[PATCH] D39713: [llvm-objcopy] Change -O binary to respect section removal and behave like GNU objcopy

[Jake Ehrlich via Phabricator via llvm-commits]

jakehehrlich created this revision.

The original -O binary implementation just copied segment data from the object and dumped it into a file. This doesn't take into account any operations performed on objects such as section removal.  GNU objcopy has some specific behavior that we'd also like to respect. For instance using -O binary and -j <some_section> will dump <some_section> to a file. This change implements GNU objcopy style -O binary to as close of an approximation as I can determine.
