Linux g++: how to prevent ALL functions being inlined | Bytes (2024)

member functions

by: Wenjie |last post by:

Hello, I read someone posted assertions that even the (public) member function is not static, there are probably only one copy of the code in the executable. Then except the dependency/independency on the lifecycle of the object, what is the significant differences between public member functions and public static member functions?

Inline Functions

by: A |last post by:

Hi, I'm having problems completing a project in C++. I have been using inline functions in some of my header files. I have only done so for simple functions that only have 1 statement (eg. accessor and mutator methods to access private data members). I would like to know if there are any issues with using inline functions that may have attributed to my errors before I start separting them out into "outline functions". Regards

Resolution of virtual functions

by: Aguilar, James |last post by:

I've heard that virtual functions are relatively ineffecient, especially virtual functions that are small but get called very frequently. Could someone describe for me the process by which the address of a virtual function is resolved and what the hidden costs associated with virtual functions are? I've heard the same of typeof (that it is inefficient if used in high traffic code) -- if you've the time, could you explain how typeof works...

inline functions

by: Rubén Campos |last post by:

I haven't found any previous message related to what I'm going to ask here, but accept my anticipated excuses if I'm wrong. I want to ask about the real usefulness of the 'inline' keyword. I've read many authors (and it's my belief, too) who discourage the use of the 'inline' keyword, because: - The 'inline' word only advice the compiler about wich functions should be expanded, but not force it to expand them. Also, the compiler can...

Inline functions and performance

by: Per |last post by:

Hi I am currently working on a mathlib and I want maximum performance (speed). If I delcare a function in the mathlib inline will the user apps take advantage of that or will it be called as regular function? So will a inline function from a lib file really be inline when I use it in different apps. ? /p

Scope of inline functions

by: Ondrej Spanel |last post by:

I though that inline functions should be always visible only in the compilation unit where they are defined - meaning if compiler cannot inline them, they should be handled as if declared static. However sample attached shows VC compiler does not work this way (tested in .NET 2003). When you compile the sample with inlining enabled (like in default Release config), the output is A1 = 1, A2 = 2. When run with inlining disabled (Debug),...

Inlined functions in mixed mode C++

by: Steve McLellan |last post by:

Hi, We've found some pretty serious performance hits that we didn't expect in a mixed mode C++ application. The number crunching bits of our algorithms are compiled with #pragma unmanaged. They call a number of inline functions elsewhere, and from the documentation my understanding was that inlined function calls are supposed to be effectively replaced by their implementation at compile time. This would mean that inline functions used...

Debugging C++ program in GDB on linux

I am trying to debug a C++ program in GDB on linux. I want to dump out the content of the "this" object, Here is what I get: (gdb) print *this $2 = {path = <incomplete type>} My question is why I don't see the content of 'path'? It said '<incomplete type>'. In the code, path is:

inline functions not inlined

by: Bilgehan.Balban |last post by:

Hi, If I define an inline function in one .c file, and use it from another, after compiling and linking the two, it seems the function is not inlined but rather called as a regular function. I would expect to see it inlined during linkage of the two object files. Does inlining only occur if the inline function is defined within the same file that it is called? Thanks,

why template functions in boost lib are all inlined?

by: newbie |last post by:

I happened to read boost library code and realized that most (the part I read) functions are inlined like: template <class Key> inline void Foo(const Key& k) { ... ... } Is there a strong reasoning behind this?

Problem With Comparison Operator <=> in G++

by: Oralloy |last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou |last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
