* Fix linking of unnamed_addr.Rafael Espindola2013-09-041-2/+6
| | | | | | | | This was regression from r134829. When linking we have to be conservative. If one of the symbols has a significant address, then the result should have it too. llvm-svn: 189935
* InstCombine: allow unmasked icmps to be combined with logical opsTim Northover2013-09-041-9/+29
| | | | | | | | | | "(icmp op i8 A, B)" is equivalent to "(icmp op i8 (A & 0xff), B)" as a degenerate case. Allowing this as a "masked" comparison when analysing "(icmp) &/| (icmp)" allows us to combine them in more cases. rdar://problem/7625728 llvm-svn: 189931
* InstCombine: look for masked compares with subset relationTim Northover2013-09-041-11/+75
| | | | | | | | | | | Even in cases which aren't universally optimisable like "(A & B) != 0 && (A & C) != 0", the masks can make one of the comparisons completely redundant. In this case, since we've gone to the effort of spotting masked comparisons we should combine them. rdar://problem/7625728 llvm-svn: 189930

* Revert "Revert "Remove the darwin gdb option, that version of gdb is now ↵Michael Gottesman2013-09-042-36/+7

I am going to XFAIL the failing test since it is using what Eric described as "the member hack" which was needed on that old GDB. Sorry for the noise! llvm-svn: 189914

* Add llvm namespace to llvm::next.Michael Gottesman2013-09-041-2/+2

* Use llvm::next() instead of incrementing begin iterators of std::vector.Michael Gottesman2013-09-041-2/+2
| | | | | | | | | | Iterator of std::vector may be implemented as a raw pointer. In this case begin iterators are rvalues and cannot be incremented. For example, this is the case with STDCXX implementation of vector. Patch by Konstantin Tokarev <annulen@yandex.ru>. llvm-svn: 189911

* Add r159136 back now that pr13124 has been fixed.Rafael Espindola2013-09-031-0/+11
| | | | | | | | | | Original message: If a constant or a function has linkonce_odr linkage and unnamed_addr, mark hidden. Being linkonce_odr guarantees that it is available in every dso that needs it. Being a constant/function with unnamed_addr guarantees that the copies don't have to be merged. llvm-svn: 189886
* X86: Mark non-crashing report_fatal_errors() as such.Jim Grosbach2013-09-031-13/+19
| | | | | | | | | Previously, the clang crash handling code would kick in and give a crash report for these, even though they're not that sort of error. rdar://14882264 llvm-svn: 189878

* [objc-arc] Turn off the objc_retainBlock -> objc_retain optimization.Michael Gottesman2013-09-031-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reason that I am turning off this optimization is that there is an additional case where a block can escape that has come up. Specifically, this occurs when a block is used in a scope outside of its current scope. This can cause a captured retainable object pointer whose life is preserved by the objc_retainBlock to be deallocated before the block is invoked. An example of the code needed to trigger the bug is: ---- \#import <Foundation/Foundation.h> int main(int argc, const char * argv[]) { void (^somethingToDoLater)(); { NSObject *obj = [NSObject new]; somethingToDoLater = ^{ [obj self]; // Crashes here }; } NSLog(@"test."); somethingToDoLater(); return 0; } ---- In the next commit, I remove all the dead code that results from this. Once I put in the fixing commit I will bring back the tests that I deleted in this commit. rdar://14802782. rdar://14868830. llvm-svn: 189869

* Teach InstCombineLoadCast about address spaces.Matt Arsenault2013-09-031-2/+2

* Revert "Revert "ARM: Improve pattern for isel mul of vector by scalar.""Jim Grosbach2013-09-031-0/+11
| | | | | | | | | This reverts commit r189648. Fixes for the previously failing clang-side arm_neon_intrinsics test cases will be checked in separately. llvm-svn: 189841
* Add the rest of the stock attributes to the attribute table.Eric Christopher2013-09-032-6/+240
| | | | | | | | This won't affect the kinds of hashes we test for as we actually do hashing based on form and attribute. Change the fission-hash testcase one last time to handle DW_AT_comp_dir. llvm-svn: 189840
* In this patch we are trying to do two things:Yi Jiang2013-09-031-11/+36
| | | | | | | | | 1) If the width of vectorization list candidate is bigger than vector reg width, we will break it down to fit the vector reg. 2) We do not vectorize the width which is not power of two. The performance result shows it will help some spec benchmarks. mesa improved 6.97% and ammp improved 1.54%. llvm-svn: 189830
* [SystemZ] Add support for TMHH, TMHL, TMLH and TMLLRichard Sandiford2013-09-032-8/+107
| | | | | | | | | For now this just handles simple comparisons of an ANDed value with zero. The CC value provides enough information to do any comparison for a 2-bit mask, and some nonzero comparisons with more populated masks, but that's all future work. llvm-svn: 189819

