Hi!

Is there any restriction on function which could be inlined?

I would like to inline some routine into kernel body. I add "-Minline=foo" option to compiler, but it says

Hi Alexey,

Inlining is a big topic so I'll first point you to Chapter 4 of the PGI Compiler User's Guide. It does have a section on inlining restrictions.

Note "-Minfo=inline" might give you details on why a routine was not inlined. Though, this only is printed if the compiler attempted to inline the function but failed.

Also, if "foo" is not in the same source file, you will need to first create an inline library using the "-Mextract" flag (see docs for details).

Hope this helps,
Mat

Hi Mat!

It's help, but I still have some questions.
PGI reports that reshaping is not allowed.... but I doesn't reshape arrays

Is "kts" a variable? That would cause a reshape since the compiler can't tell the actual and dummy argument's lower bounds are the same.

You can try adding the flag "-Minline=reshape" to get the compiler to inline this routine.
