Richard Biener of SUSE issued a status report today on GCC 8.0.1 ahead of the GCC 8.1 stable release expected in the weeks ahead.
The GCC 8 code-base remains open for regression and documentation fixes. Per the annual GNU Compiler Collection release process, they usually hit their first release candidate by April. But for GCC 8 they still have a number of open regressions that may push back their RC1 hopes for mid-April.
