Hi, I'm trying to annotate certain functions in C code, and do something with these functions in my LLVM pass. I annotate the C code like this: int __attribute__((annotate("annot"))) function() { This nicely gets added to the LLVM bitcode in an @llvm.global.annotations global. Now I had hoped that it'd be easy to extract a list of functions annotated with my annotation

Hi all, I've also been developing an interest in using IR annotations for my compiler. Some discussion with Bart turns out that he has implemented some code to parse the llvm.globals.annotations array, but in no way integrated or reusable. We've spent some thought about how this could be done properly, which I will share here. Firstly, however, I was wondering about the format of the

I'm seeing a segfault on x86_64 Linux with the following code: desc = read.dcf("BAD") con = gzfile("test.gz", "wt") write.dcf(desc, file=con) close(con) where BAD has a long field (see below for example). The crash happens inside dummy_vfprintf. I think the issue is that the va_list ap is modified by the first vsnprintf call

Hello everyone, I am able to work very well with annotations in C/C++, by using __attribute__((annotate("MYANNOTATION"))) static int a; . Inside the LLVM bytecode I have @llvm.global.annotations and @llvm.var.annotation. However, I was trying to test annotations also in Java, with VMKit. These are the commands that I run: javac -Xlint -g -O Main.java ../Release+Asserts/bin/vmjc Main

Hello Harris, Thank you for your answer. So it is there a way of annotating variables in Java Code, so I can see them into LLVM bytecode? Thank you !

Hello Alexandru, No you did nothing wrong. We are using our own data structure to describe annotations in J3. So it is normal that you can not see your Java annotations inside the LLVM bytecode produced. If I remember well, our implementation of annotations do not rely on LLVM annotations.

Having multiple different uses cases during the bring-up would be very helpful to

Hi all I have a project where LLVM annotations could be very useful. My current understanding of LLVM in general is still limited, hence a nice interface to annotations or sample code that uses annotations would help me to get started. I was wondering what happened to the proposal for a better interface to handling of annotations, which has been discussed in this thread back in July.

hi Chris! thanks for your reply. First of all I did not know about the history with the Annotation stuff. Annotable for me was a way how one could realize this things. So as I see it right now - it is more that Annotable will completly vanish soon. This is interesting to me.

The following is a brief proposal for annotated assembly (and disassembly) output. Kevin Enderby and I have been discussing this a bit and are interested in getting broader feedback from interested folks. LLVM Rich Assembly Output LLVM's (dis)assembly output is currently very raw. Consumers have limited ability to introspect the instructions' textual representation or to reformat for

hi all, out of a matter of fact I am still using llvm version 1.5. I don't know how 1.6 works in this matter. When translating a complex c application to llvm bytecodes, some semantics are lost: Take for isntance the interesting attribute to put a variable in the thread local data section (.tdata), this would be interesting to have in llvm. like in GCC you write: int x

How can they processed? I cant seem to find any solid information about how they exist in IR form from a Passes perspective. I see things like @llvm.var.annotation in dumps but no relevant sounding methods to get at these.
