The first release candidate for GCC 10.4 is available from https://gcc.gnu.org/pub/gcc/snapshots/10.4.0-RC-20220621/ ftp://gcc.gnu.org/pub/gcc/snapshots/10.4.0-RC-20220621/
and shortly its mirrors. It has been generated from git commit r10-10862-g3c390f4ad27c3d79fd1817276a6d3217fd9bfb51. 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 10.4 on Tuesday, June 28th.
