* MC: Separate creating a generic object writer from creating a target object ↵Peter Collingbourne2018-05-211-5/+3
| | | | | | | | | | | | | writer. NFCI. With this we gain a little flexibility in how the generic object writer is created. Part of PR37466. Differential Revision: https://reviews.llvm.org/D47045 llvm-svn: 332868
* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-011-1/+1
| | | | | | | | | | | | | | | | We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* [WebAssembly] Write DWARF data into wasm object fileSam Clegg2018-04-261-1/+28
| | | | | | | | | | | - Writes ".debug_XXX" into corresponding custom sections. - Writes relocation records into "reloc.debug_XXX" sections. Patch by Yury Delendik! Differential Revision: https://reviews.llvm.org/D44184 llvm-svn: 330982
* [WebAssembly] Update MCObjectWriter and associated interfaces after r315327Derek Schuff2017-10-101-2/+4

* [MC] Plumb unique_ptr<MCWasmObjectTargetWriter> through createWasmObjectWriterLang Hames2017-10-101-2/+2
| | | | | | | | | | to WasmObjectWriter's constructor. Fixes the same ownership issue for COFF that r315245 did for MachO: WasmObjectWriter takes ownership of its MCWasmObjectTargetWriter, so we want to pass this through to the constructor via a unique_ptr, rather than a raw ptr. llvm-svn: 315260
* [WebAssembly] Update relocation names to match specSam Clegg2017-09-011-3/+3

* [WebAssembly] Use __stack_pointer global when writing wasm binarySam Clegg2017-06-161-0/+2
| | | | | | | | | | | | | | | | | | This ensures that symbolic relocations are generated for stack pointer manipulations. These relocations are of type R_WEBASSEMBLY_GLOBAL_INDEX_LEB. This change also adds support for reading relocations of this type in WasmObjectFile.cpp. Since its a globally imported symbol this does mean that the get_global/set_global instruction won't be valid until the objects are linked that global used in no longer an imported global.

* Move Object format code to lib/BinaryFormat.Zachary Turner2017-06-071-1/+1
| | | | | | | | | | | | This creates a new library called BinaryFormat that has all of the headers from llvm/Support containing structure and layout definitions for various types of binary formats like dwarf, coff, elf, etc as well as the code for identifying a file from its magic. Differential Revision: https://reviews.llvm.org/D33843 llvm-svn: 304864
* [WebAssembly] MC: Refactor relocation handlingSam Clegg2017-06-061-0/+7
| | | | | | | | | | | | | The change cleans up and unifies the handling of relocation entries in WasmObjectWriter. Type index relocation no longer need to be handled separately. The only externally visible change should be that type index relocations are no longer grouped at the end. Differential Revision: https://reviews.llvm.org/D33918 llvm-svn: 304816
* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
* [WebAssembly] Basic support for Wasm object file encoding.Dan Gohman2017-02-241-2/+46
| | | | | | | | | With the "wasm32-unknown-unknown-wasm" triple, this allows writing out simple wasm object files, and is another step in a larger series toward migrating from ELF to general wasm object support. Note that this code and the binary format itself is still experimental. llvm-svn: 296190
* [WebAssembly] Add skeleton MC support for the Wasm container formatDan Gohman2017-02-221-0/+48
This just adds the basic skeleton for supporting a new object file format. All of the actual encoding will be implemented in followup patches. Differential Revision: https://reviews.llvm.org/D26722 llvm-svn: 295803
