Hello! 2016-05-02 Uros Bizjak <ubizjak@gmail.com> * config/i386/predicates.md (nonimm_ssenomem_operand): New predicate. (register_mixssei387nonimm_operand): Remove predicate. * config/i386/i386.md (*fop_<mode>_comm): Merge from *fop_<mode>_comm_mixed and *fop_<mode>_comm_i387. Disable unsupported alternatives using "enabled" attribute. Also check X87_ENABLE_ARITH for TARGET_MIX_SSE_I387 alternatives. (*fop_<mode>_1): Merge from *fop_<mode>_1_mixed and *fop_<mode>_1_i387. Disable unsupported alternatives using "enabled" attribute. Use nonimm_ssenomem_operand as operand 1 predicate. Also check X87_ENABLE_ARITH for TARGET_MIX_SSE_I387 alternatives. * config/i386/predicates.md (nonimm_ssenomem_operand): New predicate. (register_mixssei387nonimm_operand): Remove predicate. Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}. Committed to mainline SVN. Uros.
