* [llvm-cov] Add the project summary to each source file coverage report.Ying Yi2016-08-244-4/+60
| | | | | | | | | | | | This patch includes the following changes: - Included header "Code coverage report" and include the date that the report was created. - Included title (as specified in a command line option, (i.e llvm-cov -project-title="Simple Test") - In the summary, list the elf files that the source code file has contributed to. - Used column heading for "Line No.", "Count No.", Source".

| | | | | | | | | | | | | | | | | | Summary: The gold-plugin changes added along with the new LTO API in r278338 had the effect of removing the management of the PluginInputFile that ensured the files weren't released back to gold until the backend threads were complete. Add back the old file handling. Fixes PR29020. Reviewers: mehdi_amini Subscribers: mehdi_amini, llvm-commits, hjl.tools Differential Revision: https://reviews.llvm.org/D23721 llvm-svn: 279356

* llvm-objdump: add coff import library symbol listing supportSaleem Abdulrasool2016-08-182-0/+12
| | | | | | | | | | This adds behaviour similar to binutils' objdump which can show symbols in an import library. Differences from that stem around the fact that we do not create section symbols nor the all import import descriptor symbol reference. However, this does mean that the tool can serve as a possible replacement for the existing tool. llvm-svn: 279088
* llvm-readobj: handle import libraries with -coff-exportsSaleem Abdulrasool2016-08-182-0/+22

* [ThinLTO] Keep common symbols in ThinLTO modulesTeresa Johnson2016-08-182-0/+51
| | | | | | | | | | | | | | | | | | | | Summary: Skip the merging of common symbols for ThinLTO modules, they will be merged by the final native object link. Trying to merge the symbols and add to a combined module will incorrectly enable the common symbol to be internalized in the ThinLTO module. Additionally, we will not want to create a combined module for ThinLTO distributed builds. This fixes failures in 7 cpu2006 benchmarks from the new LTO API in ThinLTO mode.

* Restore "Resolution-based LTO API."Teresa Johnson2016-08-1118-97/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This restores commit r278330, with fixes for a few bot failures: - Fix a late change I had made to the save temps output file that I missed due to existing files sitting on my disk - Fix a bunch of Windows bot failures with "ambiguous call to overloaded function" due to confusion between llvm::make_unique vs std::make_unique (preface the new make_unique calls with "llvm::") - Attempt to fix a modules bot failure by adding a missing include to LTO/Config.h. Original change: Resolution-based LTO API. Summary: This introduces a resolution-based LTO API. The main advantage of this API over existing APIs is that it allows the linker to supply a resolution for each symbol in each object, rather than the combined object as a whole. This will become increasingly important for use cases such as ThinLTO which require us to process symbol resolutions in a more complicated way than just adjusting linkage.

This may be because AddressSanitizer is loaded too late (e.g. via dlopen) To fix this, %ld64 needs to load 'libclang_rt.asan_osx_dynamic.dylib' before libLTO.dylib, via DYLD_INSERT_LIBRARIES. This won't work by updating config.environment, since some shim binary in the way scrubs the env vars. Instead, provide the path to this lib through %asanrtlib, which can then be used by tests directly with DYLD_INSERT_LIBRARIES. rdar://problem/24300926 llvm-svn: 277778

* The next step along the way to getting good error messages for bad archives.Kevin Enderby2016-07-296-2/+79
| | | | | | | | | | | | | | | | | | | | | | | | As mentioned in commit log for r276686 this next step is adding a new method in the ArchiveMemberHeader class to get the full name that does proper error checking, and can be use for error messages. To do this the name of ArchiveMemberHeader::getName() is changed to ArchiveMemberHeader::getRawName() to be consistent with Archive::Child::getRawName(). Then the “new” method is the addition of a new implementation of ArchiveMemberHeader::getName() which gets the full name and provides proper error checking. Which is mostly a rewrite of what was Archive::Child::getName() and cleaning up incorrect uses of llvm_unreachable() in the code which were actually just cases of errors in the input Archives. Then Archive::Child::getName() is changed to return Expected<> and use the new implementation of ArchiveMemberHeader::getName() . Also needed to change Archive::getMemoryBufferRef() with these changes to return Expected<> as well to propagate Errors up. As well as changing Archive::isThinMember() to return Expected<> . llvm-svn: 277177

* Next step along the way to getting good error messages for bad archives.Kevin Enderby2016-07-253-3/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | I consulted with Lang Hames on this work, and the goal was to add a bit of "where" in the archive the error occurred along with what the error was. So this step changes ArchiveMemberHeader into a class with a pointer to the archive header and the parent archive. Which allows the methods in the ArchiveMemberHeader to determine which member the header is for to include that information in the error message. For this first step the "where" is just the offset to the member in the archive. The next step will be a new method on ArchiveMemberHeader to get the full name, if possible, to be use in the error message. Which will now be possible as ArchiveMemberHeader contains a pointer to the Archive with its string table and its size, etc. so the full name can be determined from the header if it is valid. Also this change adds the missing checks the archive header is actually contained in the buffer and is not truncated, as well as if the terminating characters are correct in the header. And changes one error message in Archive::Child::getNext() where the name or offset to member is now added. llvm-svn: 276686

* [ThinLTO/gold] Support for getting list of included objects from goldTeresa Johnson2016-07-222-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In the distributed backend case, the ThinLink step and the final native object link are separate processes. This can be problematic when archive libraries are involved in the link (e.g. via --start-lib/--end-lib pairs). The linker only includes objects from libraries when there is a strong reference to them, and depending on the intervening ThinLTO backend processes' importing/inlining, the strong references may appear different in the two link steps. See D22356 and D22467 for two scenarios where this causes issues. To ensure that the final link includes the same objects, this patch adds support for an "=filename" form of the thinlto-index-only plugin option, in which case objects gold included in the link are emitted to the given filename. This should be used as input to the final link (e.g. via the @filename option to gold), instead of listing all the objects within --start-lib/--end-lib pairs again. Note that the support for the gold callback that identifies included objects was added in gold version 1.12.
