False Alarm!! Still don't know how to do it! I am trying to write a transformation pass to extract a loop body into a function. For example: The Loop in question is: for (i2 = 0; i2 < LOOP_SIZE; i2++) { A[B[i2]] = 2 * B[i2]; } The IR for which is: bb13: ; preds = %bb13, %bb %i2.0.reg2mem.0 = phi i32 [ 0, %bb ], [ %indvar.next62, %bb13 ] ; <i32>

no .. i am calling a function pass from a module pass, adding other function passes to my module pass works, but when i try to add MemoryDependenceAnalysis it gives error I want to report a bug but i don't know if this is a real bug or i am doing something wrong, knowing that i am adding other function passe to my module pass and it works fine. the error i get: adding callgraph pass ...

actually i only created a new Module pass and tried to getAnalysis of MemoryDependenceAnalysis from it, i didn't use TargetData directly to regenerate the error i am attaching a c file containing an example code to regenerate the error. with its Makefile the command line i used is: opt -time-passes -analyze -load ${LLVM_PATH}/Release/lib/.libs/libMYMODULEPASS.so -MyModulePass < test.bc

Dear all, I am having a problem adding a MemoryDependenceAnalysis pass to a Module Pass i created, it gives me the following error when i add (Info.addRequired<MemoryDependenceAnalysis>();) it in the getAnalysisUsage(AnalysisUsage &Info) function. adding callgraph pass ... done opt: /net/home/yehia/llvm/llvm-2.4/include/llvm/Target/TargetData.h:114:

Hi All, I am having trouble extracting loop body into a new function. The ExtractLoop() or ExtractBasicBlock() extracts the entire loop along with the header into a new function. All I want is to extract the body of the loop into a new function(without the header). Is this possible? Thanks, Mrunal

I have a transformation where I'd like to use both DominatorTree (for ExtractCodeRegion), and DemoteRegisterToMemory (i.e., reg2mem). The transformation is phased, so all occurrences of getAnalysis<DominatorTree>(Function) happen before any occurrence of getAnalysisID<FunctionPass>(&DemoteRegisterToMemoryID, Function). If I register these two passes with DominatorTree first, I

Hi all, I have problem with ExtractCodeRegion (CodeExtractor.cpp). My original program is as follows. bb: ... %tmp.15 = load %struct.MYSQL_ROWS** %3, align 4 ... bb1: ... %tmp.1 = load %struct.MYSQL_ROWS** %6, align 4 ... bb4: ; preds = %bb1, %bb, %entry %tmp.0 = phi %struct.MYSQL_ROWS* [ null, %entry ], [ %tmp.15, %bb ], [ %tmp.1, %bb1 ]

Hi, I've seen this question asked before but I haven't seen an answer.. I would like to extract the body of a (for) loop into a new function so I can do some transformations. The function ExtractCodeRegion seemed like a good candidate and I've got it to sort of work. My problem is that ExtractCodeRegion creates a function that still contains a loop. I was able to eliminate the loop

I guess I didn't have a clear question. Suppose we have BB1 and BB2 both point to BB3. BB1 has variable x. BB2 also as variable x. BB3 will have PHINode for x with 2 value from BB1 and BB2. BB1 BB2 \ / BB3 Now if BB1 and BB2 is extracted into a function (using ExtractCodeRegion), they will be replaced by a basic block called codeRepl (which has a call to the extracted
