2010-07-06Convert INSERT_SUBREG to COPY in TwoAddressInstructionPass.Jakob Stoklund Olesen
INSERT_SUBREG will now only appear in SSA machine instructions. Fix the handling of partial redefs in ProcessImplicitDefs. This is now relevant since partial redef COPY instructions appear. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107726 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-06Be more forgiving when calculating alias interference for physreg coalescing.Jakob Stoklund Olesen
It is OK for an alias live range to overlap if there is a copy to or from the physical register. CoalescerPair can work out if the copy is coalescable independently of the alias. This means that we can join with the actual destination interval instead of using the getOrigDstReg() hack. It is no longer necessary to merge clobber ranges into subregisters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107695 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-06Fix a major regression on COFF targets introduced by r103267: 'discardable' ↵Anton Korobeynikov
section means that it is used only during the program load and can be discarded afterwards. This way *only* debug sections can be discarded, but not the opposite. Seems like the copy-and-pasto from ELF code, since there it contains the reverse flag ('alloc'). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107658 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-02Add a new target independent COPY instruction and code to lower it.Jakob Stoklund Olesen
The COPY instruction is intended to replace the target specific copy instructions for virtual registers as well as the EXTRACT_SUBREG and INSERT_SUBREG instructions in MachineFunctions. It won't we used in a selection DAG. COPY is lowered to native register copies by LowerSubregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107529 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-02Custom inserters (e.g., conditional moves in Thumb1 can introduceJim Grosbach
new basic blocks, and if used as a function argument, that can cause call frame setup / destroy pairs to be split across a basic block boundary. That prevents us from doing a simple assertion to check that the pairs match and alloc/ dealloc the same amount of space. Modify the assertion to only check the amount allocated when there are matching pairs in the same basic block. rdar://8022442 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107517 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-02- Two-address pass should not assume unfolding is always successful.Evan Cheng
- X86 unfolding should check if the instructions being unfolded has memoperands. If there is no memoperands, then it must assume conservative alignment. If this would introduce an expensive sse unaligned load / store, then unfoldMemoryOperand etc. should not unfold the instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107509 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-02Propagate the AlignStack bit in InlineAsm's to the Dale Johannesen
PrologEpilog code, and use it to determine whether the asm forces stack alignment or not. gcc consistently does not do this for GCC-style asms; Apple gcc inconsistently sometimes does it for asm blocks. There is no convenient place to put a bit in either the SDNode or the MachineInstr form, so I've added an extra operand to each; unlovely, but it does allow for expansion for more bits, should we need it. PR 5125. Some existing testcases are affected. The operand lists of the SDNode and MachineInstr forms are indexed with awesome mnemonics, like "2"; I may fix this someday, but not now. I'm not making it any worse. If anyone is inspired I think you can find all the right places from this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107506 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-02Rematerialize as much as possible before inserting spills and reloads.Jakob Stoklund Olesen
This allows us to recognize the common case where all uses could be rematerialized, and no stack slot allocation is necessary. If some values could be fully rematerialized, remove them from the live range before allocating a stack slot for the rest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107492 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
