[jira] Created: (HARMONY-5595) [drlvm][jitrino]Difference in
bc-mapping after translator
[drlvm][jitrino]Difference in bc-mapping after translator
---------------------------------------------------------
Key: HARMONY-5595
URL: https://issues.apache.org/jira/browse/HARMONY-5595
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: All
Reporter: Nikolay Kurtov
Discussion on mailing list:
http://www.mail-archive.com/dev@harmony.apache.org/msg13158.html
I compiled the same class with JET and OPT, and found a difference in bytecode-mapping
One of branches of switch goes to this code:
;; 58) ILOAD_0
;; 59) BIPUSH 45
;; 61) IADD
;; 62) I2B
;; 63) ISTORE_1
....
So, after the recompilation by OPT, the block should begin from bcOffset 58
In OPT after translator I found in irdump the following block
Block L5:
Predecessors: ENTRY_L0
Successors: L8
I5:L5: bcmap:59
I34:ldci4 #45 -) t14:int32
I35:add t1, t14 -) t15:int32
I36:convi1 t15 -) t16:int32
I37:stvar t16 -) v1:int32
....
The block begins from bcOffset 59
I consider these values in JET and OPT should be equal.
