Hello, Everyone. Just few notes for everyone, who wants to build Qt with llvm. Everything was tested with shiny-new Qt 4.2.2 (X11 version) and llvm-gcc4 & LLVM from head. Instructions written here should also work on 1.9 release, as I've tested Qt build last time just before 1.9 release. 1. Specs Qt uses it's own configuration and build system called "qmake". We should

hi there I'm trying to get asterisk going on gentoo 2005.1 I'm just getting my feet wet so I thought I would just stick with the stable portage packages. Right now that's asterisk 1.0.8 I emerge asterisk with the following make.conf file: CFLAGS="-O2 -mcpu=i686" CHOST="i386-pc-linux-gnu" CXXFLAGS="${CFLAGS}" USE="-gtk -gnome -qt -kde -dvd alsa

Hello. I am making a LLVM backend for a new architecture XCC. During implementation of instructions for XCC, I found that there are instructions need more than 3 operands in the target language manual. I could implement insructions need 1, 2 or 3 operands thanks to the examples in the LLVM backends already offered by you guys. But, I am not sure about those kind of instructions needs many number

Hello, I am trying to calculate and plot mean and confidence intervall for a set of data.

Hi, I''ve a quad-core x86_64 machine (Intel Xeon), with sse/mmx support. However, I want to disable sse/mmx support from HVM guests. How can I do this? Also, is it reasonable to expect illegal instruction fault in non-root VMX mode if a guest VM runs an application with sse/mmx instructions? Thanks, Ashish _______________________________________________ Xen-devel mailing list

Hi all, I'm working on a graphics project which uses LLVM for dynamic code generation, and I noticed a major performance regression when upgrading from LLVM 2.8 to 3.0-rc1 (LLVM 2.9 didn't support Win64 so I skipped it entirely). I found out that the performance regression is due to removing support for lowering 64-bit vector operations to MMX, and using SSE2 instead. My code uses a

I have tried to compile kde window decorator, but "configure" don't check my Qt installation and it don't have a option to specify the path. Thanks for your

I recently diagnosed a bug in someone else's software, which turned out to be due to incorrect MMX intrinsics usage: if you use any of the x86 intrinsics that accept or return __m64 values, then you, the *programmer* are required to call _mm_empty() before using any x87 floating point instructions or leaving the function. I was aware that this was required at the assembly-level, but not that

Hi, When setting -mattr option on X86, I would like to treat MMX separately from SSE levels. This would allow a client who sets the attributes directly to set the SSE level independent of MMX, e.g., llc -march=x86 -mattr=sse41, one would get sse4.1 with mmx disabled while llc -march=x86 -mattr=mmx -mattr=sse42 will get mmx and sse42. If anyone objects to this change, please let me

This is a bit obscure but caused me some grief... R1.5.1/MS Windows There seems to be a peculiarity in legend associated with the use of expression text. It seems as if expression text is used in (eg) an mtext call then if the call to legend also includes expression text and a subscript then the legend box and line spacing depends on the value of cex used in the previous call to mtext,

OK , grepping the whole source tree for 'ctlz' I found the answer to my question in: test/FrontendC/2006-01-16-BitCountIntrinsicsUnsigned.c and that is to use gnu frontend style __builtin_clz() for this one. This test/FrontendC directory has a plethora of other usefull examples so I guess It will be sufficient for me. However I still think that some documentation of the frontend

Your clang invocation below works for me, and generates target triple in the llvm IR of i386. And then in the specific options for the functions it generates the following: ; Function Attrs: nounwind define float @foo() #0 { entry: ret float 1.000000e+00 } attributes #0 = { nounwind "less-precise-fpmad"="false" "no-frame-pointer-elim"= "true"
