[drlvm][jit] Incorrect string comparison
----------------------------------------
Key: HARMONY-5067
URL: https://issues.apache.org/jira/browse/HARMONY-5067
Project: Harmony
Issue Type: Bug

Environment: windows32
Reporter: Evgeniya Maenkova
The test mentioned below produces incorrect resuls starting from some iteration(r591816), works fine with interpreter. This bug isn;t reproducible on, say, r572955.

[jira] Commented: (HARMONY-5067) [drlvm][jit] Incorrect string
comparison
Posted by "Dmitry Pronichkin (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-5067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12540406 ]
Dmitry Pronichkin commented on HARMONY-5067:
--------------------------------------------
The problem is in result operand creation when current compared characters are not equal.
Current code does following actions:
mov si,word ptr [esi]
sub si,word ptr [edi]
movsx eax,si
where esi, edi - positions of current compared symbols, eax - result.
So there will be a mistake while comparing, for example, 0xFFFF and 0x0042 (the result will be negative).
My opinion is to replace the code with smth like this:
movzx eax,word ptr [esi]
sub eax,word ptr [edi]
This conversion from 16bit to 32bit result would be correct.

[jira] Commented: (HARMONY-5067) [drlvm][jit] Incorrect string
comparison
Posted by "Dmitry Pronichkin (JIRA)" <ji...@apache.org>.

Dmitry Pronichkin commented on HARMONY-5067:
--------------------------------------------
Excuse me for a mistake:
actually, SUB instruction sign extends operands too. So we need to manually zero extend second symbol. Overall:
movzx eax,word ptr [esi]
movzx esi,word ptr [edi]
sub eax, esi

[jira] Updated: (HARMONY-5067) [drlvm][jit] Incorrect string
comparison
Posted by "George Timoshenko (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-5067?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
George Timoshenko updated HARMONY-5067:
---------------------------------------
Attachment: Test_2.java
I made a smaller test.
the bug is reproducible when String_compareTo optimization is turned on.
To disable it use:
-XX:jit.arg.String_compareTo_as_magic=false
