  "message": "RISC-V: Fix multiple bugs in riscv_macro_fusion_pair_p\n\nFix several correctness and minor issues in the fusion pair\nmatching logic:\n\nXINT (prev_set, 1) in RISCV_FUSE_AUIPC_LD incorrectly accesses\nthe SET node rather than its UNSPEC source operand.  Use\nXINT (SET_SRC (prev_set), 1) to match riscv_fuse_auipc_addi.\n\nRISCV_FUSE_CACHE_ALIGNED_STD compared base registers with !\u003d instead\nof \u003d\u003d, causing it to match stores with different bases rather than\nthe same base which is required for cache-line alignment analysis.\n\nRISCV_FUSE_B_ALUI sub+smax pattern had a redundant CONST_INT_P\ncheck on the same operand already validated by the CONST0_RTX\ncomparison.\n\nRISCV_FUSE_LDINDEXED had a duplicate REG_P check on the same\noperand.\n\nAlso fix a typo (\"hte\" -\u003e \"the\") in a comment and correct the\ndump output string from \"RISCV_FUSE_ALIGNED_STD\" to\n\"RISCV_FUSE_CACHE_ALIGNED_STD\" for the cache-aligned case.\n\nTests are marked XFAIL as no upstream mtune currently enables\nAUIPC_LD, CACHE_ALIGNED_STD, B_ALUI, or LDINDEXED.  The\nexisting fusion-auipc-addi.c test indirectly validates the\nXINT fix since AUIPC_ADDI shares the same UNSPEC_AUIPC check\ncode path.\n\ngcc/ChangeLog:\n\n\t* config/riscv/riscv-fusion.cc (riscv_macro_fusion_pair_p):\n\tFix XINT to access SET_SRC (prev_set) in AUIPC_LD case.\n\tFix base register comparison from !\u003d to \u003d\u003d in\n\tCACHE_ALIGNED_STD case.  Remove redundant CONST_INT_P\n\tcheck in B_ALUI sub+smax case.  Remove duplicate REG_P\n\tcheck in LDINDEXED case.  Fix typo in comment.  Fix dump\n\toutput name for CACHE_ALIGNED_STD.\n\ngcc/testsuite/ChangeLog:\n\n\t* gcc.target/riscv/fusion-auipc-ld.c: New test.\n\t* gcc.target/riscv/fusion-b-alui.c: New test.\n\t* gcc.target/riscv/fusion-cache-aligned-std.c: New test.\n\t* gcc.target/riscv/fusion-ldindexed.c: New test.\n",
