| | | | | | | This reverts commit r229123. It was a red herring, the bug was present without r229082. llvm-svn: 229205
* CodeGen: Correctly convert atomic bool from i8 to i1David Majnemer2015-02-141-1/+1
| | | | | | | | | Bools are a little tricky, they are i8 in memory and must be coerced back to i1 before further operations can be performed on them. This fixes PR22577. llvm-svn: 229204

| | | | | | | | | | | | declarations and just use the legacy namespace qualifier in this file and the permanent header name. The old wrapper header is going away to make LLVM's build more modular, and without updating Clang I can't easily start to add usage of the new pass manager to Clang. This should make it more clear in the code which set of types is doing what. llvm-svn: 229090
* MS ABI: Implement /volatile:msDavid Majnemer2015-02-138-13/+96
| | | | | | | | | | | | The /volatile:ms semantics turn volatile loads and stores into atomic acquire and release operations. This distinction is important because volatile memory operations do not form a happens-before relationship with non-atomic memory. This means that a volatile store is not sufficient for implementing a mutex unlock routine. Differential Revision: http://reviews.llvm.org/D7580 llvm-svn: 229082

| | | | | | | | | | entity, put the originally-canonical decl IDs in the right places in the redecl chain rather than reordering them all to the start. If we don't ensure that the redecl chain order is consistent with the topological module order, we can fail to make a declaration visible if later declarations are in more IDNSs than earlier ones (for instance, because the earlier decls are invisible friends). llvm-svn: 228978

* Mangle the IsSystem bit into the .pcm file nameBen Langmuir2015-02-124-3/+17
| | | | | | | | | When mangling the module map path into a .pcm file name, also mangle the IsSystem bit, which can also depend on the header search paths. For example, the user may change from -I to -isystem. This can affect diagnostics in the importing TU. llvm-svn: 228966

| | | | | | | | Partially revert r223927 because LLVM gained support for 128-bit integers in r227089. Modify and keep the tests that verify the definition of the macro __SIZEOF_INT128__ for MIPS64 BE & LE in the preprocessor. llvm-svn: 228918
* Add InlineAsmDiagnosticHandler for bitcode inputSteven Wu2015-02-121-0/+8
| | | | | | | | | | | | | | | | | | | | Summary: This patch installs an InlineAsmDiagnosticsHandler to avoid the crash report when the input is bitcode and the bitcode contains invalid inline assembly. The handler will simply print the same error message that will print from the backend.

| | | | | | | | (or of a lambda init-capture, which is sort-of such a variable). The semantics of such constructs will change when we implement N3922, so we intend to warn on this in Clang 3.6 then change the semantics in Clang 3.7. llvm-svn: 228792

* Do not force "-static" for aarch64 iOS kernel/kext assembly code.Bob Wilson2015-02-101-2/+1
| | | | | | | | | | | Somehow a check for aarch64 was added to the Darwin toolchain's isKernelStatic function as part of the initial commit for Apple's arm64 target (r205100). That check was not in any of Apple's internal code and no one here knows where it came from. It has been harmless because "-static" does not change much, if anything, for arm64 iOS code, but it makes no sense to keep this check. llvm-svn: 228673

* Be more conservative about gethostname()'s truncating behaviourBen Langmuir2015-02-091-1/+5
| | | | | | | | Don't assume it will provide an error or null-terminate the string on truncation, since POSIX doesn't guarantee either behaviour (although Linux and Darwin at least will do the 'right thing'). llvm-svn: 228613
* Diagnose timeouts in the LockFileManager and delete the dead lock fileBen Langmuir2015-02-091-2/+12
| | | | | | | | | | | | If the lock file manager times out, we should give an error rather than silently trying to load the existing module. And delete the (presumably) dead lock file, since it will otherwise prevent progress in future invokations. This is unsound since we have no way to prove that the lock file we are deleting is the same one we timed out on, but since the lock is only to avoid excessive rebuilding anyway it should be okay. Depends on llvm r228603. llvm-svn: 228604

| | | | | | | | | If gethostname() is not successful, just skip adding the hostname to the module hash. And don't bother setting hostname[255] = 0, since if gethostname() is successful, it will be null-terminated already (and if it's not successful we don't read the string now. llvm-svn: 228601
