similar to: [LLVMdev] Heap memory allocation

I'm translating the source of stack-based virtual machine into LLVM IR and my plan is to implement the stack in LLVM IR (using alloca/load/store) in order to emulate the VM's stack and then use the optimization phase "mem2reg". Therefore I'm going to have a stack pointer that points to the top of my stack. I'm curious whether I will have to implement that in a

[I'm not subscribed to this list, please CC me on replies] Hi, well, the topic says it all ;) I want to know if it's safe to use them (yes, i know it's not safe, but if someone says 'they fucked my computer' i will know i can't use them. If noone says anything i will find someone to test them ;)) Thanks. -- Piotrek irc: #debian.pl Mors Drosophilis melanogastribus!

Hi, I am unsuccessfully trying to connect from host to containers dbus. Inside container dbus socket file is visible as /run/dbus/system_bus_socket. The problem is that /run is mounted as tmpfs in container (by systemd on container) and thus the directory content is not visible outside the container. Is there any way to make this file visible also outside the container? Regards, Piotrek

hi, i'm new to R and i discovered that for years people are complaining about lacking of very basic and hopefully simple things, like multiline comment, some marker for 'command doesn't end at this line' etc. so my question is why some of those things are still not implemented? is it because of compatibility/policy reasons? is R syntax done and any extensions are forbidden?

In the file \lib\Support\Process.cpp on line 60, it seems as though an unnecessary heap allocation and memory leak occurs. This is the offending code: static TimeValue getElapsedWallTime() { static TimeValue &StartTime = *new TimeValue(TimeValue::now()); return TimeValue::now() - StartTime; } The issue is that the StartTime variable's value is allocated on the heap, after which a

Hi, 1. A small question: How do I ensure memory alignment? I want all malloced memory, globals and functions to be 4-byte aligned. Does llvm have any ".align" keyword? I'm currently implementing a small scheme toy-compiler, and want to use the lowest 2 bits for type tags. It's Currently 380 lines of scheme-code[1], quite similar to the compiler in SICP[2], which I hope to get

Hi folks, this summer I will work with Richard Smith on clang devirtualization. Check out our proposal: https://docs.google.com/document/d/1f2SGa4TIPuBGm6y6YO768GrQsA8awNfGEJSBFukLhYA/edit?usp=sharing And modified LangRef http://reviews.llvm.org/D11399 You can also check out previous disscussion that was started before our proposal was ready -

In some language implementations, such as the Glasgow Haskell Compiler (GHC) and the reference implementation of Go, a thread’s stack is allocated as a data structure on the garbage-collected heap.  The garbage collector is free to move this data structure whenever it is invoked. Currently, GHC’s LLVM backend does not use the C stack.  However, there have been discussions about whether using the

howdy gurus, I'm new and green and I was hoping for a tiny bit of your expertise. I'm running out of virtual memory (heap?) when summing using tapply. I've already used --vsize=90M on my hpux machine. (details below) Can I pre-sort or something to prevent my error? thanks, John Strumila john.strumila at corpmail.telstra.com.au > gc()["Vcells","total"] [1]

Since the heap statistics were added, I have viewed thousands of rsync reports (with --verbose and --stats), and not once have I had a need for them. So for me, they're just noise. Here is a 3-part patch to v2.5.6 that treats --stats in a similar fashion to --verbose in that additional --stats will get you more statistics. For this initial case, there's only one additional level of

Newer versions of qemu use file locking for the images by default, and apparently that does not work with /dev/null. Since this test just calls qemu-img to get the format of an empty image, create a temporary one instead. --- tests/regressions/test-big-heap.c | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) diff --git a/tests/regressions/test-big-heap.c

Does llvm have any > ".align" keyword? In the medium term, we plan to add alignment requirements to the alloca/malloc instructions and to globals (vars/functions) but we do not have this yet. Currently

Hello, I'm trying to run the "TrueSync Desktop" app (the equivalent of Hotsync for non-Palm handhelds, but without any Linux port, unfortunately), and I get the following error: err:heap:HEAP_ValidateInUseArena Heap 40360000: in-use arena 403e7eb8 next block has PREV_FREE flag wine: Unhandled exception (thread 0009), starting debugger...

Hello, I'm implementing a custom Haskell-to-LLVM compiler, and in my experimentation, noticed that GHC is much slower than clang certain examples, such as the ackermann function. However, from reading their respective IRs (Cmm for GHC and LLVM for clang), I don't really see much of a difference. Here is a link to the numbers. (n, m) are the parameters to the ackermann function