* Revert 189756 for now, it doesn't match what rdar://14871821 really wants.Tilmann Scheller2013-09-021-7/+2
| | | | | | What we really want is to enable Swift by default for *v7s triples (and there already seems to be some logic which attempts to do that). In that case the iOS version doesn't matter. llvm-svn: 189763
* ARM: Default to Swift when compiling for iOS 6 or later.Tilmann Scheller2013-09-021-2/+7

* llvm interpreter: select, shuffle and insertelement instructions.Elena Demikhovsky2013-09-023-8/+156
| | | | | | | | | This patch implements vector support for select instruction and adds specific vector instructions : shuffle and insertelement. (tests are also included) and functions lle_X_memset, lle_X_memcpy added. Done by Veselov, Yuri (mailto:Yuri.Veselov@intel.com) llvm-svn: 189735
* Fix some rather confusing indentation and control flow in the errnoChandler Carruth2013-09-021-15/+14
| | | | | | | | | | | | | printing routine. This is made harder to see due to the surprising formatting, inconsistent brace usage, and repeated conditions that all test the same thing. The only "consequence" of this bug is re-assigning 'str' to an empty string when computing the error string for an error number of 0 in the event of a non-GNU strerror_r routine. So, nothing to see here other than cleanup. It did help me find PR17055 in clang-format though. llvm-svn: 189734

* Make sure we don't generate stubs for any of these functions because theyReed Kotler2013-09-011-2/+21
| | | | | | | | | don't exist in libc. This is really not the right way to solve this problem; but it's not clear to me at this time exactly what is the right way. If we create stubs here, they will cause link errors because these functions do not exist in libc. llvm-svn: 189727

* Fix my previous checkin to updatePressureDiffs.Andrew Trick2013-08-311-4/+19
| | | | | | | | There was one case that we could hit a DebugValue where I didn't think to check. DebugValues are evil. No checkinable test case, sorry. It's an obvious fix. llvm-svn: 189717
* [PowerPC] Fast-isel cleanup patch.Bill Schmidt2013-08-311-20/+37
| | | | | | | | | | | | | | | | | | | | Here are a few miscellaneous things to tidy up the PPC64 fast-isel implementation. I corrected a couple of commentary lapses, and added documentation of future opportunities. I also implemented TargetMaterializeAlloca, which I somehow forgot when I split up the original huge patch. Finally, I decided to delete SelectCmp. I hadn't previously hooked it in to TargetSelectInstruction(), and when I did I realized it wasn't serving any useful purpose. This is only useful for compares that don't feed a branch in the same block, and to handle that we would have to have logic to interpret i1 as a condition register. This could probably be done, but would require Unseemly Hackery, and honestly does not seem worth the hassle. This ends the current patch series. llvm-svn: 189715
* [PowerPC] Add integer truncation support to fast-isel.Bill Schmidt2013-08-301-0/+31
| | | | | | | | | | | | This is the last substantive patch I'm planning for fast-isel in the near future, adding fast selection of integer truncates. There are certainly more things that can be improved (many of which are called out in FIXMEs), but for now we are catching most of the important cases. I'll document some of the remaining work in a cleanup patch shortly. llvm-svn: 189706

| | | | llvm-svn: 189705
* [PowerPC] Call support for fast-isel.Bill Schmidt2013-08-303-3/+338
| | | | | | | | | This patch adds fast-isel support for calls (but not intrinsic calls or varargs calls). It also removes a badly-formed assert. There are some new tests just for calls, and also for folding loads into arguments on calls to avoid extra extends. llvm-svn: 189701
