lmGlobalRegArg :: Platform -> GlobalReg -> LlvmVar

Get the LlvmVar function argument storing the real register

lmGlobalRegVar :: Platform -> GlobalReg -> LlvmVar

stgTBAA :: [(Unique, LMString, Maybe Unique)]

STG Type Based Alias Analysis hierarchy

baseN :: Unique

Id values The rootN node is the root (there can be more than one) of the TBAA hierarchy and as of LLVM 4.0 should *only* be referenced by other nodes. It should never occur in any LLVM instruction statement.

stackN :: Unique

Id values The rootN node is the root (there can be more than one) of the TBAA hierarchy and as of LLVM 4.0 should *only* be referenced by other nodes. It should never occur in any LLVM instruction statement.

heapN :: Unique

Id values The rootN node is the root (there can be more than one) of the TBAA hierarchy and as of LLVM 4.0 should *only* be referenced by other nodes. It should never occur in any LLVM instruction statement.

rxN :: Unique

Id values The rootN node is the root (there can be more than one) of the TBAA hierarchy and as of LLVM 4.0 should *only* be referenced by other nodes. It should never occur in any LLVM instruction statement.

topN :: Unique

Id values The rootN node is the root (there can be more than one) of the TBAA hierarchy and as of LLVM 4.0 should *only* be referenced by other nodes. It should never occur in any LLVM instruction statement.

tbaa :: LMString

The TBAA metadata identifier

getTBAA :: GlobalReg -> Unique
