Hi Rinaldini, In order to find information about loops inside a given function you should use something like "LoopInfo *LI = P->getAnalysis<LoopInfo>()", remembering to add "AU.addRequired<LoopInfo>();" to your getAnalysisUsage method. If the function you are interested to...

Rinaldini, What exactly did you run? Specifically, you may be missing some analysis passes that are necessary for LoopInfo to have the loop information you desire. -Hal On Thu, 26 Apr 2012 14:02:04 +0000 Rinaldini Julien <julien.rinaldini at heig-vd.ch> wrote: > Hi, > > I'm trying to...

Hi, I'm trying to detect if a basicblock is part of a loop or not. I tried the llvm::LoopInfo like that (http://llvm.org/docs/doxygen/html/classllvm_1_1LoopInfo.html#a4abca289c73cd09487e05d11d9f7d877): LoopInfo *loop = new LoopInfo(); bool isLoop = loop->getLoopFor(myBB); // getLoopFor - Return the inner most loop that BB lives in. If a basic block is in no loop (for example the entry

Hi, I have a question about the llvm passes. I'm iterating over a basicblock and I can get an instruction and print it. Now, I want to iterate over the instruction and be able to modify the values of the instruction. For example, if my instruction is an add "<result> = add i32 4, %var" I want to transform it in a sub "<result> = sub i32 4, %var". I looked up

Hi Rinaldini, You probably need to illustrate what your enviroment is, what revision you checkout and how you build LLVM. I have no problem build LLVM svn here.

Thx for your answer... Why would it define it again? I just want to use this register and add something to it... Cheers

Hi, I'm writing a pass that implements a jump table with an array of blockaddress and an indirectbr instruction. It get a blockaddress in the array (via getelementptr and an index) and then jump to this basicblock via the indirectbr. I tried to compile several libraries to test my pass and the run their test-suite. It works fine with, for e.g, libTomCrypt (in -O0,1,2,3). With GMP or

Hi, I want to *tag* some functions with some *flags*. I was using annotate((“myFlag”)) and everything was working fine until I tried on ObjC method. It seems that clang just ignore it. So, to be able to *flag* my functions I’m trying to add a *real* attribute to clang. I’ve added a new attribute to clang in tools/clang/include/clang/Basic/Attr.td: def NoFLA : Attr { let Spellings =

...t; is a single ctrl-M character. The ^M is seen by the asm parser as an end-of-line, so the '18' is a new token at the start of a line, not part of the comment. Is your pass perhaps using label names which might include literal "^M" characters? -Jim On Jun 13, 2012, at 5:51 AM, Rinaldini Julien <julien.rinaldini at heig-vd.ch> wrote: > Hi, > > I'm having some problem with llvm-mc on a program after applying a pass: > > ../../../build/Release+Asserts/bin/clang -emit-llvm -c -I./testprof/ -I./src/headers/ -I../libtommath-0.42.0/ -Wall -Wsign-compare -W -W...

...y using the libgmp and OpenSSL libraries test suites. I know that clang is *not* relying on the va_arg intrinsic, but implements itself this set of function, hence my question: is the va_arg intrinsic something we can trust to work with, or not?
