Tim Armstrong updated IMPALA-7923: ---------------------------------- Issue Type: Improvement (was: Bug) > DecimalValue should be marked as packed > --------------------------------------- > > Key: IMPALA-7923 > URL: https://issues.apache.org/jira/browse/IMPALA-7923 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Affects Versions: Impala 3.1.0 > Reporter: Tim Armstrong > Priority: Major > > IMPALA-7473 was a symptom of a more general problem that DecimalValue is not > guaranteed to be aligned by the Impala runtime, but the class is not marked > as packed and, under some circumstances, GCC will emit code for aligned loads > to value_ when value_ is an int128. > Testing helps confirm that the compiler does not emit the problematic loads > in practice, but it would be better to mark the struct as packed. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
