  "message": "i386: Merge duplicate preferred_for_speed attributes on QImode NDD patterns\n\nSeveral QImode integer patterns has two separate attr \"preferred_for_speed\"\nset, one gating the NDD memory-form alternatives with\nTARGET_ENABLE_NDD_MEM, and the existing one is for !TARGET_PARTIAL_REG_STALL.\nThe later one will make genattrtab regenerates the cond based on\n!PARTIAL_REG_STALL only and overrides the TARGET_ENABLE_NDD_MEM, so the NDD\nmemory alternatives were always preferred for speed regardless of the\nX86_TUNE_ENABLE_NDD_MEM enabled or disabled.\n\nCombine both conditions into a single preferred_for_speed cond per\npattern. For *ashlqi3_1 alternative 5 belongs to both sets, so it is\ngated on TARGET_ENABLE_NDD_MEM \u0026\u0026 !TARGET_PARTIAL_REG_STALL.\n\ngcc/ChangeLog:\n\n\t* config/i386/i386.md (*addqi_1\u003cnf_name\u003e): Merge the two\n\tpreferred_for_speed attributes into one.\n\t(*andqi_1\u003cnf_name\u003e): Likewise.\n\t(*andqi_2_maybe_si): Likewise.\n\t(*\u003ccode\u003eqi_1\u003cnf_name\u003e): Likewise.\n\t(*notxorqi_1): Likewise.\n\t(*one_cmplqi2_1): Likewise.\n\t(*ashlqi3_1\u003cnf_name\u003e): Likewise.\n\ngcc/testsuite/ChangeLog:\n\n\t* gcc.target/i386/apx-ndd-mem-tune.c: New test.\n",
