2006-06-161. Revise vector debug support.Jim Laskey
2. Update docs for vector debug support and new version control. 3. Simplify serialization of DebugDescInfo subclasses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28816 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-15Teach the local allocator to know that live-in values (e.g. arguments) areChris Lattner
live at function entry. This prevents it from using arg registers for other purposes before the arguments are used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28809 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-151. Support standard dwarf format (was bootstrapping in Apple format.)Jim Laskey
2. Add vector support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28807 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-15Was pointed out that structure alignment and type alignment are not the sameJim Laskey
thing. Doubles still need to be special cased. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28806 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-15Alignment of globals has not been quite right. Needed to drop the pointer typeJim Laskey
to get the alignment of the element type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28799 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-15Consistency. EXTRACT_ELEMENT index operand should have ptr type.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28795 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-15Assert. Rather than silently stop printing.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28794 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-15Instructions with variable operands (variable_ops) can have a number requiredEvan Cheng
operands. e.g. def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops), "call {*}$dst", [(X86call GR32:$dst)]>; TableGen should emit operand informations for the "required" operands. Added a target instruction info flag M_VARIABLE_OPS to indicate the target instruction may have more operands in addition to the minimum required operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28791 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-14Change versioning to per debug info descriptor (merged with tag.)Jim Laskey
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28782 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-14Place dwarf headers at earliest possible point. Well behaved when skippingJim Laskey
functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28781 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-13Port some bugfixes in shift handling from SimplifyDemandedBits over toChris Lattner
ComputeMaskedBits. DemandedMasks and KnownZero/One masks should never have bits set out of the range of the base datatype. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28768 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-13TargetLowering::ComputeMaskedBits was not clearing reciprocal bits on shifts.Jim Laskey
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28765 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-01Use archive libraries instead of object files for VMCore, BCReader,Reid Spencer
BCWriter, and bzip2 libraries. Adjust the various makefiles to accommodate these changes. This was done to speed up link times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28610 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-30Make sure the register pressure reduction schedulers work for non-uniformEvan Cheng
latency targets, e.g. PPC32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28561 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-30When a priority_queue is empty, the behavior of top() operator isEvan Cheng
non-deterministic. Returns NULL when it's empty! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28560 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-27Fix a nasty dag combiner bug that caused nondeterminstic crashes (MY FAVORITE!):Chris Lattner
SimplifySelectOps would eliminate a Select, delete it, then return true. The clients would see that it did something and return null. The top level would see a null return, and decide that nothing happened, proceeding to process the node in other ways: boom. The fix is simple: clients of SimplifySelectOps should return the select node itself. In order to catch really obnoxious boogs like this in the future, add an assert that nodes are not deleted. We do this by checking for a sentry node type that the SDNode dtor sets when a node is destroyed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28514 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-26Make CALL node consistent with RET node. Signness of value has type MVT::i32Evan Cheng
instead of MVT::i1. Either is fine except MVT::i32 is probably a legal type for most (if not all) platforms while MVT::i1 is not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28511 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-26Change RET node to include signness information of the return values. e.g.Evan Cheng

2006-05-17Fix the result of the call to use a correct vbitconvert. There is no need toChris Lattner
use getPackedTypeBreakdown at all here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28365 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-17Fixed a LowerCallTo and LowerArguments bug. They were introducing illegalEvan Cheng
VBIT_VECTOR nodes. There were some confusion about the semantics of getPackedTypeBreakdown(). e.g. for <4 x f32> it returns 1 and v4f32, not 4, and f32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28352 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-17Fix an obvious bug in getPackedTypeBreakdown. Return 1 if type is legal.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28351 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-17When we legalize target nodes, do not use getNode to create a new node,Chris Lattner
use UpdateNodeOperands to just update the operands! This is important because getNode will allocate a new node if the node returns a flag and this breaks assumptions in the legalizer that you can legalize some things multiple times and get exactly the same results. This latent bug was exposed by my ppc patch last night, and this fixes gsm/toast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28348 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-16Add a chain to FORMAL_ARGUMENTS. This is a minimal port of the X86 backend,Chris Lattner
it doesn't currently use/maintain the chain properly. Also, make the X86ISelLowering.cpp file 80-col clean. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28320 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-16Move function-live-in-handling code from the sdisel code to the scheduler.Chris Lattner
This code should be emitted after legalize, so it can't be in sdisel. Note that the EmitFunctionEntryCode hook should be updated to operate on the DAG. The X86 backend is the only one currently using this hook. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28315 91177308-0d34-0410-b5e6-96231b3b80d8
