Nick Lewycky 40f8f2ff24 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

Rafael Espindola d2d0acdc04 142288 broke the build: 
Linking CXX executable ../../bin/llvm-as
../../lib/libLLVMAsmParser.a(LLParser.cpp.o):/home/espindola/llvm/llvm/lib/AsmParser/LLParser.cpp:function llvm::LLParser::ParseTargetDefinition(): error: undefined reference to 'llvm::TargetData::parseSpecifier(llvm::StringRef, llvm::TargetData*)'
clang-3: error: linker command failed with exit code 1 (use -v to see invocation)

Revert "Validate target data layout strings."

This reverts commit 599d2d4c25d3aee63a21d9c67a88cd43bd971b7e.

Bill Wendling aa9047d3f5 Now Igor, throw the switch...give my creation life! 
Use the custom inserter for the ARM setjmp intrinsics. Instead of creating the
SjLj dispatch table in IR, where it frequently violates serveral assumptions --
in particular assumptions made by the landingpad instruction about what can
branch to a landing pad and what cannot. Performing this in the back-end allows
us to violate these assumptions without the IR getting angry at us.

It also allows us to perform a small optimization. We can shove the address of
the dispatch's basic block into the function context and not have to add code
around the setjmp to check for the return value and jump to the dispatch.

Neat, huh?

Jim Grosbach 741cd73aab ARM NEON "vmov.i8" immediate assembly parsing and encoding. 
NEON immediates are "interesting". Start of the work to handle parsing them
in an 'as' compatible manner. Getting the matcher to play nicely with
these and the floating point immediates from VFP is an extra fun wrinkle.

Enrico Granata a9dbf4325e this patch introduces a new command script import command which takes as input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb

Eli Friedman a4c2602b71 Initial implementation of __atomic_is_lock_free. The input is the size of an atomic type rather than an atomic type itself just to save some implementation pain; I can change that if it seems worthwhile. 
I think this is the last hook needed for <atomic> besides defines for ATOMIC_CHAR_LOCK_FREE and friends.

Bill Wendling c68c8cb8d4 Add support for the Objective-C personality function to the instruction 
combining of the landingpad instruction. The ObjC personality function acts
almost identically to the C++ personality function. In particular, it uses
"null" as a "catch-all" value.

Tanya Lattner 49b3841398 The comparison of two vectors should return a signed result. hasIntegerRepresentation() used to always return false for vectors, but since it was changed, it also 
changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type.
I added a new test case and updated exisiting test cases that assumed an unsigned result.
