Author: bernds Date: Wed Mar 17 09:25:35 2010 New Revision: 157511 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=157511 Log: PR rtl-optimization/42216 * regrename.c (create_new_chain): New function, broken out from... (scan_rtx_reg): ... here. Call it. Handle the case where we are appending a use to an empty chain. (build_def_use): Remove previous changes that convert OP_INOUT to OP_OUT operands; instead detect the case where an OP_INOUT operand uses a previously untracked register and create an empty chain for it.
