F"
* "D"
* "Zicsr" (although implied by "F")
* "Zifencei"
and all RISC-V targets with the "G" abbreviation and targets for Android /
VxWorks are updated accordingly.
Note:
Android will require RVA22 (likely RVA22U64) and some more extensions,
which is a superset of RV64GC. For VxWorks, all BSPs currently distributed
by Wind River are for boards with RV64GC (this commit also updates
riscv32-wrs-vxworks though).

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
