RFR(L): 8205044: [lworld] Interpreter and compiler support for acmp with value type operands

[Roland Westrelin]

Hi Tobias,

> http://cr.openjdk.java.net/~thartmann/8205044/webrev.00/

In compile.cpp:

4652     // Return constant false because one operand is a non-null value type
4653     return new CmpINode(phase->intcon(0), phase->intcon(1));

there must be a better way to return always false.

How is the change in callGenerator.cpp related to acmp?

Roland.
