Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hjl.tools at gmail dot com, | |redi at gcc dot gnu.org --- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> --- HJ, is what libstdc++ does "unreasonable" (it uses rdseed by default if available) and could it do better? Can you reproduce the issue? The docs quoted by Andrew suggest that libstdc++ should, when retries are not enough, fall back to another method.
