2007-11-14Eliminate the recently introduced CCAssignToStackABISizeAlignDuncan Sands
in favour of teaching CCAssignToStack that size 0 and/or align 0 means to use the ABI values. This seems a neater solution. It is safe since no legal value type has size 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44107 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-14Added two new overloaded versions of BatchEmitOwnedPtrs andTed Kremenek
BatchReadOwnedPtrs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44105 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-14Clean up sub-register implementation by moving subReg information back toEvan Cheng
MachineOperand auxInfo. Previous clunky implementation uses an external map to track sub-register uses. That works because register allocator uses a new virtual register for each spilled use. With interval splitting (coming soon), we may have multiple uses of the same register some of which are of using different sub-registers from others. It's too fragile to constantly update the information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44104 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-14Allow the block extractor take to take a list of basic blocks to not extractNick Lewycky
from a file containing Function/BasicBlock pairings. This is not safe against anonymous or abnormally-named Funcs or BBs. Make bugpoint use this interface to pass the BBs list to the child bugpoint. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44101 91177308-0d34-0410-b5e6-96231b3b80d8

Kelly Wilson, thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44043 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-13Unify CALLSEQ_{START,END}. They take 4 parameters: the chain, two stackBill Wendling
adjustment fields, and an optional flag. If there is a "dynamic_stackalloc" in the code, make sure that it's bracketed by CALLSEQ_START and CALLSEQ_END. If not, then there is the potential for the stack to be changed while the stack's being used by another instruction (like a call). This can only result in tears... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44037 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-12Added versions of ReadPtr that takes an explicit SerializedPtrID. This allowsTed Kremenek
clients of the Deserializer to read the pointer ID before they are ready to deserialize the object (which can mean registering a pointer reference with the backpatcher). Changed some methods that took an argument "SerializedPtrID" to "const SerializedPtrID&" (pass-by-reference). This is to accommodate a future revision of SerializedPtrID where it may be much fatter than an unsigned integer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44021 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-11Use TableGen to emit information for dwarf register numbers. Anton Korobeynikov
This makes DwarfRegNum to accept list of numbers instead. Added three different "flavours", but only slightly tested on x86-32/linux. Please check another subtargets if possible, git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43997 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-10Fixed a bug introduced by my last patch. Now we properly clear out the ↵Ted Kremenek
BatchIDVec vector before reusing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43984 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-10Fixed hack in BatchReadOwnedPtrs to no longer use the array of pointers ↵Ted Kremenek
passed in for deserialization as a temporary location for storing serialized pointer identifiers. The definition of SerializedPtrID will likely change significantly in the future, and the current implementation caused compilation errors on some 64-bit machines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43983 91177308-0d34-0410-b5e6-96231b3b80d8
