[LLVMdev] What happened to XCHG_rr?
Hi, guys, What is the opcode of the instruction to swap two registers in X86? After updating my LLVM branch, I realized that there is no longer an opcode for xchg with two register operands in X86GenInstrNames.inc. I found only instructions to swap memory and registers: XCHG16rm, XCHG32rm, XCHG64rm and XCHG8rm. I am updating from LLVM 2.1 to current trunk. The names that I was

[LLVMdev] What happened to XCHG_rr?
I was using them to do SSA-elimination after register allocation. I can implement swaps using three XOR's, but then the code becomes a little bigger and slower. I think even for the sake of completeness, the X86 back-end should offer the possibility of swapping two registers with one single instruction. Do you guys think there is any possibility that those instructions could come back to

[LLVMdev] FYI: Removal of XXXRegisterClass from GenRegisterInfo.inc
In r155270, I removed code from TableGen that emitted XXXRegisterClass into GenRegisterInfo.inc. This value was just a const pointer to XXXRegClass. So all places that used XXXRegisterClass should be changed to &XXXRegisterClass. I already did the conversion for all targets in the tree so this is a notice to out of tree targets. One of the most common place you might find this is setting up

fsincos emulation on AMD CPUs
All, in the light of erratum #573 I''m wondering if we need to tweak or conditionally suppress fsincos emulation. The question is whether there is any possibility for getting the emulator to hit this instruction on AMD (as no real mode emulation ought to be taking place there), i.e. whether there are places where emulation gets continued eagerly in anticipation of the need for emulation

[LLVMdev] llvm backend porting question ,
I start my porting for picoblaze,the soft cpu for fpga ,which is designed by XILINX from MSP430 porting . After some day's work , somethinig looks good , for it can generate for some simple C program: eg : int f1(int a) { return a+1; } but it failed with this : char f() { char a; a++; a++; a++; a++; a++; a++; a++; a++; a++; a++; a++; a++; a++; a++; a++;

[LLVMdev] execution time of bytecode and native
Hello , I am compiling SPEC 2000 benchmarks with llvm .Got stuck with calculating "execution time" of all the .bc and native files. The log for nightly test itself gives execution times but I am passing the bytecode files to my pass which gives another bytecode file.I have to calculate execution time of such bytecode and native files as well.If i simply do this: time lli

[LLVMdev] execution time of bytecode and native
Hello All, Thanks for the reply.I can generate the reports by compiling Spec through llvm, but that couldn't resolve my problem. I m trying to determine execution time for the bytecode and native files , which are obtained as a result of running my pass over the original bytecode .I am running these experiments on spec benchmark. In SPEC we have command line tools such as runspec where

Joining samba4 as a DC to Windows Server 2012 active directory

grouping in scatterplot3d
Hi all, I've been using the scatterplot3d function (from the scatterplot3d library) to create 3D plots. I was wondering whether there is anyway to group the points according to a particular group variable. For example I used the plot function as plot( factor( <GROUPINGVAR> ) , <PLOTVARS> ) to organise the results in a according to the grouping variable. I was wondering

Hi all! The following files emits warnings when compiled with gcc 4.0: al175.c bcmxcp_ser.c belkinunv.c cyberpower.c everups.c powercom.c solis.c All warnings seem to be of this variety: everups.c:38: warning: pointer targets in passing argument 2 of 'ser_get_char' differ in signedness I suggest that those who fiddles with those drivers fixes the warnings and verifies that it works

how many 7th of the month is there between two dates
This is a eaeir way to ask my prior question: I want to caculate how many an exact day of the month there is between two dates. For example; How many 7th of the month is there between "1998/12/17" and "2000/1/7". To make the problem simple, the day of the month (7) is the day in the 2nd date.

Publishing a webcam on a web page?
This talk of cameras has reminded me of a problem I've not yet been able to solve. I have a Logitech Communicate STX ( ID 046d:08ad Logitech, Inc. QuickCam Communicate STX ) This seems to work under v4l on CentOS 5.4. If I load xawtv (from rpmforge) then I can view the image from the camera.

I'm not the originator. I'm just trying to do some maintenance on the code to make it work for CentOS 7. I'll check out those two. Any ideas on how to check exactly what's sent via the socket?
