* [llvm-objcopy] Add -strip-non-alloc option to remove all non-allocated sectionsJake Ehrlich2017-11-141-0/+11
| | | | | | | | | This change adds a new flag not present in GNU objcopy that we call --strip-non-alloc. Differential Revision: https://reviews.llvm.org/D39926 llvm-svn: 318168
* [llvm-objcopy] Support the rest of the ELF formatsJake Ehrlich2017-11-141-6/+19
| | | | | | | | | | | | We haven't been supporting anything but ELF64LE since the start. Luckily this was always accounted for and the change is pretty trivial. B35281 requests this change for ELF32LE. This change adds support for ELF32LE, ELF64BE, and ELF32BE with all supported features that already existed for ELF64LE.

* [llvm-objcopy] Add --strip-debugJake Ehrlich2017-11-131-0/+8
| | | | | | | | | | | | | | | | Many projects use this option. There are two ways to use it. You can either a) Just use --strip-debug and keep the old file with debug content or b) you can use --strip-debug, --only-keep-debug, and --add-gnu-debuglink all in conjunction to create two separate files, the stripped file and the debug file. --only-keep-debug is more complicated than --strip-debug because it keeps the section headers without keeping section contents. That's not really supported by llvm-objcopy at the moment but I plan on adding it. So this change just supports a) and options to support b) will come soon.

* [llvm-objcopy] Add --strip-all option to llvm-objcopyJake Ehrlich2017-11-131-0/+20
| | | | | | | | | | | | | | This change adds a slightly less extreme form of stripping. It should remove any section that starts with ".debug" and should remove any symbol table or relocations. In general this strips out most of the stuff you don't need to execute but leaves a number of things around. This behavior has been designed to be compatible with GNU strip/objcopy --strip-all so that anywhere you currently use --strip-all you should be able to use llvm-objcopy as a drop in replacement.

* Revert "[ADT] Make Twine's copy constructor private."Zachary Turner2017-10-111-1/+1
| | | | | | | | | | This reverts commit 4e4ee1c507e2707bb3c208e1e1b6551c3015cbf5. This is failing due to some code that isn't built on MSVC so I didn't catch. Not immediately obvious how to fix this at first glance, so I'm reverting for now. llvm-svn: 315536
* [ADT] Make Twine's copy constructor private.Zachary Turner2017-10-111-1/+1
| | | | | | | | | | | | | | | | | There's a lot of misuse of Twine scattered around LLVM. This ranges in severity from benign (returning a Twine from a function by value that is just a string literal) to pretty sketchy (storing a Twine by value in a class). While there are some uses for copying Twines, most of the very compelling ones are confined to the Twine class implementation itself, and other uses are either dubious or easily worked around. This patch makes Twine's copy constructor private, and fixes up all callsites. Differential Revision: https://reviews.llvm.org/D38767 llvm-svn: 315530
* Reland "[llvm-objcopy] Add support for --strip-sections to remove all ↵Jake Ehrlich2017-10-111-3/+19
| | | | | | | | | | | | | | | | | | | | | section headers leaving only program headers and loadable segment data" ubsan caught an issue I made where I was converting a null pointer to a reference. elf utils implements a particularly extreme form of stripping that I'd like to support. eu-strip has an option called "strip-sections" that removes all section headers and leaves only program headers and the segment data. I have implemented this option partly as a test but mainly because in Fuchsia we would like to use this option to minimize the size of our executables. The other strip options that are on my list include --strip-all and --strip-debug. This is a preliminary implementation that I'd like to start using in Fuchsia builds if possible. This change implements such a stripping option for llvm-objcopy Differential Revision: https://reviews.llvm.org/D38335 llvm-svn: 315484

| | | | | | | | | | | This change adds support for removing sections using the -R field (as GNU objcopy does as well). This change should let us add many helpful tests and is a proper stepping stone for adding more general kinds of stripping. Differential Revision: https://reviews.llvm.org/D38260 llvm-svn: 315346

| | | | | | | | | | | | | | | | llvm-objcopy" This change adds the "-O binary" flag which directs llvm-objcopy to output the object file to the same format as GNU objcopy does when given the flag "-O binary".
