[Tinycc-devel] Re : How exactly inline works and should I inline all the time?

[david . koch]

Inline is used very specifically where the code has to be fast.

Best is only to inline tiny parts of code that will be "inlined".

That's to say "injected" into the source code where it is needed.

Otherwise it is a full jump to a distant function, with context saving.

Hence the "inlining" only serves a very specific purpose.

Regards.

Objet: [Tinycc-devel] How exactly inline works and should I inline all the time?

Hi!

I don't know if we must only post questions that are specific to the TCC 
compiler
specifically (even tho this question can differ from compiler to compiler) or 
we can
make questions about C in general and in the case that the first is true then 
please
inform me so I know. Anyway I wanted to ask how inline works specifically and 
not
generally. I know generally that it "puts the source code" inline so we don't 
have to use
"jmp" but is there anything else to it that I should know? Are there any 
dangers or reasons
than someone should not use it? Also is there a way to tell the compiler to 
inline every
function rather than always having to add the "inline" keyword?
