Subject[PATCH] perf symbol: Add LoongArch case in get_plt_sizes()
Date
We can see the following definitions in bfd/elfnn-loongarch.c:

#define PLT_HEADER_INSNS 8
#define PLT_HEADER_SIZE (PLT_HEADER_INSNS * 4)

#define PLT_ENTRY_INSNS 4
#define PLT_ENTRY_SIZE (PLT_ENTRY_INSNS * 4)

so plt header size is 32 and plt entry size is 16 on LoongArch,
let us add LoongArch case in get_plt_sizes().
