re: Understanding the classical model for linking, groundwork: The algorithm
"selectany" symbols are necessary for:a) member functions defined in the class definition body, when inlining is disabled for debugging;b) vtable;c) identical non-inline template functions (and member...

@Matt:I'm not positive about this (there is conflicting information), but in C++, functions marked 'inline' still have external linkage. I didn't test, but from the MSDN docs it seems that MSVC is...

re: Understanding the classical model for linking, groundwork: The algorithm
One more comment on "inline" for the moment.C++03 standard, 7.1.2 [Function specifiers], footnote #79: "The 'inline' keyword has no effect on the linkage of a function". Para 4: "If a function with...

re: Understanding the classical model for linking, groundwork: The algorithm
Some linkage models also keep a list of required symbols per symbol rather than per OBJ. This leads to less spurious dependency growth. You can get this behavior in gcc by passing...

re: Understanding the classical model for linking, groundwork: The algorithm
I've used __declspec(selectany) many times when I needed a module-wide global var. Easier than having it once in a .h, and actually declared in a .c[pp] (or doing macro-trickery to achieve that). Just...

For the printf issue - printf OBJ should not include _fltused. Yes if the app uses %f and does not use floating point the app will crash, but any app that uses floating formats will itself include...

I think Anonymous123 found it. by knocking out the reference to _fltused in vfprintf's .OBJ (all other *printf call this one), the floating point library is not called in unless used elsewhere. This...

I don't get why you need __fltused. I thought that something like 1.2 + 3.4 gets compiled into something like __fltadd(1.2, 3.4). Then you can resolve __fltadd instead of a bogus symbol like __fltused.

To make a classical analogy: Wayne's World's effect on the popularity of Bohemian Rhapsody is similar to Pavarotti's effect on the popularity of "Nessun dorma" from Turandot.

To be fair, Bob, the "familiar" phrase is both times used to refer to the same cross-handed piano vamp. I think a better word would have been "iconic".Interestingly, as a 29 year old with a minor in...

There is bunch of float point conversion function pointers that are initialized by default to print-error-and-exit trap address.When _fltused is defined by the compiler in any obj file, float-point...
