GCC 10.3 Compiler Released With AMD Zen 3 Tuning Backported, Nearly 200 Bug Fixes

GCC 10.3 is out today as the latest stable release of the GNU Compiler Collection, weeks ahead of the GCC 11.1 feature release as the first stable version of GCC 11.

GCC 10.3 back-ports various fixes to the GCC 10 stable series, which was minted last year. The brief release announcement for the GCC 10.3 compiler notes 178 bug fixes over the GCC 10.2 release from a half-year ago.

GCC 10.3 itself isn't too notable on the changes front in just being a bug-fix point release but it did see the AMD Zen 3 "znver3" tuning back-ported in its initial form.

More benchmarks of GCC 10 vs. GCC 11 coming up soon on Phoronix.
