Hi all, I am creating a function and trying to call it using the LLVM API. It seems that whenever the function type includes an opaque-typed parameter, the CallInst::Create call causes an assert: Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!"), function init, file /usr/home/csanchez/shared/prj/tce/ src...

When running on PowerPC, we don''t have native PIO support. There are a few hacks around to enable PIO access on PowerPC nevertheless. The most typical one is the isa-mmio device. It takes MMIO requests and converts them to PIO requests on the (QEMU internal) PIO bus. This however is not how real hardware works and it limits us in the ability to spawn eventfd''s on PIO ports

Can anyone tell me where my blunder is in the following program? llvm-as reports: llvm-as: testit.ll:11: Can't store 'opaque *' into space of type 'opaque *'! Which doesn't seem to make sense to me. What is it that is illegal about storing a pointer to opaque in a space that is of type pointer to opaque? Is it just that you can't store pointers to opaque? %path = internal constant [11 x sbyte] c&quo...

Hello LLVM, I'm playing with a new ISD::OPAQUE instruction to make hoisting first class and eliminate a lot of tweaky flag setting/checking around opaque constants. It's going well for the IR and x86, but I now I need to sort out details for all the other targets. To start, can someone please advise on the AAarch64 equivalent of these X86...

** INCOMPLETE ** This is the generator change as discussed on the list already. The Python and OCaml bindings are not yet done. It passes all [C only] tests and valgrind. Note that nbd_add_close_callback is inconsistent with other closure types because it passes the user_data parameter after the function. (This is not caused by the current patch, it was already inconsistent). We decided that

...r 'callback' is the best approach or most idiomatic OCaml - but hey, it taught me a lot about OCaml. Writing a 'string * callback list' proved to be a rather interesting exercise] Our C code has a couple of functions that want to take multiple callback functions that share a single opaque data (nbd_aio_pread_structured_callback; nbd_aio_block_status_callback). However, the mapping of this construct to Python passed only the opaque handle of the first function to the second callback wrapper, which means we would invoke the wrong Python Callable; better is tracking a single malloc()d...

Posting now that I got something to compile (at the expense of breaking OCaml bindings), but I'm open to ideas on how to improve it.

...runtime library that contains some support routines called by generated code. The IR module contains calls to "malloc", which depend on the size of "size_t". Since I don't know the target when writing the IR module for the runtime library, I thought about using an "opaque" type instance in place of "size_t". When loading the IR module, I would refine the "opaque" to either i64 or i32, depending on which target I'm using. For example I currently have ; these opaque types are replaced at load time by codegen::RuntimeLib %sizet...
