inline in ATS

[Brandon Barker]

Is there a way or desire to have a function in ATS generate an inline C function declaration?

Something like the following could possibly act as both a hint and a way to export the function to C:

extern
fun myfun (...): int = "inline#myfun_in_c" 

Maybe most compilers are already good enough at spotting functions to be inlined that this isn't very helpful for function calls in loops.

I would just leave it to the compiler.

The important thing is to *facilitate* inlining. For instance, using templates
or putting code in a CATS-file can make sure that the functions to be inlined
stay in the same compilation unit where they are called.

I often combine all the files in a program into one (by using #include and
some other features of ATS) to allow the C compiler to "churn" it :)

The code in ATSLIB/prelude and ATSLIB/libats consists of mostly templates.
So most ATSLIB-functions get "churned" as well.

Would -fwhole-program also work?

(The #include et al approach should work as long as -funit-at-a-time
is active.)

I did not try -fwhole-program. I tried a flag of the name '-compile' (?); it worked but the flag
was moved from the recent versions of gcc.

There is another reason for me to use ATS to generate a single C file containing everything.

I could use TinyCC (TCC) to compile such a file. Due to the speed of TCC, it is a bit like using
the C code as some kind of script.

-fwhole-program seems to work, at least in a simple case, _if_ I avoid
dynload. So it is not as good a method.
