Hi, after working with llvm for a while, I'm still a little confused with the meaning of the 'byval' attribute. From the langref: "This indicates that the pointer parameter should really be passed by value to the function. The attribute implies that a hidden copy of the pointee is made between the caller and the callee, so the callee is unable to modify the value in the callee.

Hi, byval means that the parameter setup code for performing a call copies the struct onto the stack, in an appropriate position relative to the other call parameters. > I'm particularly confused by the "between the caller and the callee" part. The > way I see this, the responsibility for the copying should be with either the > caller or the callee, It is with the caller.

Hi Tim, Thought about it last night and was coming to the same conclusion. 1. it cant be done at the end during lowering (target backend). 2. it should be part of llvm as the byVal needs to be handled. As a twist, I have been told that llvm-gcc can lower byVal into memcpy in the callee. I may take a look at this. I wonder if it ever emits 'byVal'... I still feel I don't understand

I was trying to do a SIP call between two Asterisk servers (1.4.21.2) 1) On the caller server, I coded the following in extensions.conf Dial(SIP/1166:password at asterisk-callee); 2) On the callee server, I coded the following in sip.conf [1166] type=friend ; Friends place calls and receive calls context=incoming ; Context for incoming calls from this user

Hi Robert, suppose you have a "byval" argument with type T*, and the caller passes a T* called %X for it, while in the callee the argument is called %Y. The IR level semantics are: (1) a copy should be made of *%X. Whether the callee or the caller makes the copy depends on the platform ABI. (2) in the callee, %Y refers to the address of this copy. There are many ways (1) can be

Hi, I'm trying to inline function defined in another bitcode module via bitcode modification. I'm linking multiple bitcode modules, setting inline related attributes, applying -always-inline pass, but then debug info error occurs. It seems debug info metadata isn't properly updated on inlining. How can I fix it? I'm using LLVM 3.8.1 on OS X (On below example target is Android but

TLDR - I have a runtime which expects to be able to inspect certain arguments to a function even if that argument isn't used within the callee itself. DeadArgumentElimination doesn't respect this today. I want to add an argument that records an argument to a call as live even if the value is known to be not used in the callee. My use case ----------------- What my runtime is doing

Hi. I have a beginner conceptual question about Asterisk: Let's suppose that there are 4 softphones registered in my Asterisk and all of them are currently online. In addiction , there is no call. Suddenly, one of these softphones sends a SIP message to the Asterisk. In this case the dialplan will execute the instruction ' exten => 2005,1,Dial(SIP/2000&SIP/2001&SIP/2002,

Hi, I'm trying to replace function call with call to wrapper(function_name, num_args, ...), where varargs hold args of original call. Function* launch = Function::Create( TypeBuilder<int(const char*, int, ...), false>::get(context), GlobalValue::ExternalLinkage, "kernelgen_launch_", m2); { CallInst* call = dyn_cast<CallInst>(cast<Value>(I)); if

> Every inlinable call in a function that has debug info (F->getSubprogram() returns non-null) must have a DebugLoc associated with it that has a scope chain that ends in that same DISubprogram. Thank you for the comment! I don't know if this is a proper way to fix, but after I add DebugLoc same as inserting position instruction, no error occurs.

I am using EQTDDataStructures (from the poolalloc project) to resolve indirect function calls to over-approximated sets of possible callees. Unfortunately I find that it yields incorrect results even on a very simple test input. My LLVM and poolalloc sources are Subversion trunk checkouts, no more than a day older than the current trunk head. My test input is the following C source, compiled to bitcode using Clang: void foo();...

Every inlinable call in a function that has debug info (F->getSubprogram() returns non-null) must have a DebugLoc associated with it that has a scope chain that ends in that same DISubprogram. https://llvm.org/docs/SourceLevelDebugging.html discusses some of the debug info IR metadata in LLVM.

Hello everybody, Do I understand correctly that Asterisk does not support sending INFO request? Here is the goal I want to accomplish and I'd be happy to hear how can it be done with asterisk. Asterisk needs to dial out and after successful call establishment it needs to send in-dialog INFO request to the callee and wait after that for another INFO message coming from callee. So call flow
