...pon the predecessors of bb2 and bb3). You can also try to utilize the branching info at the end of each basic block in llvmIR of the source. I am working on something similar, do let me know if u need some specific information.

Hi! I want to know How to count the number of predecessors for each basic block? Thank You ____________________________________________________________________________________ Never miss a thing. Make Yahoo your home page. http://www.yahoo.com/r/hs

hi, how to get the number of immediate predecessors for each basic block (arguements of remarks statement at the beginning of the basic block) thank you aditya ____________________________________________________________________________________ Never miss a thing.

hi, how to get the number of immediate predecessors for each basic block of LLVM IR (arguements of remarks statement at the beginning of the basic block) thank you aditya ____________________________________________________________________________________ Never miss a thing.

Hi, I am writing a pass which identifies the parts(basic blocks/functions) of the input algorithm with more of data flow or control flow. These parts are to be separated executed by different backends. My idea is to insert replacement basic blocks with intrinsic instructions within the basic block. These instructions should satisfy the data dependencies within the LLVM data structure and should

Hi, I tried creating intrinsics which are to be placeholders for a set of instructions which should not be executed by the backend. In this process I want to replace the uses of each instruction with the intrinsic(Call) instruction. I am puzzled about the return type to be used in the intrinsic defintion(for creating the intrinsic) which is to be included in the Intrinsics.td file. Do we need

Hi, I have implemented intrinsics which are placeholders for instructions executed elsewhere (e.g. in HW). So i have two types of intrinsics migrate_begin and migrate_end. Now i would like to make these intrinsics known to the PowerPC backend. Since the hardware initialization can not be implemented by one instruction it has to be expanded to a library call or lowered to something the ppc

Hi, Thank You for the advice and we were able to solve that problem by the following modifications to the Instrinsics.td file. But I now have an "Invalid Intrinsic name" error This error occurs presumably because the created intrinsic is named: llvm.migrate_begin.i32 Intrinsics.gen checks for a string length of 18 (i.e. the length without the .i32). Kindly help me through it.

Hi, I tried creating intrinsics which are to be placeholders for a set of instructions which should not be executed by the backend. I get the following verifier error. The "indvar.next4" instruction being mentioned in the step wise debug is not present in the LLVM IR (i.e IR before application of my transformation Pass). As seen below the operands of this instructions causing

hi I want to use two intrinsic functions which should be placeholders for some instructions which should not be executed by the backend. So these two intrinsics should just keep the data dependencies while i try to separate set of instructions(with more of data flow) to be executed on hardware. One intrinsic which takes care of the data dependencies required for proper execution of the

Hi, I tried creating variable argument intrinsics which are to be placeholders for some instructions which should not be executed by the backend. Kindly help me with the errors in my "migrate_begin" intrinsic creation //Additions made to Intrinsics.td file: def llvm_migrate_begin : LLVMType<iAny>; def int_migrate_begin :

Hi, I tried creating intrinsics which are to be placeholders for a set of instructions which should not be executed by the backend. I want to retain only intrinsic,phi and terminator instructions in a basic block. I have taken care of the external dependencies of basic block. How do I delete the rest of the instructions?
