Hello, This is a proposal for implementing "module flags". Please take a look at this and give any feedback you may have. Thanks! -bw Module Flags Metadata Information about the module as a whole is difficult to convey to LLVM's subsystems. The LLVM IR isn't sufficient to transmit this information. One should instead use the llvm.module.flags named

Could you expand on likely uses other than ObjC? For example, should float ABI (soft/softfp/hard) be conveyed via this mechanism? deep On Wed, Jan 18, 2012 at 9:36 PM, Bill Wendling <wendling at apple.com> wrote: > Hello, > > This is a proposal for implementing "module flags".

Dear all, Me and the Garbage Collector doesn't understand each other... I'm on R-1.0.1 (I have requested an upgrade to the right local people), an osf1 system with an alphaev6 CPU. I have fair amounts of memory to use, but it seems to be used up pretty fast nevertheless. I'm now trying to see what the garbage collector does, I have inserted a gc(v=T) call at a spot in my code. I

Hi Sandeep, ObjC is the first place that I will use it, of course (we need it to fix LTO). Other uses will come along later. (I don't know enough about the float ABI issues to say whether they should be done via module flags or not.) The OpenCL people have a need for named metadata for their stuff. I would hope that module flags would be a good fit for that, but that remains to be seen. But

Hi, I currently write a LLVM backend for RPython, a programming language and toolchain to write dynamic language interpreters. For example, this toolchain powers PyPy, a fast Python interpreter. In the moment the implementation uses a shadowstack to manage garbage collection stack roots. To improve performance, I experimented with LLVM's garbage collection support. It works by marking a

Hi Does rJava offer a way to instruct the JVM to perform a garbage collection? Regards Ben

Hi, I think we are overloading the Layout references for garbage collection. If you are creating a reference (kindLayoutAfter) from A to B, that may not mean that you cannot garbage collect B for the end user. My thought on Layout references was that it only guarantees that atoms appear in Layout reference order. Why are we overloading this for Garbage collection (aside from saving space/code)

LLVM has GC possibility (llvm_gc_allocate). What compiler uses it? I try ldc D compiler but it not uses LLVM garbage collection but own in Tango library. -- View this message in context: http://old.nabble.com/How-start-with-LLVM-garbage-collector--tp29505874p29505874.html Sent from the LLVM - Dev mailing list archive at Nabble.com.

...preter, everything is fine and the data comes out how I would expect. But when I run the R code to carry out those steps, every now and again (Around 1/5th of the time), the returned data is garbage. I'm expecting to receive a bias per iteration that should be -5 <= bias <= 5, but for the garbaged data, I'm getting results of the order of 100s of thousands out (eg. -220627.7). If I call the routine which carries out the processing for one iteration from the intepreter, sometimes I get the correct data, sometimes (with the same frequency) I get garbage. There are two possibilities that I...

> LLVM currently lacks working examples demonstrating the use of garbage > collection... Hello, if anybody has time, I would recommend putting a big disclaimer at the top of the garbage collection page that explains that, for the most part, garbage collection falls outside of LLVM's domain. Right now LLVM advertises itself as "supporting garbage collecting", which although

Hi, I have a problem with a large data set wrapped in a reference class. I do that to access the data by reference from within various functions in a script. # The class definition: setRefClass("data", fields = list(h5_df = "list", training_data = "array",

Hi, I had a technical question about CHARSXP and garbage collection and couldn't find the answer in the R manual. The question is this. Are CHARSXP garbage collected like any other object, despite being part of the CHARSXP cache? i.e. is the cache being cleaned by garbage collection regularly and therefore, when I am in C code, do I need to protect a CHARSXP? Thanks! Holger [[alternative

Danila Sentiabov I am just as stuck as you. There is no way for Forum and Mailing list to PM each other. So that leaves me 1 option start a thread about it. I don't mind if other people chip in. All the things I call garbage reference sites have 1 thing in common. Failure to give credit to source of the information their instructions are based off. Lot are rewritten as if they are
