Hi, When using mips-unknown-linux-gnu as a cross-compiler, the llvm Mips backend is called by cc1 and with that you get llvm bytecode defined relative to the Mips ABI. This can be messing up somehow your generated C code. 2008/3/7, HyperQuantum <hyperquantum at gmail.com>: > On Fri, Feb 29, 2008 at 2:23 PM, HyperQuantum <hyperquantum at gmail.com> wrote: > > At least I got

Btw, cross-compiling llvm-gcc for Mips wont work since the support in llvm-gcc isnt ready yet! > Another option could be to add real support for the PSP

That was my intention. The PSP has a 32-bit MIPS (derived) CPU. What I don't know is if that triple is the right one

Hi all, Last year i was mentored by Chris Lattner at GSoC and i created the Mips back-end for LLVM. The back-end is still experimental (working with simple benchmarks only) and this year i would like to improve it as my GSoC proposal. Mips is still fairly used nowadays in a lot of devices - routers, wireless cards, PSP, PS2 - and it would be great to have a stable mips backend for LLVM. General

They're definitely not

Hi, I recently came across the following in __floatsidf in compiler-rt: __floatsidf(int a) { ... if (a < 0) { ... a = -a; In the case where a == INT_MIN, is this negation not undefined behaviour? AIUI this function is used for software emulation on targets that have no hardware floating point support. Perhaps there is an in-built assumption

Hi. : ) I was updating my unofficial Korean Ogg Vorbis FAQ, when I noticed the following: While #ext is no longer listed in the FAQ contents, http://www.vorbis.com/faq.psp#ext still exists. IMHO http://www.vorbis.com/faq.psp#stream looks a little awkward. I suggest something like: Icecast streams Ogg vorbis to playsers like XMMS, Winamp 2, and foobar2000, which are all capable of...

If you don't want to install it, you can run it as cd gcc && ./xgcc - B./ t.c.

I tried to cross-compile llvm-gcc for mips, but it crashes somewhere in the build process: /home/kevin/Documents/School/2eLIC/Thesis/work/build/llvmgcc-mips/./gcc/xgcc -B/home/kevin/Documents/School/2eLIC/Thesis/work/build/llvmgcc-mips/./gcc/ -B/home/kevin/Documents/School/2eLIC/Thesis/work/build/llvmgcc-mips/../../install/llvmgcc-mips/mips-unknown-linux-gnu/bin/

Dear List, I thought it might be useful if I wrote up my notes on getting an MGE UPS to work with NUT and openSUSE. The MGE UPS (an Ellipse 1500 USB) will work well with NUT and openSUSE 10.2, but not "out-of-the-box": there are some things you need to do: Intro. MGE have built rpms of NUT which greatly simplify installation. Merci MGE. I used the rpm's for nut-2.0.5 and the

Hi Kevin, > Supposed that you knew my approach was intentional (correct me if I'm > wrong), what problem did you see here? Yes, i'm trying to help raising possible problems. For example, there are Mips machines with different endianess, the llvm Mips default (Big) is different from the psp toochain default one (correct me if I'm wrong - Little), maybe this is messing up...

Hi, I'm forwarding your mail to the NUT list, because of a lack of time, and also since some others (Charles) already looked at this issue IIRC (related to the development branch 'netport'). cheers, Arnaud -- Linux / Unix Expert R&D - Eaton - http://powerquality.eaton.com Network UPS Tools (NUT) Project Leader - http://www.networkupstools.org/ Debian Developer -

Hi, I recently bought a MGE protection center 500. I am running a gentoo, and I am currently trying to enable the ups handling by the os, with no success. First, I compiled and installe nut 2.0.2 (with usb support) and psp 3.0. I made ebuild for them that I will submit soon to bugs.gentoo.org. The ups is connected via usb, and lsusb confirms that the device is detected (cf end of the mail for
