This patch are for Crash-utility tool, it make crash tool support on loongarch64 architecture and the common commands(bt, p, rd, mod, log, set, dis, and so on). The upstream GDB code supports the loongarch64 architecture from version 13.1. See: https://sourceware.org/gdb/download/ANNOUNCEMENT But Crash-utility depends on gdb-10.2, gdb-10.2 do NOT supported loongarch64. So we need a patch(gdb-10.2-loongarch.patch) to support it. I don't have a better way to deal with this problem at the moment. I test this patch on Loongson 3C50000 processor platform. ...
