..."barrier()" function, as well as various target specific memory fence intrinsics, should prevent loads/stores of the relevant address space from being moved across them. Kernel pointers with "restrict" attributes are implemented by marking the pointer "noalias" in the LLVMIR. However, in LLVM, "noalias" pointers are not affected by llvm memory fence instructions. To make sure all loads/stores, including those accessing "restrict" pointers are not moved across the barrier/fence intrinsics, we have considered using customized alias analysis passes. H...

Hi Eric, I'm currently writing an IA-32 to LLVMIR translator. I'm only mid way through, but I can certainly say that there have been more difficulties than I anticipated when I began! I think that it is a reasonable approach, perhaps especially in your case, since you have an emulator already. Automatic static translation is equivalent to the...

First, is there a way to search the archives for this list ? I apologize in advance if I have stepped on a FAQ. My goal is to execute legacy binary machine code from a very old one of a kind computer on a variety of modern computers. I already wrote an emulator for the legacy machine that executes the old machine code. However, my emulator is just an interpreter and therefore has

...but, one word of caution, even bb2 and bb3 can be preceeded by some other basic blocks, thus the count for bb5 (number of predecessors) won't be 2, but would be more (depends upon the predecessors of bb2 and bb3). You can also try to utilize the branching info at the end of each basic block in llvmIR of the source. I am working on something similar, do let me know if u need some specific information.

(-1 karma to self for participating in bikeshed) I'm not sure how and if this change would affect my group, but I'd have a slight preference to llvm/lib/LLVMIR/ ----------- While the current naming may not be the best I'm -1 for the change in general.

Enables other frontends (e.g. f18) to add scalar-to-vector function mappings as relevant for their own runtime libraries, etc. The implemetation consists of two separate sets of changes. The first set is a set o changes in `llvm`, and consists of: 1. [Changes in LLVM IR](#llvmIR) to provide information about the availability of user-defined vector functions via metadata attached to an `llvm::CallInst`. 2. [An infrastructure](#infrastructure) that can be queried to retrive information about the available vector functions associated to a `llvm::CallInst`. 3....
