           Summary: MIPS should not use target_flags_explicit in insn
                    conditions
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jsm28@gcc.gnu.org
            Target: mips*-*-*


As explained in http://gcc.gnu.org/ml/gcc-patches/2010-10/msg00215.html MIPS
should not be using target_flags_explicit directly in macros such as
GENERATE_LL_SC and GENERATE_SYNC that are used in insn conditions; it should
only be used as part of initial option processing (no later than the option
override hook) to determine other state that then gets used in insn conditions
and elsewhere to control the code to generate.
