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

...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).

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 types i32.i32. The mangled name then becomes @llvm.foobar.i64.i32....

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 was talking with aKor in #llvm how we could implement custom operation support for our ASIP architecture. We came into solution that the best way would be to write new custom operation intrinsic and optimization pass for raising certain type of function calls to those intrinsics (similar to raising mallocs). Basically our custom operation are like calls, with operand name and multiple
