Description
|
The test
closed/compiler/6512111/CorruptFinalLong.java
started failing with HS14-b04 in "-client -Xmixed" mode on linux-i586, windows-i586, solaris-i586. HS14-b03 does not have this problem. It looks like a reincarnation of 6512111.
To reproduce:
$ ssh vm-v20z-34.sfbay
$ cd /tmp
$ cp /net/sqenfs-1.sfbay/export1/comp/vm/testbase/jtreg/7/HS_REGRESSION/test/closed/compiler/6512111/CorruptFinalLong.java .
$ /net/sqenfs-1.sfbay/export1/comp/vm/jdk/hsx/14/pit/b04/product/linux-i586/bin/javac CorruptFinalLong.java
$ /net/sqenfs-1.sfbay/export1/comp/vm/jdk/hsx/14/pit/b04/product/linux-i586/bin/java -client -Xmixed CorruptFinalLong

The changes to merge the assemblers and make a 64-bit C1 incorrectly
changed the logic in stack2stack, resuting incorrect long moves. The
fix is to restore the original code.
