* Revert "[llvm-objcopy] Add support for .dynamic, .dynsym, and .dynstr"Jake Ehrlich2017-09-191-34/+0
| | | | | | | This reverts commit r313663. Broken because overlapping-sections was reverted. llvm-svn: 313665
* Revert "[llvm-objcopy] Add support for nested and overlapping segments"Jake Ehrlich2017-09-191-1/+0
| | | | | | This reverts commit r313656. Appears to be broken on Windows. llvm-svn: 313664
* [llvm-objcopy] Add support for .dynamic, .dynsym, and .dynstrJake Ehrlich2017-09-191-0/+34
| | | | | | | | | | | | | | | This change adds support for sections involved in dynamic loading such as SHT_DYNAMIC, SHT_DYNSYM, and allocated string tables. The two added binaries used for tests can be downloaded [[ https://drive.google.com/file/d/0B3gtIAmiMwZXOXE3T0RobFg4ZTg/view?usp=sharing | here ]] and [[ https://drive.google.com/file/d/0B3gtIAmiMwZXTFJSQUJZMGxNSXc/view?usp=sharing | here ]] Differential Revision: https://reviews.llvm.org/D36560 llvm-svn: 313663
* [llvm-objcopy] Add support for nested and overlapping segmentsJake Ehrlich2017-09-191-0/+1
| | | | | | | | | This change adds support for nested and even overlapping segments. This means that PT_PHDR, PT_GNU_RELRO, PT_TLS, and PT_DYNAMIC can be supported properly. Differential Revision: https://reviews.llvm.org/D36558 llvm-svn: 313656
* [llvm-objcopy] Add support for special section indexes in symbol table ↵Petr Hosek2017-09-071-1/+19
| | | | | | | | | | | | | | | greater than SHN_LORESERVE As is indexes above SHN_LORESERVE will not be handled correctly because they'll be treated as indexes of sections rather than special values that should just be copied. This change adds support to copy them though. Patch by Jake Ehrlich Differential Revision: https://reviews.llvm.org/D37393 llvm-svn: 312756
* Reland "[llvm-objcopy] Add support for relocations"Petr Hosek2017-09-061-0/+29

* [llvm-objcopy] New layout algorithm that lays out segments firstPetr Hosek2017-08-261-0/+2
| | | | | | | | | | | | | | | | The current file layout algorithm in llvm-objcopy is simple but difficult to reason about. It also makes it very complicated to support nested segments and to support segments that have offsets that come before a point after the program headers. To support these cases and simplify one of the most critical parts llvm-objcopy I rewrote the layout algorithm. Laying out segments first solves most of the issues encountered by the previous algorithm. Patch by Jake Ehrlich Differential Revision: https://reviews.llvm.org/D36494 llvm-svn: 311825
* Reland "[llvm][llvm-objcopy] Added support for outputting to binary in ↵Petr Hosek2017-08-041-9/+46
| | | | | | | | | | | | | | | | 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". This was done by splitting the Object class into two subclasses ObjectELF and ObjectBianry which each output a different format but relay on the same code to read in the Object in Object.

| | | | | | | | | | | | | | | As discussed on llvm-dev I've implemented the first basic steps towards llvm-objcopy/llvm-objtool (name pending).
