similar to: [LLVMdev] Bogus warning?

I don't understand your point. Which version is better does NOT depend on what inputs are passed to the function. The compiled code for (as per llvm) f1 will always take less time to execute than f2. for x > 0 => T(f1) < T(f2) for x <= 0 => T(f1) = T(f2) where T() is the time to execute the given function. So always T(f1) <= T(f2). I would call this a missed

Hi, Ive just downloaded and build the portable openssh-5.0p1 source on my Linux box, and when I add the CFLAGS '-Wshadow -Wpointer-arith -Wcast-qual -W' I get a lot of warnings of the following type: - -Wuninitialized is not supported without -O - cast discards qualifiers from pointer target type - warning: `foo' is not at beginning of declaration - cast discards qualifiers from

I'm attempting to build 4.2.0rc4 on a FreeBSD 10.0 system. There seems to be a problem with finding the system headers. Specifically lib/texpect/texpect.c seems to not be finding /usr/include/sys/signal.h Some hints on waf or building samba would be appreciated Russ Poyner The errors: make WAF_MAKE=1 python ./buildtools/bin/waf build Waf: Entering directory `/root/samba-4.2.0rc4/bin'

The patch there most likely is looking for signal.h in

The following seemingly identical functions, get compiled to quite different machine code. The first is correctly optimized (the computation of var y is nicely moved into the else branch of the "if" statement), which the second one is not (the full computation of var y is always done). The output was produced using the demo page on llvm's web site (optimization level LTO). Can

So any other ideas as to why my custom class under app/models is being cached even though all the caching is set to false in the config/environments/* files? Currently I''m having to restart WEBrick after EVERY change to the file. The controllers and views are reloading just fine and not being cached. It''s just the custom class I created that''s being cached. Any ideas

I'd consider this a bug in documentation as in the lack of documentation. I've looked all over the openssh.org Web site and done a number of Google searches and can not find anything. I'd like to know what error codes, if any, mean. For example, if I do an 'scp', and it fails, will it return a different error code depending on what the error was? Do I get one code if I

Trying to compile asterisk (again) from scratch. I seem to be still experiencing the effects fro Jan 25 where I get no sip to sip audio. I have tried upgrading to 1.2.3 which has made no change in the problem. I am starting over and now trying to compile/install /trunk zaptel libpri asterisk following the instructions to grab the source trees: # svn checkout

I have two offices sharing a phone system. They also share a common internal context because all of the employees of the second office also work for the first office. Each office has 4 outside lines and I have defined 2 channel groups in my zapata.conf. The second office needs all of their outgoing calls to go out over their lines so the people they call will have the correct callerID. I

For the simple C program below I show the output of clang and the output of the VS compiler (I am on windows). Maybe this is obvious to you, but is it really faster to do 2 multiplications, 3 movl instructions, 2 shifts, 1 add, and 1 substract than to do 1 mov, 1 cdq, and 1 idiv? I run into this while trying to understand why my code runs slower with llvm than a comparable program on windows.

Hi Brent, You're correct. The segmented stack model is intended for performance, not security. Its goal is to allow lightweight threads to be very cheaply allocated and destroyed. For your model, you would most likely want to use different address spaces for the different memory types. Currently, clang does not allow you to define the address space of variables with automatic storage

First off, let me state that I am not a C programmer at all. I am a programmer in other languages, so I understand the basic configure/make/make install procedure for most GNU packages, and have done it lots of times. I downloaded the GNU iconv libraries, compiled them and used --prefix=/usr/local/special to keep from replacing the standard AIX libraries. Then I downloaded the 3.0.2a source and

Hello, Hope everyone is enjoying their holiday! We setup two asterisk servers (From CVS on Wednesday) and set up IAX between the two. Right now they both reside on a switch with a static 192.168.0.x IP address. The first Server is .5 and the second is .30. Our dialplan seems to be working, however on the console we get a flurry of NOTICE and WARNING messages. NOTICE[1116941120]: File

Hi Duncan, It doesn't appear to be what I'm looking for as there is copying of the old stack to the new stack. Additionally, according to the LLVM docs on segmented stacks (http://llvm.org/releases/3.0/docs/SegmentedStacks.html) the stacklings are allocated memory from the heap. Since this places them all on the same memory segment, a read/write from one stackling could technically
