The first release candidate for GCC 12.1 is available from https://gcc.gnu.org/pub/gcc/snapshots/12.1.0-RC-20220429/ ftp://gcc.gnu.org/pub/gcc/snapshots/12.1.0-RC-20220429/
and shortly its mirrors. It has been generated from git commit r12-8321-g621650f64fb667. I have so far bootstrapped and tested the release candidate on x86_64-linux. Please test it and report any issues to bugzilla. If all goes well, I'd like to release 12.1 on Friday, May 6th.
