* Support for -Wa,-compress-debug-sections.David Blaikie2014-03-271-0/+1

* Move the -i[no-]system-prefix options from CC1Options.td to Options.td.Alexander Kornienko2014-03-261-4/+4
| | | | | | | | | | | | | | | | Summary: This allows them to be used without -cc1 the same way as -I and -isystem. Renamed the options to --system-header-prefix=/--no-system-header-prefix to avoid interference with -isystem and make the intent of the option cleaner.

* Creating a printing policy for "half":Yunzhong Gao2014-03-181-0/+3
| | | | | | | | | | | | Since "half" is an OpenCL keyword and clang accepts __fp16 as an extension for other languages, error messages and metadata (and hence debug info) should refer to the half-precision floating point as "__fp16" instead of "half" when compiling for non-OpenCL languages. This patch creates a new printing policy for half in a similar manner to what is done for bool and wchar_t. Differential Revision: http://llvm-reviews.chandlerc.com/D2952 llvm-svn: 204164

* MS ABI: Implement #pragma vtordisp() and clang-cl /vdNReid Kleckner2014-02-121-0/+1
| | | | | | | | | | | | | | | | | These features are new in VS 2013 and are necessary in order to layout std::ostream correctly. Currently we have an ABI incompatibility when self-hosting with the 2013 stdlib in our convertible_fwd_ostream wrapper in gtest. This change adds another implicit attribute, MSVtorDispAttr, because implicit attributes are currently the best way to make sure the information stays on class templates through instantiation.

* Add an option to allow Clang verify source files for a module only once duringDmitri Gribenko2014-02-121-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | the build When Clang loads the module, it verifies the user source files that the module was built from. If any file was changed, the module is rebuilt. There are two problems with this: 1. correctness: we don't verify system files (there are too many of them, and stat'ing all of them would take a lot of time); 2. performance: the same module file is verified again and again during a single build. This change allows the build system to optimize source file verification. The idea is based on the fact that while the project is being built, the source files don't change. This allows us to verify the module only once during a single build session. The build system passes a flag, -fbuild-session-timestamp=, to inform Clang of the time when the build started. The build system also requests to enable this feature by passing -fmodules-validate-once-per-build-session. If these flags are not passed, the behavior is not changed. When Clang verifies the module the first time, it writes out a timestamp file. Then, when Clang loads the module the second time, it finds a timestamp file, so it can compare the verification timestamp of the module with the time when the build started. If the verification timestamp is too old, the module is verified again, and the timestamp file is updated. llvm-svn: 201224

* [asan] Remove -fsanitize-address-zero-base-shadow command lineEvgeniy Stepanov2014-01-161-2/+0
| | | | | | | | | | | | | | | | flag from clang, and disable zero-base shadow support on all platforms where it is not the default behavior. - It is completely unused, as far as we know. - It is ABI-incompatible with non-zero-base shadow, which means all objects in a process must be built with the same setting. Failing to do so results in a segmentation fault at runtime. - It introduces a backward dependency of compiler-rt on user code, which is uncommon and complicates testing. This is the Clang part of a larger change. llvm-svn: 199372
* Remove the -cxx-abi command-line flag.Hans Wennborg2014-01-141-8/+1
| | | | | | | | | | | | | | | This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

* Switch around the order of MSVCCompat and MicrosoftExtAlp Toker2014-01-141-2/+1
| | | | | | | | | | | | Full language modes usually get listed before minor language extensions in LangOpts, so that subsequent sub-modes can predicate on the major modes. This also lends to a cleanup in CompilerInvocation to better indicate to the reader that MSVCCompat is a superset of MicrosoftExt. Cleanup only. llvm-svn: 199210
* Rename language option MicrosoftMode to MSVCCompatAlp Toker2014-01-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | There's been long-standing confusion over the role of these two options. This commit makes the necessary changes to differentiate them clearly, following up from r198936. MicrosoftExt (aka. fms-extensions): Enable largely unobjectionable Microsoft language extensions to ease portability. This mode, also supported by gcc, is used for building software like FreeBSD and Linux kernel extensions that share code with Windows drivers. MSVCCompat (aka. -fms-compatibility, formerly MicrosoftMode): Turn on a special mode supporting 'heinous' extensions for drop-in compatibility with the Microsoft Visual C++ product. Standards-compilant C and C++ code isn't guaranteed to work in this mode. Implies MicrosoftExt. Note that full -fms-compatibility mode is currently enabled by default on the Windows target, which may need tuning to serve as a reasonable default. See cfe-commits for the full discourse, thread 'r198497 - Move MS predefined type_info out of InitializePredefinedMacros' No change in behaviour. llvm-svn: 199209
* Use the MS ABI for Win32 targets by defaultHans Wennborg2014-01-131-2/+5
| | | | | | | | | | In addition to being a sensible default, this is a huge improvement in test coverage for the MS ABI: any bot that targets Win32 will now run the test suite using the MS ABI by default. Differential Revision: http://llvm-reviews.chandlerc.com/D2401 llvm-svn: 199131
* Implement a new -fstandalone-debug option. rdar://problem/15685848Adrian Prantl2014-01-071-8/+14
| | | | | | | | | | | | | | It controls everything that -flimit-debug-info used to, plus the vtable type optimization. The old -fno-limit-debug-info option is now an alias to -fstandalone-debug and vice versa. Standalone is the default on Darwin until dtrace is updated to work with non-standalone debug info (rdar://problem/15758808). Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind because NoStandaloneDebugInfo sounded even more confusing. llvm-svn: 198655

* Add -freroll-loops to enable loop rerollingHal Finkel2013-11-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds -freroll-loops (and -fno-reroll-loops in the usual way) to enable loop rerolling as part of the optimization pass manager. This transformation can enable vectorization, reduce code size (or both). Briefly, loop rerolling can transform a loop like this: for (int i = 0; i < 3200; i += 5) { a[i] += alpha * b[i]; a[i + 1] += alpha * b[i + 1]; a[i + 2] += alpha * b[i + 2]; a[i + 3] += alpha * b[i + 3]; a[i + 4] += alpha * b[i + 4]; } into this: for (int i = 0; i < 3200; ++i) { a[i] += alpha * b[i]; } Loop rerolling is currently disabled by default at all optimization levels. llvm-svn: 194967

| | | | | | | | | | | | | | | | | | | | | | | | Trying to fix test failures since earlier today. One of the tests added in this commit is outputting test/Driver/clang_f_opts.s which the builders that build in-tree (eg. clang-native-arm-cortex-a9) are trying to run as a test case, causing failures. clang_f_opts.c: If -### doesn't emit the warning then this test probably shouldn't be in here in the first place. Frontend maybe? invalid-o-level.c: Running %clang_cc1 in the Driver tests doesn't make sense because -cc1 bypasses the driver. (I'm not reverting the commit that introduced this but please fix instead of keeping it this way.) Reverting to fix the build failures and also so that the tests can be thought out more thoroughly.
