2013-02-12Have the bitcode writer and reader handle the new attribute references.Bill Wendling
The bitcode writer emits a reference to the attribute group that the object at the given index refers to. The bitcode reader is modified to read this in and map it back to the attribute group. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174952 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-12Check type for legality before forming a select from loads.Pete Cooper
Sorry for the lack of a test case. I tried writing one for i386 as i know selects are illegal on this target, but they are actually considered legal by isel and expanded later. I can't see any targets to trigger this, but checking for the legality of a node before forming it is general goodness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174934 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-11BBVectorize: Don't over-search when building the dependency mapHal Finkel
When building the pairable-instruction dependency map, don't search past the last pairable instruction. For large blocks that have been divided into multiple instruction groups, searching past the last instruction in each group is very wasteful. This gives a 32% speedup on the csa.ll test case from PR15222 (when using 50 instructions in each group). No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174915 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-11BBVectorize: Omit unnecessary entries in PairableInstUsersHal Finkel
This map is queried only for instructions in pairs of pairable instructions; so make sure that only pairs of pairable instructions are added to the map.

2013-02-11R600/SI: Use V_ADD_F32 instead of V_MOV_B32 for clamp/neg/abs modifiers.Michel Danzer
The modifiers don't seem to have any effect with V_MOV_B32, supposedly it's meant to just move bits untouched. Fixes 46 piglit tests with radeonsi, though unfortunately 11 of those had just regressed because they started using the clamp modifier. NOTE: This is a candidate for the Mesa stable branch.

2013-02-11[asan] added a flag -mllvm asan-short-64bit-mapping-offset=1 (0 by default)Kostya Serebryany
This flag makes asan use a small (<2G) offset for 64-bit asan shadow mapping. On x86_64 this saves us a register, thus achieving ~2/3 of the zero-base-offset's benefits in both performance and code size. Thanks Jakub Jelinek for the idea. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174886 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-11AArch64: fix build on some MSVC versionsTim Northover
This does two things: It removes a call to abs() which may have "long long" parameter on Windows, which is not necessarily available in C++03. It also corrects the signedness of Amount, which was relying on implementation-defined conversions previously. Code was already tested (albeit in an implemnetation defined way) so no extra tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174885 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-11Make use of DiagnosticType to provide better AArch64 diagnostics.Tim Northover
This gives a DiagnosticType to all AsmOperands in sight. This replaces all "invalid operand" diagnostics with something more specific. The messages given should still be sufficiently vague that they're not usually actively misleading when LLVM guesses your instruction incorrectly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174871 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-11Add support for updating LiveIntervals to ↵Cameron Zwarich
MachineBasicBlock::SplitCriticalEdge(). This is currently a bit hairier than it needs to be, since depending on where the split block resides the end ListEntry of the split block may be the end ListEntry of the original block or a new entry. Some changes to the SlotIndexes updating should make it possible to eliminate the two cases here. This also isn't as optimized as it could be. In the future Liveinterval should probably get a flag that indicates whether the LiveInterval is within a single basic block. We could ignore all such intervals when splitting an edge. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174870 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-11Add support for printing out the attribute groups.Bill Wendling
This emits the attribute groups that are used by the functions. (It currently doesn't print out return type or parameter attributes within attribute groups.) Note: The functions still retrieve their attributes from the "old" bitcode format (using the deprecated 'Raw()' method). This means that string attributes within an attribute group will not show up during a disassembly. This will be addressed in a future commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174867 91177308-0d34-0410-b5e6-96231b3b80d8
