2009-04-28Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want toBill Wendling
use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'm not 100% sure if it's necessary to change it there... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70270 91177308-0d34-0410-b5e6-96231b3b80d8

PR2957 ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes as the shuffle mask. A value of -1 represents UNDEF. In addition to eliminating the creation of illegal BUILD_VECTORS just to represent shuffle masks, we are better about canonicalizing the shuffle mask, resulting in substantially better code for some classes of shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70225 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Do not share a single unknown val# for all the live ranges merged into a ↵Evan Cheng
physical sub-register live interval. When coalescer is merging in clobbered virtaul register live interval into a physical register live interval, give each virtual register val# a separate val# in the physical register live interval. Otherwise, the coalescer would have lost track of the definitions information it needs to make correct coalescing decisions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70026 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-21It has finally happened. Spiller is now using live interval info.Evan Cheng
This fixes a very subtle bug. vr defined by an implicit_def is allowed overlap with any register since it doesn't actually modify anything. However, if it's used as a two-address use, its live range can be extended and it can be spilled. The spiller must take care not to emit a reload for the vn number that's defined by the implicit_def. This is both a correctness and performance issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69743 91177308-0d34-0410-b5e6-96231b3b80d8

in the MachineFunction class, renaming it to addLiveIn for consistency with the same method in MachineBasicBlock. Thanks for Anton for suggesting this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69615 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-19Remove the SimpleTy enumerated type field from the MVTDuncan Sands
value type union: this field was causing problems for some compilers on 64 bit systems, presumably because SimpleTy is 32 bits wide while the other fields are 64 bits wide. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69515 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18Don't try to make BUILD_VECTOR operands have the sameDuncan Sands
type as the vector element type: allow them to be of a wider integer type than the element type all the way through the system, and not just as far as LegalizeDAG. This should be safe because it used to be this way (the old type legalizer would produce such nodes), so backends should be able to handle it. In fact only targets which have legal vector types with an illegal promoted element type will ever see this (eg: <4 x i16> on ppc). This fixes a regression with the new type legalizer (vec_splat.ll). Also, treat SCALAR_TO_VECTOR the same as BUILD_VECTOR. After all, it is just a special case of BUILD_VECTOR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69467 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-13Change SelectionDAG type legalization to allow BUILD_VECTOR operands to beBob Wilson
promoted to legal types without changing the type of the vector. This is following a suggestion from Duncan (http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-February/019923.html). The transformation that used to be done during type legalization is now postponed to DAG legalization. This allows the BUILD_VECTORs to be optimized and potentially handled specially by target-specific code. It turns out that this is also consistent with an optimization done by the DAG combiner: a BUILD_VECTOR and INSERT_VECTOR_ELT may be combined by replacing one of the BUILD_VECTOR operands with the newly inserted element; but INSERT_VECTOR_ELT allows its scalar operand to be larger than the element type, with any extra high bits being implicitly truncated. The result is a BUILD_VECTOR where one of the operands has a type larger the the vector element type. Any code that operates on BUILD_VECTORs may now need to be aware of the potential type discrepancy between the vector element type and the BUILD_VECTOR operands. This patch updates all of the places that I could find to handle that case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68996 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Right now, Debugging information to encode scopes (DW_TAG_lexical_block) ↵Devang Patel
relies on DBG_LABEL. Unfortunately this intefers with the quality of optimized code. This patch updates dwarf writer to encode scoping information in DWARF only in FastISel mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68973 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-11Keep track of inlined functions and their locations. This information is ↵Devang Patel
collected when nested llvm.dbg.func.start intrinsics are seen. (Right now, inliner removes nested llvm.dbg.func.start intrinisics during inlining.) Create debug_inlined dwarf section using these information. This info is used by gdb, at least on Darwin, to enable better experience debugging inlined functions.

2009-04-09Fix pr3954. The register scavenger asserts for inline assembly withBob Wilson
register destinations that are tied to source operands. The TargetInstrDescr::findTiedToSrcOperand method silently fails for inline assembly. The existing MachineInstr::isRegReDefinedByTwoAddr was very close to doing what is needed, so this revision makes a few changes to that method and also renames it to isRegTiedToUseOperand (for consistency with the very similar isRegTiedToDefOperand and because it handles both two-address instructions and inline assembly with tied registers). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68714 91177308-0d34-0410-b5e6-96231b3b80d8
