* Replace push_back(Constructor(foo)) with emplace_back(foo) for non-trivial typesBenjamin Kramer2015-05-291-10/+10
| | | | | | | | | | | | | | | | | | | | If the type isn't trivially moveable emplace can skip a potentially expensive move. It also saves a couple of characters. Call sites were found with the ASTMatcher + some semi-automated cleanup. memberCallExpr( argumentCountIs(1), callee(methodDecl(hasName("push_back"))), on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))), hasArgument(0, bindTemporaryExpr( hasType(recordDecl(hasNonTrivialDestructor())), has(constructExpr()))), unless(isInTemplateInstantiation())) No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@238601 91177308-0d34-0410-b5e6-96231b3b80d8

* [modules] Add local submodule visibility support for declarations.Richard Smith2015-05-151-0/+6
| | | | | | | | | | | | | With this change, enabling -fmodules-local-submodule-visibility results in name visibility rules being applied to submodules of the current module in addition to imported modules (that is, names no longer "leak" between submodules of the same top-level module). This also makes it much safer to textually include a non-modular library into a module: each submodule that textually includes that library will get its own "copy" of that library, and so the library becomes visible no matter which including submodule you import. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@237473 91177308-0d34-0410-b5e6-96231b3b80d8
* Add flag to enable native half typePirama Arumuga Nainar2015-05-141-1/+1
| | | | | | | | | | | | | | | | | | | Summary: r235215 enables support in LLVM for legalizing f16 type in the IR. AArch64 already had support for this. r235215 and some backend patches brought support for ARM, X86, X86-64, Mips and Mips64. This change exposes the LangOption 'NativeHalfType' in the command line, so the backend legalization can be used if desired. NativeHalfType is enabled for OpenCL (current behavior) or if '-fnative-half-type' is set.

* Make GNUInline consistent with whether we use traditional GNU inline semantics.Peter Collingbourne2015-05-131-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we were setting LangOptions::GNUInline (which controls whether we use traditional GNU inline semantics) if the language did not have the C99 feature flag set. The trouble with this is that C++ family languages also do not have that flag set, so we ended up setting this flag in C++ modes (and working around it in a few places downstream by also checking CPlusPlus). The fix is to check whether the C89 flag is set for the target language, rather than whether the C99 flag is cleared. This also lets us remove most CPlusPlus checks. We continue to test CPlusPlus when deciding whether to pre-define the __GNUC_GNU_INLINE__ macro for consistency with GCC. There is a change in semantics in two other places where we weren't checking both CPlusPlus and GNUInline (FunctionDecl::doesDeclarationForceExternallyVisibleDefinition and FunctionDecl::isInlineDefinitionExternallyVisible), but this change seems to put us back into line with GCC's semantics (test case: test/CodeGen/inline.c). While at it, forbid -fgnu89-inline in C++ modes, as GCC doesn't support it, it didn't have any effect before, and supporting it just makes things more complicated.

* [modules] Add -fmodules-local-submodule-visibility flag.Richard Smith2015-05-011-0/+2
| | | | | | | | | | | | | | | | This flag specifies that the normal visibility rules should be used even for local submodules (submodules of the currently-being-built module). Thus names will only be visible if a header / module that declares them has actually been included / imported, and not merely because a submodule that happened to be built earlier declared those names. This also removes the need to modularize bottom-up: textually-included headers will be included into every submodule that includes them, since their include guards will not leak between modules. So far, this only governs visibility of macros, not of declarations, so is not ready for real use yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@236350 91177308-0d34-0410-b5e6-96231b3b80d8

* Support generating NMake/Jom-style depfiles.Paul Robinson2015-04-271-0/+2
| | | | | | | | | | | | | | | | NMake is a Make-like builder that comes with Microsoft Visual Studio. Jom (https://wiki.qt.io/Jom) is an NMake-compatible build tool. Dependency files for NMake/Jom need to use double-quotes to wrap filespecs containing special characters, instead of the backslash escapes that GNU Make wants.

* Create a frontend flag to disable CUDA cross-target call checksEli Bendersky2015-04-151-0/+3
| | | | | | | | | | | | | | | | | For CUDA source, Sema checks that the targets of call expressions make sense (e.g. a host function can't call a device function). Adding a flag that lets us skip this check. Motivation: for source-to-source translation tools that have to accept code that's not strictly kosher CUDA but is still accepted by nvcc. The source-to-source translation tool can then fix the code and leave calls that are semantically valid for the actual compilation stage.

