* 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
* CHECK-LABEL-ify some code gen tests to improve diagnostic experience when ↵Stephen Lin2013-08-151-4/+4
| | | | | | tests fail. llvm-svn: 188447
* Expose __builtin_bswap16.Benjamin Kramer2012-10-061-0/+1
| | | | | | | GCC has always supported this on PowerPC and 4.8 supports it on all platforms, so it's a good idea to expose it in clang too. LLVM supports this on all targets. llvm-svn: 165362
* Add __builtin_readcyclecounter() to produce the @llvm.readcyclecounter() ↵Hal Finkel2012-08-051-0/+6

* Enable the implementation of __builtin_setjmp and __builtin_longjmp. Not allJohn McCall2010-05-271-0/+7
| | | | | | LLVM backends support these yet. llvm-svn: 104867
* Implement codegen for __builtin_isnormal.Benjamin Kramer2010-05-191-0/+8

* optimize builtin_isnan/isinf to not do an extraneous extension fromChris Lattner2010-05-061-0/+18
| | | | | | | float -> double (which happens because they are modelled as int(...) functions), and add a testcase for isinf. llvm-svn: 103167
* PR6515: Implement __builtin_signbit and friends.Eli Friedman2010-03-061-0/+1
| | | | | | | I'm reasonably sure my implementation is correct, but it would be nice if someone could double-check. llvm-svn: 97864
* Revert changes r97693, r97700, and r97718.John McCall2010-03-041-7/+0
| | | | | | Our testing framework can't deal with disabled targets yet. llvm-svn: 97719

* Support constant-evaluation of __builtin_nans* as well as the correct constantJohn McCall2010-02-281-3/+42
| | | | | | | | evaluation of __builtin_nan*. Most of the work to make this work is in LLVM. Fixes <rdar://problem/7696712> and part of PR 5255. llvm-svn: 97383
* 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
* Don't #include <stdio.h> when tests don't need it, or use clang instead of ↵Daniel Dunbar2009-11-171-1/+1
