* Link with -rdynamic instead of -Wl,-export-dynamic.Bob Wilson2013-08-022-2/+2
| | | | | | | | | | | | | | | Recent versions of the OS X linker support this but follow the existing OS X linker convention of using an underscore in the option name, i.e., -export_dynamic. Rather than changing our configure scripts to check for that alternate spelling, it is simpler to just use the compiler's -rdynamic option and let it deal with translating that to the appropriate linker option. One potential disadvantage of this approach is that the compiler will typically ignore -rdynamic on platforms where it is not supported, so the HAVE_LINK_EXPORT_DYNAMIC in config.h will not necessarily show whether that option has any effect or not. I don't see any in-tree uses of that macro, so I'm assuming it is OK. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187686 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info Finder|Verifier: handle DbgLoc attached to instructions.Manman Ren2013-08-011-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Also remove checking of llvm.dbg.sp since it is not used in generating dwarf. Current state of Finder: DebugInfoFinder tries to list all debug info MDNodes used in a module. To list debug info MDNodes used by an instruction, DebugInfoFinder provides processDeclare, processValue and processLocation to handle DbgDeclareInst, DbgValueInst and DbgLoc attached to instructions. processModule will go through all DICompileUnits in llvm.dbg.cu and list debug info MDNodes used by the CUs. TODO: 1> Finder has a list of CUs, SPs, Types, Scopes and global variables. We need to add a list of variables that are used by DbgDeclareInst and DbgValueInst. 2> MDString fields should be null or isa<MDString> and MDNode fields should be null or isa<MDNode>. We currently use empty string or int 0 to represent null. 3> Go though Verify functions and make sure that they check field types. 4> Clean up existing testing cases to remove llvm.dbg.sp and make sure each testing case has a llvm.dbg.cu. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187609 91177308-0d34-0410-b5e6-96231b3b80d8

* Option parsing: add support for alias arguments.Hans Wennborg2013-07-313-0/+13
| | | | | | | | | | | | | | | | | | This makes option aliases more powerful by enabling them to pass along arguments to the option they're aliasing. For example, if we have a joined option "-foo=", we can now specify a flag option "-bar" to be an alias of that, with the argument "baz". This is especially useful for the cl.exe compatible clang driver, where many options are aliases. For example, this patch enables us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to "-Werror" (again, -W is a joined option).

| | | | | | | | | | | When registers must be live throughout the scheduling region, increase the limit for the register class.

* Add support for the 's' operation to llvm-ar.Rafael Espindola2013-07-291-0/+2
| | | | | | | | | | | | If no other operation is specified, 's' becomes an operation instead of an modifier. The s operation just creates a symbol table. It is the same as running ranlib. We assume the archive was created by a sane ar (like llvm-ar or gnu ar) and if the symbol table is present, then it is current. We use that to optimize the most common case: a broken build system that thinks it has to run ranlib. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187353 91177308-0d34-0410-b5e6-96231b3b80d8

* Make .bc en/decoding of AttrKind stableTobias Grosser2013-07-261-0/+41
| | | | | | | | | | | | | | | | The bitcode representation attribute kinds are encoded into / decoded from should be independent of the current set of LLVM attributes and their position in the AttrKind enum. This patch explicitly encodes attributes to fixed bitcode values. With this patch applied, LLVM does not silently misread attributes written by LLVM 3.3. We also enhance the decoding slightly such that an error message is printed if an unknown AttrKind encoding was dected. Bonus: Dropping bitcode attributes from AttrKind is now easy, as old AttrKinds do not need to be kept to support the Bitcode reader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187186 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-262-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The LLVM portions of this patch simply add ppc64le coverage everywhere that ppc64 coverage currently exists. There is nothing of any import worth testing until such time as little-endian code generation is implemented. In the corresponding Clang patch, there is a new test case variant to ensure that correct built-in defines for little-endian code are generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187179 91177308-0d34-0410-b5e6-96231b3b80d8
