* MC: mayAffectControlFlow() handling for variadic instructions.Jim Grosbach2013-07-22
| | | | | | | | | | | Variadic MC instructions don't note whether the variable operands are uses or defs, so mayAffectControlFlow() must conservatively assume they are defs and return true if the PC is in the operand list. rdar://14488628 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186846 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info Verifier: simplify DIxxx::VerifyManman Ren2013-07-20
| | | | | | | | | Simplify DIxxx:Verify to not call Verify on an operand. Instead, we use DebugInfoFinder to list all MDNodes that should be a DIScope and all MDNodes that should be a DIType and we will call Verify on those lists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186737 91177308-0d34-0410-b5e6-96231b3b80d8

* [Option] Add inclusion and exclusion flags to option parsingReid Kleckner2013-07-19
| | | | | | | | | | | | | | | | | | | Summary: This allows the clang driver to put MSVC compatible options in the same enumerator space as its normal options but exclude them from normal option parsing. Also changes the standard ParseArgs() method to consider unknown arguments with a leading slash as being inputs rather than flags.

* COFFDumper: Dump data directory entries.Rui Ueyama2013-07-18
| | | | | | | | | | | | | | | | | Summary: Dump optional data directory entries in the PE/COFF header, so that we can test the output of LLD linker. This patch updates the test binary file, but the source of the binary is the same. I just re-linked the file. I don't know how the previous file was linked, but the previous file did not have any data directory entries for some reason.

* [Support] Beef up and expose the response file parsing in llvm::clReid Kleckner2013-07-18
| | | | | | | | | | | | | | | | | | | The plan is to use it for clang and lld. Major behavior changes: - We can now parse UTF-16 files that have a byte order mark. - PR16209: Don't drop backslashes on the floor if they don't escape anything. The actual parsing loop was based on code from Clang's driver.cpp, although it's been rewritten to track its state with control flow rather than state variables.

* Fix a regression I introduced back in r178147.Rafael Espindola2013-07-18
| | | | | | | | | | | We don't want cast and dyn_cast to work on temporaries. They don't extend lifetime like a direct bind to a reference would, so they can introduce hard to find bugs.

* Change llvm-ar to use lib/Object.Rafael Espindola2013-07-12
| | | | | | | | | | | | | | | | | | | | | | This fixes two bugs is lib/Object that the use in llvm-ar found: * In OS X created archives, the name can be padded with nulls. Strip them. * In the constructor, remember the first non special member and use that in begin_children. This makes sure we skip all special members, not just the first one. The change to llvm-ar itself consist of * Using lib/Object for reading archives instead of ArchiveReader.cpp. * Writing the modified archive directly, instead of creating an in memory representation. The old Archive library was way more general than what is needed, as can be seen by the diffstat of this patch. Having llvm-ar using lib/Object now opens the way for creating regular symbol tables for both native objects and bitcode files so that we can use those archives for LTO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186197 91177308-0d34-0410-b5e6-96231b3b80d8
