* Fix handling of %% format specifier in os_log builtins.Mehdi Amini2016-10-251-8/+19
| | | | | | | Returning `false` was stopping the parsing of further arguments, which wasn't intended. llvm-svn: 285047
* test/CodeGen/builtins.c: reinstate #ifdef __x86_64__ around __builtin_longjmpMehdi Amini2016-10-241-0/+5
| | | | | | Unadvertently removed in r285019 llvm-svn: 285041
* Fix test on non-X86 platformsMehdi Amini2016-10-241-0/+5
| | | | | | | This is a fixup for r285019, adding an `#ifdef __x86_64__` since the os_log builtin is platform specific. llvm-svn: 285027
* Add support for __builtin_os_log_format[_buffer_size]Mehdi Amini2016-10-241-3/+138
| | | | | | | | | | | | | | | | | This reverts commit r285007 and reapply r284990, with a fix for the opencl test that I broke. Original commit message follows: These new builtins support a mechanism for logging OS events, using a printf-like format string to specify the layout of data in a buffer. The _buffer_size version of the builtin can be used to determine the size of the buffer to allocate to hold the data, and then __builtin_os_log_format can write data into that buffer. This implements format checking to report mismatches between the format string and the data arguments. Most of this code was written by Chris Willmore.

* Convert finite to builtinDehao Chen2016-09-141-0/+4
| | | | | | | | | | | | Summary: This patch converts finite/__finite to builtin functions so that it will be inlined by compiler. Reviewers: hfinkel, davidxl, efriedma Subscribers: efriedma, llvm-commits Differential Revision: https://reviews.llvm.org/D24483 llvm-svn: 281509
* Emit more intrinsics for builtin functionsMatt Arsenault2016-07-011-0/+92
| | | | | | | | | | | | This is important for building libclc. Since r273039 tests are failing due to now emitting calls to these functions instead of emitting the DAG node. The libm function names are implemented for OpenCL, and should call the locally defined versions, so -fno-builtin is used. The IR Some functions use the __builtins and expect the intrinsics to be emitted. Without this we end up with nobuiltin calls to intrinsics or to unsupported library calls. llvm-svn: 274370
* make __builtin_isfinite more efficient (PR27145)Sanjay Patel2016-04-071-3/+1
| | | | | | | | | | | | | | isinf (is infinite) and isfinite should be implemented with the same function except we change the comparison operator. See PR27145 for more details: https://llvm.org/bugs/show_bug.cgi?id=27145 Ref: forked off of the discussion in D18513. Differential Revision: http://reviews.llvm.org/D18648 llvm-svn: 265675

| | | | | | | Follow the naming convention that bswap uses since it's a similar sort of operation. llvm-svn: 259671
* [Modules] Implement __builtin_isinf_sign in Clang.Chandler Carruth2015-03-191-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Somehow, we never managed to implement this fully. We could constant fold it like crazy, including constant folding complex arguments, etc. But if you actually needed to generate code for it, error. I've implemented it using the somewhat obvious lowering. Happy for suggestions on a more clever way to lower this. Now, what you might ask does this have to do with modules? Fun story. So it turns out that libstdc++ actually uses __builtin_isinf_sign to implement std::isinf when in C++98 mode, but only inside of a template. So if we're lucky, and we never instantiate that, everything is good. But once we try to instantiate that template function, we need this builtin. All of my customers at least are using C++11 and so they never hit this code path. But what does that have to do with modules? Fun story. So it turns out that with modules we actually observe a bunch of bugs in libstdc++ where their <cmath> header clobbers things exposed by <math.h>. To fix these, we have to provide global function definitions to replace the macros that C99 would have used. And it turns out that ::isinf needs to be implemented using the exact semantics used by the C++98 variant of std::isinf. And so I started to fix this bug in libstdc++ and ceased to be able to compile libstdc++ with Clang. The yaks are legion. llvm-svn: 232778
* Fix test/CodeGen/builtins.c for platforms that don't lower sjljReid Kleckner2015-03-041-0/+3
| | | | | | | | Opt in Win64 to supporting sjlj lowering. We have the backend lowering, so I think this was just an oversight because WinX86_64TargetCodeGenInfo doesn't inherit from X86_64TargetCodeGenInfo. llvm-svn: 231280
* Lower __builtin_fabs* to @llvm.fabs.*Reid Kleckner2014-11-031-0/+7
| | | | | | | | | mingw64's headers implement fabs by calling __builtin_fabs, so using the library call results in an infinite loop. If the backend legalizes @llvm.fabs as a call to fabs later, things should work out, as the crt provides a definition. llvm-svn: 221206
* CGBuiltin: Use frem instruction rather than libcall to implement fmodJan Vesely2014-09-261-0/+16
| | | | | | | | AFAICT the semantics of frem match libm's fmod. Signed-off-by: Jan Vesely <jan.vesely@rutgers.edu> Reviewed-by: Tom Stellard <tom@stellard.net> llvm-svn: 218488
* CGBuiltin: Use @llvm.fabs rather than fabs libcall when emitting builtinsTom Stellard2014-09-031-5/+5
| | | | | | | | | | | Using the intrinsic allows the SelectionDAGBuilder to turn this call into the FABS Node and also the intrinsic is something the vectorizer knows how to vectorize. This patch also sets the readnone attribute on this call, which should enable additional optmizations. llvm-svn: 217042

* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446
