Todd Lipcon created HADOOP-9707: ----------------------------------- Summary: Fix register lists for crc32c inline assembly Key: HADOOP-9707 URL: https://issues.apache.org/jira/browse/HADOOP-9707 Project: Hadoop Common Issue Type: Bug Components: util Affects Versions: 3.0.0, 2.1.0-beta Reporter: Todd Lipcon Assignee: Todd Lipcon Priority: Minor
The inline assembly used for the crc32 instructions has an incorrect clobber list: the computed CRC values are "in-out" variables and thus need to use the "matching constraint" syntax in the clobber list. This doesn't seem to cause a problem now in Hadoop, but may break in a different compiler version which allocates registers differently, or may break when the same code is used in another context. -- This message is automatically generated by JIRA.
