[jira] Created: (HARMONY-5267) [drlvm][jit]SpillGen makes
unnecessary spills and produces incorrect code
[drlvm][jit]SpillGen makes unnecessary spills and produces incorrect code
-------------------------------------------------------------------------
Key: HARMONY-5267
URL: https://issues.apache.org/jira/browse/HARMONY-5267
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: Linux/Windows EM64T
r600470
Reporter: Yuri Dolgov
Priority: Critical
SpillGen can make unnecessary spills in case if the last instruction in basic block is jump. It also can generate incorrect code
in this case (place 2 operands on single register).
To reporduce this make the following steps:
1. Download Oracle Database 10g 10.1.0.5 JDBC Drivers (particulary ojdbc14.jar ) from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc101040.html
2. Compile and run the test attached (sql1.java) java -cp ojdbc14.jar oracle.jdbc.driver.sql1
