S390x inline asm This adds register definitions and constraint codes for the s390x general and floating point registers necessary for fixing #85931; as well as a few tests. Further testing is needed, but I am a little unsure of what specific tests should be added to `src/test/assembly/asm/s390x.rs` to address this.
rustc_target contains some very low-level details that are
specific to different compilation targets and so forth.
