I would like to see the effects of inlining C/C++ functions at the source code level.
After some searchs it looks like IDEs like Eclipse can do that on Java code, but not in C/C++. Am I right?
Also I would like to control when to inline or not inline a function at the calling site. I understand that Intel's ICC "#pragma forceinline" is exactly addressing this, in contrast to the GCC "__attribute__((always_inline))" which is addressing all the function invocations.
I understand that it would be possible to implement such translation using clang. Do you foresee any major roadblock for that?
I am also wondering if anyone has done anything similar, or there exist other alternatives I haven't though of...
inline controlling is to some extend compiler-specific.
An alternative could be the use of macros that either hold a function call or the function code itself. This is not practical for big functions, but on the other hand big functions are usually not inlined.
Hope this helps...
You are right, but it requires some effort to recode functions as macros and macros are error prone because there is no control about parameters scope, name collision, etc.
I've found that the Scout tool (https://tu-dresden.de/zih/forschung/projekte/scout/) has implemented that with the following compiler directive
#pragma scout function expand
http://cppcheck.sourceforge.net/
I implemented myself a tool do this. Find the justification to start from scratch here
