Andrew Trick 501aeea325 StackMap: Implement support for DirectMemRefOp. ... A Direct stack map location records the address of frame index. This address is itself the value that the runtime requested. This differs from IndirectMemRefOp locations, which refer to a stack locations from which the requested values must be loaded. Direct locations can directly communicate the address if an alloca, while IndirectMemRefOp handle register spills. For example: entry: %a = alloca i64... llvm.experimental.stackmap(i32 <ID>, i32 <shadowBytes>, i64* %a) Since both the alloca and stackmap intrinsic are in the entry block, and the intrinsic takes the address of the alloca, the runtime can assume that LLVM will not substitute alloca with any intervening value. This must be verified by the runtime by checking that the stack map's location is a Direct location type. The runtime can then determine the alloca's relative location on the stack immediately after compilation, or at any time thereafter. This differs from Register and Indirect locations, because the runtime can only read the values in those locations when execution reaches the instruction address of the stack map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195712 91177308-0d34-0410-b5e6-96231b3b80d8		2013-11-26 02:03:25 +00:00
