similar to: [LLVMdev] variable arguement intrinsics

Hello, LLVM's intrinsic overloading mechanism does not currently support overloading on pointer types. Patches to implement this would be welcome.

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 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 aditya, There are two ways to cound the number of predecessors for each basic block. You can generate the control flow graph using the CallGraphScc pass with the granularity of basic block and can simply traverse the graph bottom up till the root. The number of nodes encountered would be the number of predecessors. The second way would be to use the special ;preds marker in the llvm IR. Each

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

I have a variadic intrinsic that is defined as something like this: def int_foobar : Intrinsic<[llvm_anyint_ty], [llvm_vararg_ty], [IntrNoMem, IntrSpeculatable]>; When I construct a call to the above intrinsic with IRBuilder::CreateIntrinsic, it mangles the intrinsic name with the return type (i64) and the actual argument

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, 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, So, we currently have gc.result.int, gc.result.float. gc.result.ptr, gc.relocate, and gc.statepoint. gc.statepoint's signature is fine with a iPTRAny as the first argument. gc.result is in trouble, because none of the signatures admit even a simple array of integers, and there's no aAny. And certainly no vectors. So we can get a gc.result.vector to add to this mess, and admit [1] to

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, 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 all, I'm proposing integer saturation intrinsics. def int_ssat : Intrinsic<[llvm_anyint_ty], [LLVMMatchType<0>, llvm_i32_ty]>; def int_usat : Intrinsic<[llvm_anyint_ty], [LLVMMatchType<0>, llvm_i32_ty]>; The first operand is the integer value being saturated, and second is the saturation bit position. For scalar integer types, the semantics are: int_ssat: x <

Hi everybody, I checked around examples for vararg intrinsics, but seems like no target or other parts in LLVM use intrinsics with llvm_vararg_ty as an input and adding such an intrinsics gives me a compiler error saying "unhandled MVT in intrinsics!". Are these kind of intrinsics still supported into LLVM? Cheers, Marcello
