InstCodeSelector::tau_arrayLen generates non-serilizable rt-dependent
immediate
[drlvm][jit][opt] InstCodeSelector::tau_arrayLen generates non-serilizable rt-dependent immediate
-------------------------------------------------------------------------------------------------
Key: HARMONY-2728
URL: http://issues.apache.org/jira/browse/HARMONY-2728
Project: Harmony
Issue Type: Bug
Components: DRLVM
Reporter: Nikolay Sidelnikov
Priority: Minor
Function InstCodeSelector::tau_arrayLen (Ia32InstCodeSelector.cpp) contains the
following code
Opnd * offset=irManager.newImmOpnd(typeManager.getInt32Type(),
arrayType->getArrayLengthOffset());
which discords with the general Jitrino policy to keep (until code emission)
all runtime-dependent immediates as operands with 'runtimeInfo' field set to a
value discribing the immediate in serializable form.

[jira] Closed: (HARMONY-2728) [drlvm][jit][opt]
InstCodeSelector::tau_arrayLen generates non-serilizable rt-dependent
immediate

Mikhail Fursov closed HARMONY-2728.
-----------------------------------
Resolution: Won't Fix
Closing this issue as "Won't Fix"
Reason: Yes, most of runtime infos are resolved in "emitter" pass. However there is nothing wrong to resolve offsets of 'array length' field in LIR selector and allow optimizations like 'cafl' optimize it.
