From c9fcfd02a69170cedcd4cf2e66826f246dff6267 Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Tue, 5 Jan 2021 16:57:30 +0000 Subject: Optimizing: Add debugging output for HInstruction. Allow printing individual instruction and its arguments with the HGraphVisualizer. Arguments are dumped "recursively" (but implemented with a queue instead of actual recursion). For example, printing the Return instruction from the method Main.testLoop17 in 530-checker-lse yields v28 Return [i27] dex_pc:23 loop:none i27 Add [i24,i26] dex_pc:22 loop:none i24 Phi [i5,i15] dex_pc:n/a reg:0 is_catch_phi:false loop:none i5 IntConstant dex_pc:0 1 loop:none i15 IntConstant dex_pc:5 2 loop:none i26 InstanceFieldGet [l6] dex_pc:20 field_name:TestClass.i field_type:Int32 loop:none l6 NullCheck [l1] dex_pc:1 env:[[i5,_,_,l1,i2]] loop:none l1 ParameterValue dex_pc:n/a loop:none Test: Manual; modify LSE to print the instruction above.
