...lvm-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 with the example codes of CellSDK. Is there any alternate way / intrinsic which can be called to introduce calls to the Cell C intrinsic functions??

...the loop. A second alternative could be I run a module pass and go through the loop inside that. Is there a way to call the loop pass from inside the module pass or obtain information about the loops present inside the module and individually call the loop pass on them.

.... From what I know it is not allowed to modify anything outside the loop's scope in a loop pass. A runonFunction method will run on functions and probably able to add this new struct type to the module. Can you provide me pointers towards obtaining loops inside runOnFunction method?

...(); AU.addPreserved<LoopInfo> (); } I picked this from the LPPassManager class which has a similar structure and its runOnFunction iterates over loop list from LoopInfo. I think I am missing some line to add. Can someone please point out the cause of the error??

...e header files by a transformation pass and able to use the types defined in the header file in the pass itself. A similar scenario can arise in a parallelizing transformation where one is trying to create threads but this requires inclusion of pthread.h to access the types like pthread_t. etc. -- Kshitiz Garg Graduate Student Department of Computer Science & Engineering IIT Kanpur -------------- next part -------------- An HTML attachment was scrubbed...
