similar to: [LLVMdev] Codegen error with instrinsic

Hello, I was trying to extract out the IR for some CELLBE code. However i was not able to compile with llvm-gcc. Has someone who has tried this shed some light on the changes required to use llvm-gcc instead of gcc or xlc. A simple replacement of gcc with llvm-gcc -emit-llvm -S or marking $CC as llvm-gcc in the makefile did not work for me. I am using the standard makefile format supplied

I am trying to use the indvars pass on a simple loop but it does not seem to have any effect The sample code i am using is #include <stdio.h> int test (int p); int main(){ int a,b=3; for(a=7;a*a<100;++a){ if(b >3) test(3); b++; } return 1; } int test(int p){ return p; } According to documentation

Devang, Let me reframe my question.I require to keep this extra information as a structure so as to pass it around to other functions which require it. Specifically I am working on CellBE and wish to DMA this information to the SPEs The way of adding the information by PHI nodes will not suffise since the information may be very large in some cases which will need to be transfered by a DMA rather

Hello, I wanted to do some speculative execution on a loop for which I require some data storage structure for book keeping. The exact structure of this storage buffer can only be determined after loop analysis. Is there a clean way to add this new structure to the module. Since this structure is to be used for each loop iteration I do not want to allocate it inside the loop. A second

Hello, I was trying to get the loop info in a module pass to be able to iterate over the loops int the module itself. Since my pass requires to make module level changes including adding new types to module hence a looppass cannot be used here. I am getting the following error on running opt. opt: /root/llvm-2.4/include/llvm/PassAnalysisSupport.h:199: AnalysisType&

Hello, Is there a way such that one can insert #pragmas and /or comments in the IR such that the C code produced by llc has those pragmas which can be used later by another tool?. Say for example I have a pass that shall do some analysis and modifications to provided source code. Then I wish to parallelize the modified loop using open-MP by inserting openmp pragmas in the generated c

Dear list, I am facing a problem in my statistical analyses on R. My experiments are about plants, I record there growth after each cutting (every 3 weeks). 'BC' is for the plant, and '1' to '5' is the time of cutting and recording. The data and R script are : "" BourdCoup <- c(21, 7.2, 9.2, 0, 8.52, 14.7, 8.31, 6.2, 127.05, 115.2, 100.7, 24, 162.64, 136.8,

This is a little off topic, but maybe someone can help. I have a Win2K laptop that's part of a corporate domain. When I bring it home and add it to my home LAN, it refuses to access any SMB machine (including a Samba server, Win98 or Win95 box) complaining that "There are currently no logon servers available to service the logon request." Is there any way to fix this easily? I
