* [yaml2obj] Add support for ELF e_flags.Daniel Sanders2014-03-31
| | | | | | | | | | | | | | | | Summary: The FileHeader mapping now accepts an optional Flags sequence that accepts the EF_<arch>_<flag> constants. When not given, Flags defaults to zero. Reviewers: atanasyan Reviewed By: atanasyan CC: llvm-commits Differential Revision: http://llvm-reviews.chandlerc.com/D3213 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205173 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: error when -compress-debug-sections is requested and zlib is not linkedDavid Blaikie2014-03-28
| | | | | | | | | | This is a bit of a stab in the dark, since I have zlib on my machine. Just going to bounce it off the bots & see if it sticks. Do we have some convention for negative REQUIRES: checks? Or do I just need to add a feature like I've done here? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205050 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Support for compressed debug info sectionsDavid Blaikie2014-03-27
| | | | | | | | | | | | | | | | | | | 1) When creating a .debug_* section and instead create a .zdebug_ section. 2) When creating a fragment in a .zdebug_* section, make it a compressed fragment. 3) When computing the size of a compressed section, compress the data and use the size of the compressed data. 4) Emit the compressed bytes. Also, check that only if a section has a compressed fragment, then that is the only fragment in the section. Assert-fail if the fragment's data is modified after it is compressed.

* Create .symtab_shndxr only when needed.Rafael Espindola2014-03-25
| | | | | | | | | | | | | | | | | | | | | | | We need .symtab_shndxr if and only if a symbol references a section with an index >= 0xff00. The old code was trying to figure out if the section was needed ahead of time, making it a fairly dependent on the code actually writing the table. It was also somewhat conservative and would create the section in cases where it was not needed. If I remember correctly, the old structure was there so that the sections were created in the same order gas creates them. That was valuable when MC's support for ELF was new and we tested with elf-dump.py. This patch refactors the symbol table creation to another class and makes it obvious that .symtab_shndxr is really only created when we are about to output a reference to a section index >= 0xff00. While here, also improve the tests to use macros. One file is one section short of needing .symtab_shndxr, the second one has just the right number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204769 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Support debug_loc under fissionDavid Blaikie2014-03-25
| | | | | | | | | | | | | | | | | | | | | | Implement debug_loc.dwo, as well as llvm-dwarfdump support for dumping this section. Outlined in the DWARF5 spec and http://gcc.gnu.org/wiki/DebugFission the debug_loc.dwo section has more variation than the standard debug_loc, allowing 3 different forms of entry (plus the end of list entry). GCC seems to, and Clang certainly, only use one form, so I've just implemented dumping support for that for now. It wasn't immediately obvious that there was a good refactoring to share the implementation of dumping support between debug_loc and debug_loc.dwo, so they're separate for now - ideas welcome or I may come back to it at some point. As per a comment in the code, we could choose different forms that may reduce the number of debug_addr entries we emit, but that will require further study. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204697 91177308-0d34-0410-b5e6-96231b3b80d8

* Object: Provide a richer means of describing auxiliary symbolsDavid Majnemer2014-03-19
| | | | | | | | | | | | | | | | The current state of affairs has auxiliary symbols described as a big bag of bytes. This is less than satisfying, it detracts from the YAML file as being human readable. Instead, allow for symbols to optionally contain their auxiliary data. This allows us to have a much higher level way of describing things like weak symbols, function definitions and section definitions. This depends on D3105.

* Object/COFF: change data type of SymbolNumber from int16 to uint16.Rui Ueyama2014-03-15
| | | | | | | | | | | | Microsoft PE/COFF Spec clearly states that the field is of signed interger type. However, in reality, it's unsigned. If cl.exe needs to create a large number of sections for COMDAT sections, it will just create more than 32768 sections. Handling large section number as negative number is not correct.

* Move duplicated code into a helper function (exposed through overload).Eli Bendersky2014-03-12
| | | | | | | | | | | | | | | | | | | There's a bit of duplicated "magic" code in opt.cpp and Clang's CodeGen that computes the inliner threshold from opt level and size opt level. This patch moves the code to a function that lives alongside the inliner itself, providing a convenient overload to the inliner creation. A separate patch can be committed to Clang to use this once it's committed to LLVM. Standalone tools that use the inlining pass can also avoid duplicating this code and fearing it will go out of sync. Note: this patch also restructures the conditinal logic of the computation to be cleaner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203669 91177308-0d34-0410-b5e6-96231b3b80d8
