From 457e874459ae638145cab6d572e34d48480e39d2 Mon Sep 17 00:00:00 2001 From: Igor Murashkin Date: Thu, 22 Oct 2015 17:37:50 -0700 Subject: lambda: Add support for invoke-interface for boxed innate lambdas Lambda closures created with the 'create-lambda' instruction (termed "innate lambdas") can be turned into an object with 'box-lambda'. This CL enables support for those kinds of lambdas to work with 'invoke-interface' by generating a proxy class for the lambda. Note: MIPS32/64 support not included.
