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 : Intrinsic<[llvm_migrate_begin,llvm_vararg_ty],[IntrWriteMem],"llvm.migrate_begin">; //A section of the code which deals with the //"migrate...

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. //Additions made to Intrinsics.td file: def int_migrate_begin : Intrinsic<[llvm_i32_ty,llvm_vararg_ty], [IntrWriteMem],"llvm.migrate_begin">; //A section of the...

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 backend can understand? If it is possible to add the function...
