[llvm-objcopy] Add -F|--target compatibility Summary: This change adds support for the GNU --target flag, which sets both --input-target and --output-target. GNU objcopy doesn't do any checking for whether both --target and --{input,output}-target are used, and so it allows both, e.g. "--target A --output-target B" is equivalent to "--input-target A --output-target B" since the later command line flag would override earlier ones. This may be error prone, so I chose to implement it as an error if both are used. I'm not sure if anyone is actually using both.

[llvm-objcopy] Dwarf .debug section compression support (zlib, zlib-gnu). Third Attempt: - Alignment issues resolved. - zlib::isAvailable() detected. - ArrayRef misuse fixed. Usage: llvm-objcopy --compress-debug-sections=zlib foo.o llvm-objcopy --compress-debug-sections=zlib-gnu foo.o In both cases the debug section contents is compressed with zlib. In the GNU style case the header is the "ZLIB" magic string followed by the uint64 big- endian decompressed size. In the non-GNU mode the header is the Elf(32|64)_Chdr. Decompression support is coming soon. Differential Revision: https://reviews.llvm.org/D49678 llvm-svn: 341635

[llvm-objcopy] Add --only-keep-debug as a noop This option just keeps being a problem and really needs to be implemented in some fashion. Implementing it properly requires some kind of "replaceSectionReference" method because all the existing links need to be maintained. The desired behavior is just for allocated sections to become NOBITS but actually implementing that is rather tricky due to the current design of llvm-objcopy. However converting allocated sections to NOBITS is just an optimization and not something debuggers need. Debuggers can debug a stripped executable and take an unstripped executable for that stripped executable as input. Additionally allocated sections account for a very small part of debug binaries so this optimization is quite small. I propose that for the time being we implement this as a NOP so that people can use llvm-objcopy where they need to, just in a sub-optimal way. This option has already blocked a lot of people and its currently blocking me. llvm-svn: 332396
