Below is a toy alt-rep string example, that generates N random strings: https://gist.github.com/traversc/a48a504eb062554f2d6ff8043ca16f9c example: `x <- altrandomStrings(1e8)` `head(x)` [1] "2PN0bdwPY7CA8M06zVKEkhHgZVgtV1" "5PN2qmWqBlQ9wQj99nsQzldVI5ZuGX" ... `object.size(1e8)` Object.size will call the `set_altstring_Elt_method` for every single element, materializing

Hi Tim, The global merge pass puts the GVs into a sturcture to guarantee their address are contiguous. It works for static GVs but for global hidden GVs, this will cause name resoltion fail during linking .o into .so Any thoughs?

You should really take this up with RStudio. Calling object.size on every top level assignment as they appear to do is a bad idea, even without ALTREP. object.size is only a cheap operation for simple atomic vectors. For anything with recursive sturcture it needs to walk the object, so the effort is proprtional to object size: > x <- rep("A", 1e8) > system.time(object.size(x)) user system elapsed 1.222 0.624 1.850 > x <- rep(list(1), 1e8) > system.time(object.size(x)) user system elapsed 1.247 0....

Hi, When I’m compiling a code with –fvisibility=hidden –fPIC for ARM, I find that LLVM generates less optimized code than GCC. For example: test.cpp: void init(void *); int g0[100]; int g1[100]; int g2[100]; void foo() { init(&g0); init(&g1); init(&g2); } Clang will emit 1 GOT entry for each GV and 2 instructions to get the address: ldr

Hello all: I know I had posted this question a while ago, but I have just not been able to get it to work. I am trying to sync samba passwords with unix passwords and it is just not working. I have attached the results of "testparm -sv /etc/samba/smb.conf > smbconfig.txt" with this email. I have also attached the "net groupmap list" results. If anyone can provide any

At the moment, we translate the virtual address from the guest in the page-fault-handler to guest physical address via the gva_to_gpa() function in svm.c/vmx.c:

Hi, I just read this blog article from austrian Linux expert Michael Kofler. For those among you who don't know the guy, he's my home country's number one Linux expert (known as "der Kofler") and most notably the author of a series of excellent books about Linux over the last 25 years. https://kofler.info/centos-8-wertlose-langzeitunterstuetzung/ Disclaimer : I've been
