Thanks. I've rebased this patch on top of the recent LLVM (it was straightforward) and applied it in my fork. It seems to have solved one of the problems I was having. Would LLVM be interested if I submit the updated version for the review? -- Danila From: Philip Reames [mailto:listmail at philipreames.com] Sent: Tuesday, August 13, 2019 19:01 To: Danila Malyutin <Danila.Malyutin at

I've noticed that there was an attempt to mitigate ExitValues problem in https://reviews.llvm.org/D12494 that went nowhere.

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

A little more info: I was mistaken in saying that the garbage on the screen doesn't interfere with typed commands/stanzas; it does. If I can type the name of a stanza and hit enter quickly enough before the garbage is spat to the screen, it seems to start loading a kernel, but then it aborts. And the garbage appears to be varying quantities of '[0n', as in sometimes there will be one

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

Hello, I have some graphics problems with Dark Crusade. I have tested both windowed and fullscreen with lowest settings, it makes no difference. It plays fine in highest settings in Windows, so my graphics card is not the problem. Maybe the drivers for linux is crappy or something, but i havent experienced anything like this before in any other game.

In my package [1] I open handles to temporary files from c++, pointer to the objects containing those handles are returned to R as external pointer objects. The files are deleted when the corresponding R-object is deleted and the garbage collector runs: a <- lvec(10, "integer") rm(a) Then when the garbage collector runs the file is deleted. However, on some platforms (probably

Hi Hal, I see. So LSR could theoretically counteract undesirable Ind Var transformations but it's not implemented at the moment? I think I've managed to come up with a small reproducer that can also exhibit similar problem on x86, here it is: https://godbolt.org/z/_wxzut As you can see, when rewriteLoopExitValues is not disabled Clang generates worse code due to additional spills,

Thanks for the example code. Its gives a good idea how the shadow stack works. But I have another question. Using the shadow stack is a nice and simple way to implement GC, but it might have a large runtime overhead per function call. Is there another way to preserve garbage specific information (gcroots) through the llvm optimizer and native code generator? This information could be used to

Do you really, really need to run the garbage collector? Consider reading: https://stackoverflow.com/questions/5086800/java-garbage-collection Regards Martin

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

Hello, I want to add garbage collection support to a compiler with a llvm backend, using the shadow-stack compiler plugin. I read the GC tutorial in the LLVM documentation, and the paper about shadow-stacks. Im currently adding intrinsics to my generated llvm code, and trying to write code to connected it to my (existing) garbage collector library. Im not sure yet how everything fits together.

I have a Xerox Phaser 3250 printer It worked perfectly under Centos 6 when I told cups that it was a Xerox Phaser 3150. It works under Centos 7, too. I can print pdf files from evince and whatnot with no problems, and printing one, two or three copies of a document from libreoffice works as well. However, if I tell libreoffice to print four copies of a document ("number of copies"

Hi, In line 5, you are allocating a vector of length nc. Then, in line 12, you are using nr as a limit, so if nr goes beyond nc, which is happening in line 39, you are in trouble.
