2011-11-01Fix the representation of wide strings in the AST and IR so that it uses the ↵Eli Friedman
native representation of integers for the elements. This fixes a bunch of nastiness involving treating wide strings as a series of bytes. Patch by Seth Cantrell. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143417 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-30Add support for lazily linking bitcode files (using a newPeter Collingbourne
-mlink-bitcode-file flag), and more generally llvm::Modules, before running optimisations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143314 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-26Fix pr9614 by not emitting an available_externally function when it callsRafael Espindola
itself via an asm label. available_externally functions are supposed to correspond to an external function, and that is not the case in the examples in pr9614. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143049 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-17Initial implementation of __atomic_is_lock_free. The input is the size of ↵Eli Friedman
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142281 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-17The comparison of two vectors should return a signed result. ↵Tanya Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142250 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-13Recommit:Eric Christopher
Start handling debug line and scope information better: Migrate most of the location setting within the larger API in CGDebugInfo and update a lot of callers. Remove the existing file/scope change machinery in UpdateLineDirectiveRegion and replace it with DILexicalBlockFile usage.

2011-09-21ANSI C requires that a call to an unprototyped function type succeedJohn McCall
if the definition has a non-variadic prototype with compatible parameters. Therefore, the default rule for such calls must be to use a non-variadic convention. Achieve this by casting the callee to the function type with which it is required to be compatible, unless the target specifically opts out and insists that unprototyped calls should use the variadic rules. The only case of that I'm aware of is the x86-64 convention, which passes arguments the same way in both cases but also sets a small amount of extra information; here we seek to maintain compatibility with GCC, which does set this when calling an unprototyped function. Addresses PR10810 and PR10713. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140241 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19Throw the switch to convert clang to the new exception handling model!Bill Wendling
This model uses the 'landingpad' instruction, which is pinned to the top of the landing pad. (A landing pad is defined as the destination of the unwind branch of an invoke instruction.) All of the information needed to generate the correct exception handling metadata during code generation is encoded into the landingpad instruction. The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic call. It's lowered in much the same way as the intrinsic is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140049 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-16test/CodeGen/sse-builtins.c: Make this host-independent to unbreak ↵NAKAMURA Takumi
posix-unlike hosts. Without -ffreestanding, clang tries to seek /usr/include/stdlib.h in host filesystem, even on Windows hosts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139899 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15Tweak *mmintrin.h so that they don't make any bad assumptions about ↵Eli Friedman
alignment (which probably has little effect in practice, but better to get it right). Make the load in _mm_loadh_pi and _mm_loadl_pi a single LLVM IR instruction to make optimizing easier for CodeGen. rdar://10054986 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139874 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-07Switch clang over to using fence/atomicrmw/cmpxchg instead of the intrinsics ↵Eli Friedman
(which will go away). LLVM CodeGen does almost exactly the same thing with these and the old intrinsics, so I'm reasonably confident this will not break anything. There are still a few issues which need to be resolved with code generation for atomic load and store, so I'm not converting the places which need those for now. I'm not entirely sure what to do about __builtin_llvm_memory_barrier: the fence instruction doesn't expose all the possibilities which can be expressed by __builtin_llvm_memory_barrier. I would appreciate hearing from anyone who is using this intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139216 91177308-0d34-0410-b5e6-96231b3b80d8
