gdb/gdbserver: LoongArch: Improve implementation of fcc registers The current implementation of the fcc register is referenced to the user_fp_state structure of the kernel uapi [1]. struct user_fp_state { uint64_t fpr[32]; uint64_t fcc; uint32_t fcsr; }; But it is mistakenly defined as a 64-bit fputype register, resulting in a confusing output of "info register". (gdb) info register ... fcc {f = 0x0, d = 0x0} {f = 0, d = 0} ... According to "Condition Flag Register" in "LoongArch Reference Manual" [2], there are 8 condition flag registers of size 1. Use 8 registers of uint8 to make it easier for users to view the fcc register groups. (gdb) info register ... fcc0 0x1 1 fcc1 0x0 0 fcc2 0x0 0 fcc3 0x0 0 fcc4 0x0 0 fcc5 0x0 0 fcc6 0x0 0 fcc7 0x0 0 ...
