[ http://issues.apache.org/jira/browse/DERBY-921?page=all ] Daniel John Debrunner closed DERBY-921: ---------------------------------------
> Support 32bit branch offsets for conditional logic in generated code. > --------------------------------------------------------------------- > > Key: DERBY-921 > URL: http://issues.apache.org/jira/browse/DERBY-921 > Project: Derby > Type: Sub-task > Components: Services, SQL > Reporter: Daniel John Debrunner > Assignee: Daniel John Debrunner > Priority: Minor > Fix For: 10.2.0.0 > > Conditionals in generated code (MethodBuilder.conditionalIf and > conditionalIfNull) generate code that only supports 16 bit jump offsets for > the branch opcode (e.g. IFNONNULL) or the GOTO opcode. Earlier code now > detects the offset being larger than 32767. > The JVM supports a 32bit jump offset instruction, GOTO_W, this can be used to > support jump offsets that are bigger than 16bits (32767) for both the branch > opcode > and the GOTO instruction. > This allow increasing the number of logical operators as seen in the query in > the largeCodeGen test. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
