...lloc ... Regression tests are also completed for this pass. This week, I plan to 1. Test SAFECode’s bbac implementation on more real-world programs, and fix possible crashes. 2. Discuss with my mentor Prof. John Criswell about the insertion point of free in PromoteArrayAllocas pass.

....used will cause a fail because only users of direct call/invokes are allowed on intrinsic functions. Fortunately, after some discussion with my GSoC mentor, Prof. Criswell, we chose to rewrite the pass to a module pass, this solves this issue perfectly. Thanks for your patience.

...hoice for the scheme frontend of LLVM. On the other hand, compile scheme to LLVM IR will make use of LLVM's optimization techniques. The LLVM backend will boost the performance of bigloo. In this summer, I would like to build a robust, high-performance scheme frontend for LLVM.

...of direct call/invokes are allowed for intrinsic functions. So is it impossible to solve this problem by inserting intrinsic function prototype? Could you please give me some ideas on this , to make these intrinsic functions prototypes survive from llvm optimizations? Thank you. Best regards, Zhengyang.

Hi Zhengyang, Do you mind sharing _why_ you need the intrinsic declarations to stay around? It is possible that there is a better way of solving your problem. Thanks! -- Sanjoy

Hi, This is a follow up on a discussion around shufflevector with undef mask in https://reviews.llvm.org/D70641 and https://bugs.llvm.org/show_bug.cgi?id=43958. The current semantics of shufflevector in http://llvm.org/docs/LangRef.html#shufflevector-instruction states: "If the shuffle mask is undef, the result vector is undef. If any element of the mask operand is undef, that element

Dear Josh, > If I understand correctly, if you find memory leak, you want to find the corresponding call(s) to malloc() that allocated the memory object, correct? Can you more completely explain what you are trying to accomplish? Thanks for your reply. In my task, I use data flow analysis to locate a program point where a malloc must be leaked (by must leaked, I mean (a) it must be

Hello all, This is a proposal for reducing # of ptrtoint/inttoptr casts which are not written by programmers but rather generated by LLVM passes. Currently the majority of ptrtoint/inttoptr casts are generated by LLVM; when compiling SPEC 2017 with LLVM r348082 (Dec 2 2018) with -O3, the output IR contains 22,771 inttoptr instructions. However, when compiling it with -O0, there are only 1048
