No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173809 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-29AttributeSet::get(): Fix a valgrind error. It doesn't affect actual ↵NAKAMURA Takumi

2013-01-29Fix 64-bit atomic operations in Thumb mode.Tim Northover
The ARM and Thumb variants of LDREXD and STREXD have different constraints and take different operands. Previously the code expanding atomic operations didn't take this into account and asserted in Thumb mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173780 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-29Fixed some whitespace/80+ violations. Also added a space after a namespace ↵Michael Gottesman
declaration. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173772 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Added missing dashes from header declaration comment.Michael Gottesman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173770 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Juggled Debug.h from ObjCARC.h to only the including cpp files thatMichael Gottesman
actually have DEBUG statements. Also changed raw_ostream in said header to be a forward declaration (removing an include). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173769 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173767 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Added two missing headers from ObjCARCAliasAnalysis.h.Michael Gottesman
This was missed since whenever I was including ObjCARCAliasAnalysis.h, I was including ObjCARC.h before it which included these includes (resulting in no compilation breakage). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173764 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Removed InstCombine/Targets as library dependencies for libObjCARCOpts since ↵Michael Gottesman
they are unnecessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173763 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Convert getAttributes() to return an AttributeSetNode.Bill Wendling
The AttributeSetNode contains all of the attributes. This removes one (hopefully last) use of the Attribute class as a container of multiple attributes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173761 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Extracted ObjCARCContract from ObjCARCOpts into its own file.Michael Gottesman
This also required adding 2x headers Dependency Analysis.h/Provenance Analysis.h and a .cpp file DependencyAnalysis.cpp to unentangle the dependencies inbetween ObjCARCContract and ObjCARCOpts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173760 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Removed some cruft from ObjCARCAliasAnalysis.cpp.Michael Gottesman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173759 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Teach SDISel to combine fsin / fcos into a fsincos node if the followingEvan Cheng
conditions are met: 1. They share the same operand and are in the same BB. 2. Both outputs are used. 3. The target has a native instruction that maps to ISD::FSINCOS node or the target provides a sincos library call. Implemented the generic optimization in sdisel and enabled it for Mac OSX. Also added an additional optimization for x86_64 Mac OSX by using an alternative entry point __sincos_stret which returns the two results in xmm0 / xmm1. rdar://13087969 PR13204 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173755 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29Use an AttrBuilder to generate the correct AttributeSet.Bill Wendling
We no longer accept an encoded integer as representing all of the attributes. Convert this via the AttrBuilder class into an AttributeSet with the correct representation (an AttributeSetImpl that holds a list of Attribute objects). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173750 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-29Unroll again after running BBVectorizeHal Finkel
Because BBVectorize may significantly shorten a loop body, unroll again after vectorization. This is especially important when using runtime or partial unrolling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173730 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-28Try to appease some broken compilers by using 'unsigned' instead of 'uint64_t'.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173725 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-28Avoid Unnecessary BuildsDavid Greene
By default, stop the universe build if a key component fails. This avoids useless builds when we know a package is broken anyway. Provide a --keep-going option to override this behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173723 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-28Remove the AttributeWithIndex class.Bill Wendling
The AttributeWithIndex class exposed the interior structure of the AttributeSet class. That was gross. Remove it and all of the code that relied upon it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173722 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-28Fix gcc/printf/ISO C++ warningEdwin Vane
Remove the use of the 't' length modifier to avoid a gcc warning. Based on usage, 32 bits of precision is good enough for printing a stack offset for a stack trace. 't' length modifier isn't in C++03 but it *is* in C++11. Added a FIXME to reintroduce once LLVM makes the switch to C++11. Reviewer: gribozavr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173711 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-28This patch addresses bug 15031.Bill Schmidt
The common code in the post-RA scheduler to break anti-dependencies on the critical path contained a flaw. In the reported case, an anti-dependency between the overlapping registers %X4 and %R4 exists: %X29<def> = OR8 %X4, %X4 %R4<def>, %X3<def,dead,tied3> = LBZU 1, %X3<kill,tied1> The unpatched code breaks the dependency by replacing %R4 and its uses with %R3, the first register on the available list. However, %R3 and %X3 overlap, so this creates two overlapping definitions on the same instruction. The fix is straightforward, preventing selection of a register that overlaps any other defined register on the same instruction. The test case is reduced from the bug report, and verifies that we no longer produce "lbzu 3, 1(3)" when breaking this anti-dependency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173706 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-28[msan] Mostly disable msan-handle-icmp-exact.Evgeniy Stepanov
It is way too slow. Change the default option value to 0. Always do exact shadow propagation for unsigned ICmp with constants, it is cheap (under 1% cpu time) and required for correctness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173682 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-28A bugfix for tblgen, in the function ‘emitSourceFileHeader’.Nadav Rotem
When the first parameter (‘Desc’) is more than 80 characters long, it will result the header line that contains the description to be more Than (4GB!) long. Not only it takes forever to produce, the output file cannot be open, since its ginormous. Patch by Elior Malul. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173672 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-28Rewrite the removeAttr() method.Bill Wendling
This now uses the AttributeSet object instead of the Attribute / AttributeWithIndex objects. It's fairly simple now. It goes through all of the subsets before the one we're modifying, adds them to the new set. It then adds the modified subset (with the requested attributes removed). And then adds the rest of the subsets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173660 91177308-0d34-0410-b5e6-96231b3b80d8
