The first release candidate for GCC 12.3 is available from https://gcc.gnu.org/pub/gcc/snapshots/12.3-RC-20230502/
and shortly its mirrors. It has been generated from git commit r12-9504-ga4f604fa194e0c. I have so far bootstrapped and tested the release candidate on x86_64-linux-gnu. Please test it and report any issues to bugzilla. If all goes well, we'd like to release GCCC 12.3 on Tuesday, May 9th.
