similar to: [LLVMdev] AliasAnalysis calling failed in Pass interaction

Folks, I''m trying to figure out whether we should give ZFS / mpxio a shot on one of our research servers, or simply skip it (as we have previously). In Nov 2009 Cindy responded to a thread concerning ZFS device issues, cfgadm, and mpxio: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-November/033496.html I''ve got an x2270 with the Sun EZ-SAS HBA and external SATA

Hi all, i hope to get the MemoryLocation for argument %1 in a CallInst like "call void @function(i32* %1)", and i found an interface "getForArgument()" which seems available for this. However, i don't know how to correcly fill the 3rd argument TargetLibraryInfo in my own code and can't find an example in google. Does anybody know how to do it? Or some other advice for

CentOS 5.6 x64 installs successfully on HP 6200pro SFF box with Intel Q65X Express chipset (including HD graphics), Core i5 and added NVS300 graphics card. Actually, it works great. HP lists "RedHat Enterprise x64" as a supported OS. The 6200pro is a "business desktop" that became available in early summer 2011. CentOS 6.2 x64 install halts during initial boot, with boot

Dear All, To add to this, you can find examples of inserting NOPs for X86 in the CFI pass originally written at Lehigh University that we ported to 64-bit X86 for SVA: https://github.com/jtcriswell/SVA/blob/master/llvm/lib/Target/X86/X86CFIOptPass.cpp Alternatively, you could use an InlineAsm call at the LLVM IR level (which I think would be easier to implement).

Dear LLVM developers, My name is Ben Niu and I am a Ph.D. student at Lehigh University. I compiled the MUSL C library using Clang 3.3, and dumped the generated LLVM IR files. I found that the MUSL-defined FILE struct (aliasing __FILE_s) struct __FILE_s { unsigned flags; unsigned char *rpos, *rend; int (*close)(FILE *); unsigned char *wend, *wpos; unsigned char *mustbezero_1;

Hi all, I plan to use LLVM to instrument/rewrite X86 instructions during the compilation of a program. For example, insert checking target instructions before jmp instructions, or rewrite a instruction to prevent code using a specific register. I think the work should be done at the CodeGen phase, but I'm not quite clear how can I start. Can anyone give me some suggestion? Thanks very much,

John, thanks for your helpful advice. My ultimate goal is to construct a full instruction-level program dependence graph for a given IR file. The hard point is how to establish the correct data dependence edges when some function arguments are multi-level pointers. To solve this problem I hope to check the point-to level for each pointer variable. I think the data dependence through pointers can

Hello, I plan to implement "Stack Smashing Protection - Strong" support in LLVM. Below is a description of this feature and an overview of the implementation plan. I have divided up the implementation into stages that can be delivered incrementally. I'm looking for any feedback (suggestions, requests, etc) before I actually begin the work. Thank you! Josh

Hi, RFC Im adding 2 new functions to the AliasAnalysis interface: 1) ModRefSameBufferCheck: this function will receive 2 memoryLocation as parameters, and returns true if the parameters are modifying or refering the same buffer or same memory block, false otherwise. 2) getAddressesDistance: the function will recieve 2 memoryLocation, if they are mod/ref-ing the same buffer/memory block, the

Hi, The description of the alias method in AliasAnalysis reads: alias - The main low level interface to the alias analysis implementation. Returns a Result indicating whether the two pointers are aliased to each other. This is the interface that must be implemented by specific alias analysis implementations. This implies that alias can run on ANY two Values without restrictions. However, line

What do you think of this patch? I have added a check for the case I mentioned in the previous email as well as a similar situation I discovered later.

Hi All, I'm trying to use the inbuilt AliasAnalysis function for one of my projects. Im trying to find out if a pair of load and store alias each other. It would be helpful if somebody could point out the right way to do this. Example : %13 = load i32* %12, align 4 store i32 30, i32* %4, align 4 So in the above example i'm trying to find out if
