      "message": "Quick compiler: refactored listing \u0026 const fix\n\nThis CL started off as a simple fix to Issue 4959751, which\nidentified a case in which compiler debugging listings could read\nuninitialized data.  The fix ended up pulling a few strings - we\nhad two distinct dex printing routines (one was focused on SSA names\nand was used by the .dot graph dumper), while the other was used with\nverbose codegen listing.\n\nEnded up combining the two routines and significantly enhancing the\nvalue of the verbose debug output.  We now always use ssa register\nnames, and also show the constant values of ssa names which are known\nto be const following constant propagation.\n\nAlong the way, deleted a bit of useless code that remapped all\nregisters in a phi set to have the same name, and also got rid of\nsome duplicate listing helper LIR pseudo ops.\n\nSomee examples of the new listing:\n\n-------- dalvik offset: 0x2 @ const/4 v0_1#0x1, #1\n\nthe format of the vreg is:\n   v\u003corignal Dalvik vnum\u003e_\u003cssa instance\u003e[#hex value of immediate]\n\nIn this example, we don\u0027t add any new info (the listing already had #1),\nbut we also show this form in uses:\n\ninvoke-virtual v0_2, v1_3#0x40\n\nAlso improved is the listing output of potentially throwing instructions\nwhich are broken into two parts: the check portion and the work portion.\nBoth halves now show the full disassembly.  For example:\n\n-------- dalvik offset: 0x13 @ Check1: invoke-virtual v0_2, v1_3#0x40\n....code here\n....code here\n-------- dalvik offset: 0x13 @ Check2: invoke-virtual v0_2, v1_3#0x40\n\nDalvik instructions which are optimized away prior to code generation\nare displayed in sqare brackets.  For example:\n\n-------- dalvik offset: 0x16 @ [move-result-object v0_3]--optimized away\n\nFinally, Phi nodes show which incoming block an operand came through.\nIn the following example:\n\n-------- dalvik offset: 0x5 @ Phi v1_2 \u003d (v1_1#0x0:4, v1_2:12, v1_3#0x1:14)\n\nSreg v1_2 is a merge of a constant 0x0 from incoming block 4, a non-const\nvalue from block 12 and a const 0x1 from block 14.\n\nChange-Id: Ib6c19c19ab8a48509d43d8b0e5ed3e8e7ce9fc82\n"

To do this\nwe assign negative virtual register numbers and give them SSA names.\nAs part of this change, I did a general cleanup of the ssa naming.\nAn ssa name (or SReg) is in index into an array of (virtual reg, subscript)\npairs.  Previously, 16 bits were allocated for the reg and the subscript.\nThis CL expands the virtual reg and subscript to 32 bits each.\n\nMethod* is now treated as a RegLocation, and will be subject to\ntemp register tracking and reuse.  This CL does not yet include\nsupport for promotion of Method* - that will show up in the next one.\n\nAlso included is the beginning of a basic block optimization pass (not\nyet in a runable state, so conditionally compiled out).\n\n(cherry picked from commit f689ffec8827f1dd6b31084f8a6bb240338c7acf)\n\nChange-Id: Ibbdeb97fe05d0e33c1f4a9a6ccbdef1cac7646fc\n"
