* [CUDA][HIP] Do not emit type info when compiling for deviceYaxun Liu2018-06-051-1/+1
| | | | | | | | | | | | | CUDA/HIP does not support RTTI on device side, therefore there is no point of emitting type info when compiling for device. Emitting type info for device not only clutters the IR with useless global variables, but also causes undefined symbol at linking since vtable for cxxabiv1::class_type_info has external linkage.

* CodeGen: Emit string literal in constant address spaceYaxun Liu2018-05-141-6/+41
| | | | | | | | | Some targets have constant address space (e.g. amdgcn). For them string literal should be emitted in constant address space then casted to default address space. Differential Revision: https://reviews.llvm.org/D46643 llvm-svn: 332279
* [Clang] Implement function attribute no_stack_protector.Manoj Gupta2018-05-091-6/+8
| | | | | | | | | | | | | | | | | | | | | | Summary: This attribute tells clang to skip this function from stack protector when -stack-protector option is passed. GCC option for this is: __attribute__((__optimize__("no-stack-protector"))) and the equivalent clang syntax would be: __attribute__((no_stack_protector)) This is used in Linux kernel to selectively disable stack protector in certain functions.

* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-091-1/+1
| | | | | | | | | | | | | | | | | | | This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* [c++2a] [concepts] Add rudimentary parsing support for template concept ↵Faisal Vali2018-04-251-0/+1
| | | | | | | | | | | | | | declarations This patch is a tweak of changyu's patch: https://reviews.llvm.org/D40381. It differs in that the recognition of the 'concept' token is moved into the machinery that recognizes declaration-specifiers - this allows us to leverage the attribute handling machinery more seamlessly. See the test file to get a sense of the basic parsing that this patch supports. There is much more work to be done before concepts are usable... Thanks Changyu! llvm-svn: 330794

* [CodeGen] Add an option to suppress output of llvm.identMikhail Maltsev2018-04-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | Summary: By default Clang outputs its version (including git commit hash, in case of trunk builds) into object and assembly files. It might be useful to have an option to disable this, especially for debugging purposes. This patch implements new command line flags -Qn and -Qy (the names are chosen for compatibility with GCC). -Qn disables output of the 'llvm.ident' metadata string and the 'producer' debug info. -Qy (enabled by default) does the opposite.

* Implement proper support for `-falign-functions`Saleem Abdulrasool2018-04-191-0/+4
| | | | | | | | | | | | | | | | This implements support for the previously ignored flag `-falign-functions`. This allows the frontend to request alignment on function definitions in the translation unit where they are not explicitly requested in code. This is compatible with the GCC behaviour and the ICC behaviour. The scalar value passed to `-falign-functions` aligns functions to a power-of-two boundary. If flag is used, the functions are aligned to 16-byte boundaries. If the scalar is specified, it must be an integer less than or equal to 4096. If the value is not a power-of-two, the driver will round it up to the nearest power of two. llvm-svn: 330378
* Add a command line option 'fregister_global_dtors_with_atexit' toAkira Hatanaka2018-04-171-0/+6

Register destructor functions annotated with __attribute__((destructor)) calling __cxa_atexit in a synthesized constructor function instead of emitting references to the functions in a special section. The primary reason for adding this option is that we are planning to deprecate the __mod_term_funcs section on Darwin in the future. This feature is enabled by default only on Darwin. Users who do not want this can use command line option 'fno_register_global_dtors_with_atexit' to disable it. rdar://problem/33887655 Differential Revision: https://reviews.llvm.org/D45578 llvm-svn: 330199

* [XRay][clang] Add flag to choose instrumentation bundlesDean Michael Berris2018-04-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change addresses http://llvm.org/PR36926 by allowing users to pick which instrumentation bundles to use, when instrumenting with XRay. In particular, the flag `-fxray-instrumentation-bundle=` has four valid values: - `all`: the default, emits all instrumentation kinds - `none`: equivalent to -fnoxray-instrument - `function`: emits the entry/exit instrumentation - `custom`: emits the custom event instrumentation These can be combined either as comma-separated values, or as repeated flag values.

* [MS] Always use base dtors in place of complete/vbase dtors when possibleReid Kleckner2018-03-161-13/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously we tried too hard to uphold the fiction that destructor variants work like they do on Itanium throughout the ABI-neutral parts of clang. This lead to MS C++ ABI incompatiblities and other bugs. Now, -mconstructor-aliases will no longer control this ABI detail, and clang -cc1's LLVM IR output will be this much closer to the clang driver's. Based on a patch by Zahira Ammarguellat: https://reviews.llvm.org/D39063 I've tried to move the logic that Zahira added into MicrosoftCXXABI.cpp. There is only one ABI-specific detail sticking out, and that is in CodeGenModule::getAddrOfCXXStructor, where we collapse complete dtors to base dtors in the MS ABI.

* Set dso_local on external rtti GVs.Rafael Espindola2018-03-141-2/+3
| | | | | | | | | | | In this particular case it would be possible to just add an else with CGM.setDSOLocal(GV), but it seems better to have as many callers as possible just call setGVProperties so that we can centralize the logic there. This patch then makes setGVProperties able to handle null Decls. llvm-svn: 327543
* Always set dso_local in CodeGenModule::setDSOLocal.Rafael Espindola2018-03-021-2/+7
| | | | | | | | | | | | | This shouldn't change any results for now, but is more consistent with how we set dllimport/dllexport and will make future changes easier. Since clang produces IR as it parses, it can find out mid file that something is dllimport. When that happens we have to drop dso_local. This is not a problem right now because CodeGenModule::setDSOLocal is called from relatively few places at the moment. llvm-svn: 326527
* Remove redundant casts. NFCGeorge Burgess IV2018-03-011-1/+1
| | | | | | | | | | | | | | | | | | | So I wrote a clang-tidy check to lint out redundant `isa`, `cast`, and `dyn_cast`s for fun. This is a portion of what it found for clang; I plan to do similar cleanups in LLVM and other subprojects when I find time. Because of the volume of changes, I explicitly avoided making any change that wasn't highly local and obviously correct to me (e.g. we still have a number of foo(cast<Bar>(baz)) that I didn't touch, since overloading is a thing and the cast<Bar> did actually change the type -- just up the class hierarchy). I also tried to leave the types we were cast<>ing to somewhere nearby, in cases where it wasn't locally obvious what we were dealing with before. llvm-svn: 326416
