The first release candidate for GCC 9.4 is available from
https://sourceware.org/pub/gcc/snapshots/9.4.0-RC-20210519/ and shortly its mirrors. It has been generated from git commit 8091c46cf736124a106922ddfd1fdb99f33b0241. I have so far bootstrapped and tested the release candidate on {x86_64,i586,aarch64,ppc64le,s390x,riscv64,ppc,ppc64,armv7l}-linux. Please test it and report any issues to bugzilla. If all goes well I'd like to release 9.4 on Friday, June 28th.
