similar to: [LLVMdev] loadable backend versus analysis pass

The test usage of this pass looks like this: void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.addRequired<MParSchedule>(); AU.setPreservesAll(); } and then in the

Hello, I have an analysis pass and a target machine class, both in different dynamically loadable libraries (plugins). There is no problem to use the analysis pass (opt -load=libanalysis.dylib -barpass foo.bc), but is it possible to get data from the analysis pass (by getAnalysis) while using the backend? AFAIK it is only allowed to have one plugin argument for llc (like: llc

Dear Nico, I believe you need to add LLVMipa to the list of libraries to link into your tool. FindUsedTypes::ID is defined in lib/Analysis/IPA. I think it would be LLVMipa.a if you added it to LLVMLIBS and ipa if you added it to LINK_COMPONENTS. -- John T.

Hello all, Is it well known that building LLVM with --enable-optimized causes RegisterPass calls to be removed from dynamically loadable libraries (i.e., those built with LOADABLE_MODULE=1)? For example, here's what happens to the Hello pass (ToT on Darwin, both with and without --enable-optimized): $ pwd /Users/ransford/llvm/lib/Transforms/Hello $ nm -j Release+Asserts/Hello.o | c++filt -p

Dear John, thanks! I was irritated by the path of the header file/declaration. It is not like the definition in a subdirectory. Sorry my fault. Is there an overview where classes and link options are mapped to each other?

Hi, I tried to implement an 'llc'-like tool in my project to manage different passes and a target machine. I use given llvm project structure to avoid problems but I have a link problem and don't know how to solve it: The target machine uses 'FindUsedTypes' pass and when I try to use my target machine in the tool I got "Undefined symbols:

Mmm, this code seems to kill polly: #include <stdio.h> #include <stdlib.h> int main() { char *B; int i,j,k,h; const int x = 0, y=0; B = (char *)malloc(sizeof(char)*1024*1024); for (i = 1; i < 1024; i++) for (j = 1; j < 1024; j++) { if (i+j > 1000) B[j] = i; } printf("Random Value: %d", B[rand() % 1024*1024]); return 0; } running: opt

Hi, I want to invoke the AddReadAttrs pass with my software backend (derived from TargetMachine like CBackend). CBackend uses addPassesToEmitWholeFile-method for invoking several passes. I tried to use the same method, but it failed on runtime. Running llc with my backend produces (mac os x 10.5 and llvm 2.4): dyld: lazy symbol binding failed: Symbol not found:

Hello, is there a method to access unnamed structure types? Maybe something similar to 'TypeSymbolTable'? 'CBackend' uses 'FindUsedTypes'-pass and a lot of glue code around it, but I don't want to use the 'Passmanager' etc. Thank you. Kind regards, Nico

Mmm I found out a very strange behavior (to me) of the SCEV analysis of the loop bound of the external loop I posted. When in ScopDetection it gets the SCEV of the external loop bound in the "isValidLoop()" function with: const SCEV *LoopCount = SE->getBackedgeTakenCount(L); It returns a SCEVCouldNotCompute, but if I change the "if" block inside the loop from: if

In trying to package up LLVM for Debian, it appears that x86_64 is no longer a supported architecture -- so, my first question is, is that correct? Best I can tell, the only thing that's supposed to work for x86_64 is the C backend. For Debian, I need to build everything from scratch. When trying to build llvm-gcc4 from source, though, I get part way through the build and am told that

Yep, it sounds like a good solution, and it works for me - thanks! -mike On Mon, 10 Jan 2005 20:40:34 -0800, Reid Spencer <reid at x10sys.com> wrote: > Michael, > > I've implemented a LOADABLE_MODULE feature in the makefiles: > > http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050110/023147.html > > The approach taken is almost what you described

Michael, I've implemented a LOADABLE_MODULE feature in the makefiles: http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050110/023147.html The approach taken is almost what you described below. However, I want to retain the distinction between a "regular" shared library and one that can be dlopened. So, if you specify SHARED_LIBRARY=1 you get a regular shared library

Hi, a while back I wrote that the llvm makefiles didn't create the correct kind of file for use on darwin with -load. Since then, both the shared library and makefile system have been overhauled significantly. So I checked again - as updated from CVS, the current makefiles don't build the right object type on darwin. If you follow the advice of 'Writing an LLVM Pass" tutorial,

Thanks, Also, every method inherited by LoopBase causes the same error, while Loop methods go smooth.
