2010-11-14move all the target's asmprinters into the main target. The piece Chris Lattner
that should be split out is the InstPrinter (if a target is mc'ized). This change makes all the targets be consistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119056 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Inside the calling convention logic LocVT is always a simpleDuncan Sands
value type, so there is no point in passing it around using an EVT. Use the simpler MVT everywhere. Rather than trying to propagate this information maximally in all the code that using the calling convention stuff, I chose to do a mainly low impact change instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118167 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-21fix a long standing wart: all the ComplexPattern's were beingChris Lattner
passed the root of the match, even though only a few patterns actually needed this (one in X86, several in ARM [which should be refactored anyway], and some in CellSPU that I don't feel like detangling). Instead of requiring all ComplexPatterns to take the dead root, have targets opt into getting the root by putting SDNPWantRoot on the ComplexPattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114471 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-21reimplement memcpy/memmove/memset lowering to use MachinePointerInfoChris Lattner
instead of srcvalue/offset pairs. This corrects SV info for mem operations whose size is > 32-bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114401 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12CMake: Fix MSVS build. Although I don't know why this didn't break other ↵Michael J. Spencer
build systems... This problem is unrelated to the recent dependency tracking change. It seems like noone noticed the problem because I don't think anyone compiles any target other than X86 on windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113727 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-07Add X86FastISel support for return statements. This entails refactoringDan Gohman
a bunch of stuff, to allow the target-independent calling convention logic to be employed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107800 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-01Implement the "linker_private_weak" linkage type. This will be used forBill Wendling
Objective-C metadata types which should be marked as "weak", but which the linker will remove upon final linkage. However, this linkage isn't specific to Objective-C. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". Currently only supported on Darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107433 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-17Add a DebugLoc parameter to TargetInstrInfo::InsertBranch(). ThisStuart Hastings
addresses a longstanding deficiency noted in many FIXMEs scattered across all the targets.