* uselistorder: -mllvm -preserve-bc-use-list-order => -emit-llvm-uselistsDuncan P. N. Exon Smith2015-04-151-0/+4
| | | | | | | | | | | | | | | Stop relying on `cl::opt` to pass along the driver's decision to preserve use-lists. Create a new `-cc1` option called `-emit-llvm-uselists` that does the right thing (when -emit-llvm-bc). Note that despite its generic name, it *doesn't* do the right thing when -emit-llvm (LLVM assembly) yet. I'll hook that up soon. This doesn't really change the behaviour of the driver. The default is still to preserve use-lists for `clang -emit-llvm` and `clang -save-temps`, and nothing else. But it stops relying on global state (and also is a nicer interface for hackers using `clang -cc1`). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@234962 91177308-0d34-0410-b5e6-96231b3b80d8

* Process the -freciprocal-math optimization flag (PR20912)Sanjay Patel2015-04-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | The driver currently accepts but ignores the -freciprocal-math flag. This patch passes the flag through and enables 'arcp' fast-math-flag generation in IR. Note that this change does not actually enable the optimization for any target. The reassociation optimization that this flag specifies was implemented by http://reviews.llvm.org/D6334 : http://llvm.org/viewvc/llvm-project?view=revision&revision=222510 Because the optimization is done in the backend rather than IR, the backend must be modified to understand instruction-level fast-math-flags or a new function-level attribute must be created. Also note that -freciprocal-math is independent of any target-specific usage of reciprocal estimate hardware instructions. That requires its own flag ('-mrecip'). https://llvm.org/bugs/show_bug.cgi?id=20912 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@234493 91177308-0d34-0410-b5e6-96231b3b80d8

* C++14: Disable sized deallocation by default due to ABI breakageReid Kleckner2015-03-201-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no widely deployed standard libraries providing sized deallocation functions, so we have to punt and ask the user if they want us to use sized deallocation. In the future, when such libraries are deployed, we can teach the driver to detect them and enable this feature. N3536 claimed that a weak thunk from sized to unsized deallocation could be emitted to avoid breaking backwards compatibility with standard libraries not providing sized deallocation. However, this approach and other variations don't work in practice. With the weak function approach, the thunk has to have default visibility in order to ensure that it is overridden by other DSOs providing sized deallocation. Weak, default visibility symbols are particularly expensive on MachO, so John McCall was considering disabling this feature by default on Darwin. It also changes behavior ELF linking behavior, causing certain otherwise unreferenced object files from an archive to be pulled into the link. Our second approach was to use an extern_weak function declaration and do an inline conditional branch at the deletion call site. This doesn't work because extern_weak only works on MachO if you have some archive providing the default value of the extern_weak symbol. Arranging to provide such an archive has the same challenges as providing the symbol in the standard library. Not to mention that extern_weak doesn't really work on COFF.

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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@228601 91177308-0d34-0410-b5e6-96231b3b80d8

* Add the hostname to the module hash to avoid sharing between hostsBen Langmuir2015-02-091-0/+10
| | | | | | | Sharing between hosts will cause problems for the LockFileManager, which can timeout waiting for a process that has already died. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@228592 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow to specify multiple -fsanitize-blacklist= arguments.Alexey Samsonov2015-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Allow user to provide multiple blacklists by passing several -fsanitize-blacklist= options. These options now don't override default blacklist from Clang resource directory, which is always applied (which fixes PR22431). -fno-sanitize-blacklist option now disables all blacklists that were specified earlier in the command line (including the default one). This change depends on http://reviews.llvm.org/D7367.

* Process the -fno-signed-zeros optimization flag (PR20870)Sanjay Patel2015-01-231-1/+1
| | | | | | | | | | | | | | | | | | | | The driver currently accepts but ignores the -fno-signed-zeros flag. This patch passes the flag through and enables 'nsz' fast-math-flag generation in IR. The existing OpenCL flag for the same functionality is made into an alias here. It may be removed in a subsequent patch. This should resolve bug 20870 ( http://llvm.org/bugs/show_bug.cgi?id=20870 ); patches for the optimizer were checked in at: http://llvm.org/viewvc/llvm-project?view=revision&revision=225050 http://llvm.org/viewvc/llvm-project?view=revision&revision=224583 Differential Revision: http://reviews.llvm.org/D6873 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@226915 91177308-0d34-0410-b5e6-96231b3b80d8

* [cleanup] Re-sort *all* #include lines with llvm/utils/sort_includes.pyChandler Carruth2015-01-141-1/+1
| | | | | | | | | | Sorry for the noise, I managed to miss a bunch of recent regressions of include orderings here. This should actually sort all the includes for Clang. Again, no functionality changed, this is just a mechanical cleanup that I try to run periodically to keep the #include lines as regular as possible across the project. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@225979 91177308-0d34-0410-b5e6-96231b3b80d8
