I've successfully bootstrapped this on loongarch64-linux-gnu and tried the added test cases. For loongarch64 the redundant extensions are removed for core_bench_list.c, core_init_matrix.c, core_list_init.c, matrix_add_const.c, and pr111384.c, but not mem-extend.c. Should I change something in LoongArch backend in order to make ext_dce work for mem-extend.c too? If yes then any pointers? -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
