...nary, we have to switch from each other. we can tell if a function is thumb or arm code by looking at the symbol table entry, when in thumb code, the lowest bit of the symbol value will be set to '1'. so how these logic can be implemented while still adapt to the structure of the code?

The code is only valid for executable files, not relocatable files. st_shndx should be used to determine if the symbol is in the given section. Also st_value can hold the offset into st_shndx, not the actual address. Also it doesn't handle non-function symbols. For the se...
