Hi all, after compiling R-3.4.2 on opensuse leap 42.3, make check failed. Until R-3.4.1 I never had a problem with these tests. No, the programm stops at the following line of tests/reg-tests-1d.R: > ## available.packages() (not) caching in case of errors > tools::assertWarning(ap1 <- available.packages(repos = "http://foo.bar")) > tools::assertWarning(ap2 <-

Hi everyone, I'm interested in variadic functions and how llvm handles them. I discovered that the Clang frontend is doing a great job at lowering the va_arg (precisely __builtin_va_arg) function into target dependent code. I have also seen the va_arg function that exist at IR level. I found some information about va_arg (IR one) that currently does not support all platform. But since 2009,

Hi everybody. I'm developing a D compiler using LLVM as backend (LLVMC [1]). Tonight I had a look at variadic functions, the thing is though, that I'm on x86-64, and the va_arg instruction is not working. I've posted a bug report: http://llvm.org/bugs/show_bug.cgi?id=1740 In there I posted the .ll test case: define i32 @test(i32 %X, ...) { %ap = alloca i8*, i32 1024 %ap2 =

When I use clang on an x86-64 to spit out the LLVM, like this clang -O -S -emit-llvm varargstest.c where varargstest.c looks like this int add_em_up(int count, ...) { va_list ap; int i, sum; va_start(ap, count); sum = 0; for (i = 0; i < count; i++) sum += va_arg(ap, int); va_end(ap); return sum; } I see LLVM that looks like it's been customized for the x86-64, versus

Here's how I got libshout to compile using .Net. The projects should import and convert to the new format fine. I haven't tried compiling icecast yet. Add vorbis.c and theora.c to the libshout project [not sure why there were left off, will cause link errors later if you don't] implement.h is include with pthreads-win32. It's in the pthreads.# (I've been using

Dear Duncan, thank you very much, that is it! Indeed, there was activated in my internet router the "telekom navigation help". When I am (or the system is) looking for an not existent url, this "help" opens its own website. After deactivation of telekom navigation help, the normal message (server not found) comes. I never gave attention to this "help", although it is

Hi, I'm new at this, I'm very confused, and I think I'm missing something important here. In our pet example we have this: > fm <- lme(Orthodont) > plot(Orthodont) > plot(augPred(fm, level = 0:1)) which gives us a trellis plot with the females above the males, starting with "F03", "F04", "F11", "F06", etc. I thought the point of
