I am using opt , so i cm confused if i need to do this. On the other hand I modified my functionPass not to call TargetData , and I still get this error. My functionPass still calls Alias Analysis though.

All, I have a ModulePass (A) calling a FunctionPass that inturn calls TargetData (a ModulePass). For reasons of code correctness and modularity I cannot reorganize my passes in any other way . When I use opt to load and run A , it gives the following error. LLVM ERROR: Bad TargetData ctor used. Tool did not specify a TargetData to use? I gather from some previous emails that this was not

Hi Sebastian, Sure! The bulk of LMDA was written by Aparna Kotha (CCd). It computes dependences between all instructions, computes the resulting direction vectors in the function, then associates them all with loops. At a high level, the dependence analysis consults with AliasAnalysis, and ScalarEvolution before resorting to attempting to understand the effective affine expressions and

I am using pthreads. I was also wondering what will the llvm IR be for pthreads ?

I believe because cygwin behaves like windows (it is just a posix layer over window) it doesn't have dynamic linking hence only static libraries have been built.

Thanks a lot. A see the shared library in linux version. I initially tried doing this in cygwin where I dont see the shared library being built. Do u think it could have been cygwin that is the problem?

Luke gave hints on how to get pthreads to work. LLVM doesn't do anything special for pthreads calls. So they should look like regular calls into a library. -bw

Hi all: I need an instruction that can convert decimal values into floating point numbers. i.e. say I have a decimal number 1110794174 (== 42355FBE in hex ) and (== 45.3435 as a float) essentially the mantissa and exponent representation needs to be used. Is there any way of doing this in llvm? Thanks and Regards -- -- Aparna Kotha Graduate Student Electrical and Computer Engineering

In order to generate shared libraries you need to have SHARED_LIBRARY and LOADABLE_MODULE defined in the Makefile. See here for more details: http://llvm.org/docs/MakefileGuide.html#libraries On 13 Apr 2009, at 20:46, aparna kotha wrote: > I am trying to run the LLVM hello world pass.

I am trying to run the LLVM hello world pass. I observe that in the OUPUT_DIR/lib the LLVMHello.a and LLVMHello.la libraries are generated. But I am confused as to how to generate the .so library file from here. I am kinda new to compilers and hence the question I know is basic , but couldnt figure the answer out myself. Thanks a lot for your help. Regards -- -- Aparna Kotha Research

Right. But there are 8 registers on the floating point stack from ST0 to ST7 and I think llvm is only using ST0 to ST6 in some code fragments. Could this be because of the assumption that X86::FP registers run from X86::FP0 to X86:FP6 ? --Aparna On Wed, May 25, 2011 at 2:28 PM, Jakob Stoklund Olesen <stoklund at 2pi.dk>wrote: > > On May 25, 2011, at 11:09 AM, aparna kotha wrote:

Hi Guys, I was working on some floating point intensive benchmarks and realize that the floating point register allocation in llvm assumes that there are only 7 floating point registers in X86, whereas the hardware has 8. Line number 00266 assert(Reg >= X86::FP0 && Reg <= X86::FP6 && "Expected FP register!"); of X86FloatingPoint.cpp. Is there any reason for

Hi all: I am working on a project using llvm and we need to deal with multithreaded applications. I wanted to know if there was a C front end for llvm that could parse multithreaded applications? I tried llvm-gcc (4.2) and could not get it to work. Is there an extra parameter that I need to pass or something ? Thanks a lot for your help. Regards -- -- Aparna Graduate Student Department

All: I am looking at a optimization which requires me to lower the getelementptr instruction in llvm. Is there a way to do this in llvm or do i have to write a new pass for this?
