I recently noticed
pragma(inline, true)
which looks extremely useful. A couple of questions :
1. Is this cross-compiler compatible?
2. Can I declare a function in one module and have it _inlined_
in another module at the call site?
I’m looking to write functions that expand to approx one or
even zero machine instructions and having the overhead of a
function call would be disastrous; in some cases would make it
pointless having the function due to the slowdown.
pragma inline will work for dmd.
and it used to fail if it couldn't inline.
Now it just generates a warning.
So with -w it will still fail.
Afaik other compilers cannot warn if the in-lining fails but I
might be wrong.
And ldc/gdc should be able to inline most code which makes sense
to inline.
