Author: ebotcazou Date: Sun Jan 21 22:32:39 2007 New Revision: 121037 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=121037 Log: PR rtl-optimization/29329 * combine.c (replaced_rhs_insn): Rename to i2mod. (replaced_rhs_value): Rename to i2mod_new_rhs. (i2mod_old_rhs): New global variable. (combine_instructions): Adjust for above change. Save a copy of the old RHS into i2mod_old_rhs when the contents of a REG_EQUAL note are substituted in the second instruction. (distribute_notes) <REG_DEAD>: Adjust for above change. Do not ditch the note if it pertains to the second eliminated register and this register is mentioned in i2mod_old_rhs. Revert: 2006-09-12 Eric Botcazou <[EMAIL PROTECTED]> * combine.c (distribute_notes) <REG_DEAD>: Do not consider SETs past the insn to which the note was originally attached.
