[LLVMdev] Ocaml bindings in 2.8
...it here. In the future you could either file a bug report or send the patch to llvm-commits. If no one replies, feel free to let me know directly, since ocaml patches don't come around that often so I may miss one here and there. Also, I fixed the llvm_params bug in trunk, as well as exposed a num_operands and a set_operand for you.

Redundant load in llvm's codegen compares to gcc when accessing escaped pointer?
...oc, or the so-called "struct hack": http://c-faq.com/struct/structhack.html For example: typedef struct { enum inst_type type; unsigned num_ops; struct operand ops[1]; } inst; // allocate an instruction with specified number of operands int *allocate_inst(unsigned num_operands) { char *mem = malloc(sizeof(inst) + sizeof(struct operand) * (num_operands-1)); return (inst *) mem; } Or maybe the reasoning is that computing a pointer off the beginning of something (e.g. &c - X) is somehow worse than computing a pointer off the end of something (e.g. &c + X...

Redundant load in llvm's codegen compares to gcc when accessing escaped pointer?
Reply from Michael: &x points to the start of object x, and &x - something (something != 0) points outside object x. 'c' was a complete object, so &c-8 points outside any object, hence the formation of that pointer is already invalid (as is its dereference). https://gcc.gnu.org/ml/gcc/2016-03/msg00185.html >>On Fri, Mar 18, 2016 at 8:46 AM, Daniel Berlin <dberlin

[LLVMdev] Ocaml bindings in 2.8
Hi, Does 2.8 release plan to change anything in Ocaml bindings? http://llvm.org/docs/ReleaseNotes.html#whatsnew does not list any relevant features. 2.7 added 'operand' that can access each operand from a value. external operand : llvalue -> int -> llvalue = "llvm_operand" Does this binding also expose a primitive to return how many operands a given value has? I need
