I am just not upgrade my LLVM.

...ruction, right? However, I think value "i32* getelementptr inbounds (%struct.Args* @globalArg, i64 0, i32 2)" itself is not a getelementptr instruction, so? Or could you tell me how can I get a getelementptr instruction first from this value? -------------------------------------------- Qiuping Yi Institute Of Software Chinese Academy of Sciences On Sat, Nov 22, 2014 at 4:49 PM, Michael Zolotukhin <mzolotukhin at apple.com> wrote: > Hi Qiuping, > > I guess you need to use getPointerOperand to access the pointer operand > (@globalArg in your example) and idx_begin/idx_e...

Which compiler are you using to compile poolalloc? Looks like it doesn't support C++11 (doesn't recognize nullptr).

Thank you.

For working with poolalloc, I would recommend using LLVM 3.2 as we know poolalloc compiles with LLVM 3.2. If there's a release_29 branch for poolalloc, you could use that, but you won'...

Dear Qiuping, If you use the release_32 branch of poolalloc, then you need to use LLVM 3.2. For directions on compiling poolalloc with LLVM 3.2, please the SAFECode build directions at http://safecode.cs.illinois.edu/docs/Install.html. You can just skip the steps in the directions that compile SAFECode....

...ible to directly catch the fact that the load of x at the statement 'data1 = x; ' dependents on data4 (because of the statement x=data4 )? If I want to get such information, may be the only solution is to traverse all the predecessors of the statement 'data1 = x;'.

...ody of 'myStore'. However, when I use 'myLoad' to return the stored value to '%0', the 64bits value is truncated to a 32bits value. For example, '140583176769504' is returned in 'myLoad', but actually '306205760' is assigned to %0.
