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"

      "message": "Use slow-path static field accessors; added tests\n\nModified the compiler to always take the slow path for static\nfield accesses.  Still need to implement the fast path, but this\nallows us to test the slow path now.\n\nIt\u0027s also about time we added command-line (or other) options for\ncompiler control.  We\u0027ll want to have a testing option to force slow\npaths for testing, and also an option to control the compiler\u0027s\ndebug output (which is starting to get annoying).\n\nChange-Id: I9c1bc6faea0042894270d242366c688f1662842b\n"
