Forcing a call statement to use a fixed address call when compiling?
Hey guys, I have a very specific question regarding how to force a fixed address call instead of a fixed offset call. I am looking to force a fixed address call so that the location of the function bar() below can be modified at runtime. int foo() { return 0; } void bar() { foo(); <-- After compiling, this is translated into a fixed offset call instruction: call 0x(Offset to foo) } I know this is one way of solving the problem, but I was wondering if there is a better way of achieving this? int foo() { return 0; } void bar() { int(*fooPtr)() = foo; fooPtr(); <-- This will make a fix...

What is the different between c++ call convention and c call convention?
What is the different between c++ call convention and c call convention?Can some give some examples?

Neither C nor C++ define a "calling convention". Particular compilers provide their own "calling conventions", generally based on the underlying processor architecture and usually also on the operating system that the code will run under. If you are interested i...

Can i use a compiler A to build an application that uses libraries built with compiler B ?
Hi I am facing a problem to build a c++ application. It uses libraries that are build with gcc. The libraries are C libraries and not C++ libraries( and i cannot build these C libraries using C++ compiler because i don't have the source code) The application that i am trying to build is being built with CC compiler of Sun on Solaris and the application is C++ application. I am facing linker errors.( of course the C headers provided with C libraries are using extern "C") My conjecture is that this is due to use of different compilers to build the application and the libraries being used by the application. I have read somewhere that C++ libraries are not portable in i.e i can't use c++ library built with compiler A in a application(C++) that is being built with application B and this is due to different calling conventions of different compilers. But i am not sure whether a C library is portable or not. Please correct me if i am wrong in any of my above statements. I have already read the faq http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html and here also it is mentioned that the compiler should be from the same vendor( if you want to mix c and c++ code) But my colleague says that his application( with the same scenario) is being successfully built and mine is failing because of some other reason and not the one that i believe. Am i wrong ? Then how come that he is able to build their application using same libraries and my application is gi...

Help in using matlab in calling ni-daq function using direct DLL calls
I am new with matlab and i need your help in calling out an ni-daq function using matlab which is AI_Change_Parameter (deviceNum, 2, ND_DSA_EXCITATION, ND_ON); IEPE excitation generates a significant DC offset in the signal, and you will almost always want to enable AC coupling to remove this offset. Input coupling is also controlled using the AI_Change_Parameter function. To enable AC coupling on channel 2, you would make the following function call: which will enable me to control the Integrated Electronic Piezoelectric (IEPE) current excitation for my ni-4472 daq card.

Using the GCCSDK to compile a compiler
Hi, Given that there is a port to ARM Linux (Debian) of Novell's Mono .NET package, I'm guessing that it should be possible to compile the source up using the gccsdk (I'm not saying that it would work without being able to generate RISC OS binaries of C# code, but the source should compile). Now, I've been hacking around with Mono for quite a while and know the internals - what I don't know is how I would use the gccsdk to compile up Mono - does anyone have any hints or tips for doing it? I'll need Peter's config scripts, but there in lies a potential problem - Mono doesn't use configure rather it uses autogen.sh. Will the scripts cope with this?

Using the default package
Hi, I know that it is illegal to use a class from the default package in a named package. But JBuilder 7 is able to somehome circumvent this problem even though it is set up with a recent sdk. Does anyone know if JBuilder sets a special flag that I can also set manually to get the same effect? I'm using badly written libraries that put some key classes in the default package. Thank you very much in advance. A positive response will make my life a whole lot easier.

how to pre-compile and cache regex patterns in an Expect script for use between expect calls
Hello, Is it possible to pre-compile a regex pattern for expect, and then specify this pre-compiled version as a pattern directly within a Tcl/Expect script? I'm dealing with a script that is looking for the same pattern in volume quantities, and I'm wanting to make the script more efficient for the CPU. I've considered using string commands instead, but regex makes what I'm trying to match/capture easier, and so I wanted to see if this was possible. I'm looking at pg. 501 in Don Libe's Expect book, and wondering if I can use some form of "exp_compiled" tht is mentioned regarding use of the expect.h library directly in my Tcl/Expect scripts. Thanks in advance, David Basham David Basham wrote: > Is it possible to pre-compile a regex pattern for expect, and then > specify this pre-compiled version as a pattern directly within a > Tcl/Expect script? I'm dealing with a script that is looking for the Depending on the C code that expect is using, Tcl does cache regexps as objects. If you treat that always as a regexp, then it will only be compiled once at the C level. Of course, that assumes that Expect is using Tcl_GetRegexpFromObj (would have to verify). > more efficient for the CPU.

DSP using a non DSP processor
My requirement is to use a moderate controller (Non DSP) and take analog sinusoidal signals (half second cycle 50 hz) , take their samples, do a Fourier transform to remove harmonics and then multiply them to find instantaneous power. Then do a Low Power Filtering operation on this power signal. Is it possible? has anyone implemented anything similar or am I being too ambitious? please post your comments about its feasibility.

Use DEFAULT CONSTRAINTs or BOUND DEFAULTs?
I am doing a little research on Google about this topic and I ran into this thread: http://groups.google.com/group/microsoft.public.sqlserver.programming/browse_thread/thread/63cce060ff152dcc/1dc13d4ee6758966?lnk=st&q=difference+constraint+sql+defaults&rnum=14#1dc13d4ee6758966 I read SQL Server MVP Louis Davidson's post saying: "Actually they are more likely to drop the concept of bound defaults. Constraints are the standard way to do this, and really should be the way you create defaults anyhow." Even I read in the Microsoft SQL Server Introduction (SQL 7 book page 244, however we're using SQL Server 2000): "Constraints define rules regarding the values allowed in columns and are the standard mechanism for enforcing integrity, preferred over triggers, rules, and defaults. They are also used by the query optimizer to improve performance in selectivity estimation, cost calculations, and query rewriting." Why constraint defaults are better? The second sentence about constraints having better optimization, I am guessing they don't mean this about Default Constraints, rather the other type of constraints? Because I don't see how a Default Constraint have anything to do with performance? Isn't default only to do with new records being created? At work we are setting all tables' columns to have constraint defaults of 0 or ' ' (space character) in order not to have any column with the NULL value. Therefore we have ...

Default & non-default compilation semantics

In a traditional xt is CFA, immediate flag forth; "Words without interpretation semantics and with default compilation semantics (e.g., EXIT) can be implemented as non-immediate; you cannot implement them as immediate words if you support [COMPILE]." Does this mean "you cannot [COMPILE] EXIT" if EXIT is immediate? Clarification of the definition of "non-default compilation semantics" might help; I can't see the difference between IF and EXIT.

Putting call/2 and call/3 to some extreme use
Dear All Just noticed some funny use of call/2 and call/3. Namely call/2 can be used to implement is/2 as follows: X is Y :- number(Y), !, X=Y. X is Y :- call(Y,X). +(A,B,C) :- X is A, Y is B, sys_add(A,B,C). etc... And call/3 can be used to implement phrase/3 as follows: phrase(A,I,O) :- call(A,I,O). ,(A,B,I,O) :- phrase(A,I,H), phrase(B,H,O). '[]'(I,I). '.'(A,B,[A|I],O) :- phrase(B,I,O). etc..
