similar to: [LLVMdev] Errors in Documentation

Hi all, I am testing link time optimizations with clang on linux x86_64 machine running Ubuntu Maverick. I am using clang with llvm release-3.0 I followed the instructions on http://llvm.org/docs/LinkTimeOptimization.html However, when I try to compile with one file being bitcode and other being native code exactly as shown in the documentation, I get the following errors clang a.o main.o -o

LLVM developers, I was wondering if the program would still be safe if I strip the byval attributes from the parameters in the entire bitcode. LLVM language reference manual states that "The attribute implies that a hidden copy of the pointee is made between the caller and the callee, so the callee is unable to modify the value in the callee. This attribute is only valid on LLVM pointer

These are primarily due to deferences to external globals arrays in the module. These arrays are probably defined elsewhere and linked together later.

Hi all, I am trying to change the prototype of all functions in the bitcode. Specifically I want to add an extra argument to all functions definitions and call sites. What is the best way to accomplish this using the LLVM API? Currently I accomplish this by using a module pass which iterates over all the functions in the module. For each function, I create a new function with an extra

Hi all, I have been trying to understand the use of undef in both sequential and concurrent programs. >From the LLVM Language Reference Manual, I see the following definition of undef. "Undef can be used anywhere a constant is expected, and indicates that the user of the value may receive an unspecified bit-pattern". LLVM Language Reference manual also demonstrates how optimizers

Hi, Can you add the following two publications from our group to the LLVM publications page. - *Alive-FP: Automated Verification of Floating Point Based Peephole Optimizations in LLVM [pdf] <http://www.cs.rutgers.edu/~santosh.nagarakatte/papers/alive-fp-sas16.pdf> *David Menendez, Santosh Nagarakatte, and Aarti Gupta *To Appear in the Proceedings of the 23rd Static Analysis

Hello, As far as I know, there is no MPX pass in LLVM (though the x86-64 backend already declares MPX registers and instructions). I wonder if anyone is currently working on the LLVM pass for MPX instrumentation, similar to Pointer Checker in gcc. If yes, could anyone elaborate on the status and accessability to other researchers? And if any help is needed? Prof. Santosh Nagarakatte, the author

I'm still in need for moderators for the following sessions: > Moderator #3 (11:15-12:45, Regency 1) > Verified LLVM: Formalizing the semantics of the LLVM Intermediate Representation for Verified Program Transformations- Santosh Nagarakatte, University of Pennsylvania/Rutgers University > Integrated Security, using LLVM for Dynamic and Static Security Tasks- Jared Carlson,

LLVM developers, Can you add the following paper to the publication list? "Formal Verification of SSA Optimizations for LLVM" Jianzhou Zhao, Santosh Nagarakatte, Milo M K Martin and Steve Zdancewic Proceedings of the 34th ACM SIGPLAN Conference on Programming Language Design and Implementation (PLDI) 2013 link to ACM DL:

Hello, I am in need of moderators to help moderate each session. If you are interested, please respond to this mail and indicate which slot you can moderate. Its a long shot as you would miss talks, but if anyone wants a break to do work or check email while also staffing the registration desk, please let me know if you can do it during any of the sessions below. Thanks! Options: Moderator #1
