The first release candidate for GCC 11.1 is available from https://gcc.gnu.org/pub/gcc/snapshots/11.1.0-RC-20210420/ ftp://gcc.gnu.org/pub/gcc/snapshots/11.1.0-RC-20210420
and shortly its mirrors. It has been generated from git revision r11-8265-g246abba01f302eb453475b650ba839ec905be76d. I have so far bootstrapped and tested the release candidate on x86_64-linux and i686-linux. Please test it and report any issues to bugzilla. If all goes well, I'd like to release 11.1 on Tuesday, April 27th.
