What is the correct Targettripple for generating a X86 COFF-Files on windows?
Just got started and stuck at the same time. Working with the C-Api, i have come to the point where i want to emit a binary file for my module. I queried the X86-Target and called LLVMCreateTargetMachine this way: > LTarget := LLVMGetTargetFromName('x86'); > LMachine := LLVMCreateTargetMachine(LTarget, 'i386-win32-msvc', nil, > nil, LLVMCodeGenLevelDefault,

Optimizer issues on Windows
This got me into thinking. Indeed the problem is related to Windows exceptions, so I am not sure whether the bug reported<https://llvm.org/bugs/show_bug.cgi?id=24374> is actually fixed. Compiling Pony code (helloworld) that includes no exceptions does work fine (with optimizations). As soon as exceptions on windows come into play, writing the object file dies with the mentioned error in

Noisy benchmark results?
Hi, I'm trying to run the benchmark suite: http://llvm.org/docs/TestingGuide.html#test-suite-quickstart I'm doing it the lnt way, as described at: http://llvm.org/docs/lnt/quickstart.html I don't know what to expect but the results seems to be quite noisy and unstable. E.g I've done two runs on two different commits that only differ by a space in CODE_OWNERS.txt on my 12

Noisy benchmark results?
Two other things: 1) I get massively more stable execution times on 16.04 than on 14.04 on both x86 and ARM because 16.04 does far fewer gratuitous moves from one core to another, even without explicit pinning. 2) turn off ASLR: "echo 0 > /proc/sys/kernel/randomize_va_space". As well as getting stable addresses for debugging repeatability, it also stabilizes execution time

Dear Ren Yongjie
Hi Yongjie, I have just compiled and installed Xen 4.3-unstable changeset 26666 and Linux kernel 3.8.1, according to your specifications. However, I still cannot get success with Intel HD Graphics 4600 IGD VGA passthrough. Although in Device Manager in Windows 7 HVM domU, it says "This device is working properly" for Intel HD Graphics 4600, I can only get 16 colors. Please refer to

faster base::sequence

X11 plot window doesn't show graphic immediately
Hi r-help, I have a weird problem. When I plot anything, say plot(1:10), a plot window opens but it's empty. It looks just like this: http://i.imgur.com/9uqO6.png I have to resize the window, either by clicking the fullscreen icon on the menu bar, or by dragging the borders. Then the plot is shown, but strangely in the original size of the window, where it was before the resize:
