Some compilers such as mwccarm can generate multiple .data sections in the same object file, but clicking a data symbol in objdiff shows a hex view for only the first .data section. Meanwhile, the target object has only one .data section, so the hex view is diffing all of the target data with only a single chunk of base object data.

My proposed solution is to "combine" sections with equal names, ordered from lowest to highest section index. There's a checkbox under "Diff Options" to enable this when needed.

Yeah, this is tricky. Would probably require keeping track of every symbol and their adjusted address. Luckily this only affects the relocation display on hover, so this can be revisited later.
