Hi all, I started to write an LLVM backend for custom CPU. I created XXXInstrInfo but there are some problems. I searched for it but I couldn't find anything. Can anyone help me? include "XXXInstrFormats.td" def simm16 : Operand<i32> { let DecoderMethod = "DecodeSimm16"; } def mem : Operand<i32> { let PrintMethod = "printMemOperand"; let

Hi Tom, Matt, I'm running into strange issues with the cos test (piglit generated_tests/cl/builtin/math/builtin-float-cos-1.0.generated.c) I have been seeing random failures (incorrect results) for some time and tried to investigate. the weird part is that the failures are not 100% reproducible, sometimes the tests pass, or partly pass (it's usually float8 and float16 subtests that

Hi, I''m currently trying to use a Linovo R61 Thinkpad equipped w/ Core2 Duo for HVM Virtualization. BIOS shows CPU/Virtualization->enabled. Xen 3.2.0 shows (Xeo) VMX disabled by BIOS Does someone knows any problems with R61 Thinkpads?

While researching Areski's new Web-MeetMe management gui, I found some odd (from what I expected) behaviour). Using the CLI to set un/mute status works but does not update the flags, or so it appears. Starting with a fresh conference (1 user) *CLI> meetme list 3456 User #: 1 Channel: OH323/R61 Using the CLI to mute the caller (no change in the user status0 *CLI> meetme mute 3456 1

Right before instcombine, we have this: %r60 = load <2 x i64>* %"$LCS_1", align 16 ; <<2

I'm targeting a machine that can only load and store aligned 64-bit words, but I'd like to be able to pack 8-, 16-, and 32-bit values into these words. Loads will require various shifts and masks; stores are more complicated. Does LLVM provide any support for such things? Is there an example target I can look at for ideas?

I am confused by this bit of code in instcombine: 09789 if (GetElementPtrInst *GEPI = dyn_cast<GetElementPtrInst>(Op)) { 09790 const Value *GEPI0 = GEPI->getOperand(0); 09791 // TODO: Consider a target hook for valid address spaces for this xform. 09792 if (isa<ConstantPointerNull>(GEPI0) && 09793

I've been testing my multi-stream mux directshow filter. And have created some files with 2 tracks of vorbis... varying from 2 mp3s transcoding to vorbis interleaved to one mp3 transcode to vorbis in one stream, and live muxed spoken audio encoded to vorbis in the other. Simliarly some with vorbis in one stram and speex encoded voice-overs in the other. My directshow filters can play these

Hi everyone, I experience some problems with adressing of data.frames when I retrieve some information for geographical position (ypos, xpos) ot of a MySQL Database and want to perform some simple statistics. The problem is adressing the dataframes with a construct like rawdata[c(type)] vs. rawdata$TEMPMIN to retrieve the numerical information and not a string (I want to store the numerical

Hi all, I am in the thinking phase of Vorbis 'file' to 'buffer' conversion. ie, accessing the stream data from the static buffer, rather than accessing the file from the decoder( the way it is implemented in the vorbis decoder). I am putting my understanding and the respective query below, As the general convention , there are two methods by which i can do this. 1) Assume what

Hello list, I cannot get make-kpkg to build a Xenlinux type kernel into a Debian kernel binary on my Debian Squeeze x86_64 system.
