我照你们的文档 编译安装完 gcc 9.1.0 然后去编译mysql5.7.27的时候编译到80多后报错 是要怎么处理 之前用gcc7.3.0是可以编译过的 我现在是想-mtune=tsv110 加这个编译参数看效果/root/mysql-5.7.27/storage/innobase/buf/buf0buf.cc: In function ‘ulint buf_page_optimistic_get(ulint, buf_block_t*, ib_uint64_t, const char*, ulint, mtr_t*)’:/root/mysql-5.7.27/storage/innobase/buf/buf0buf.cc:4784:1: error: unrecognizable insn: 4784 | } | ^(insn 530 529 531 36 (set (reg:CC 66 cc) (compare:CC (reg:DI 278) (const_int 536870912 [0x20000000]))) "/root/mysql-5.7.27/storage/innobase/include/sync0rw.ic":453:12 -1 (nil))during RTL pass: vregs
