Other Parts Discussed in Thread: RM48L952

Hello all,

Just wondering if it is possible to inline C functions (and if yes how). The "inline" seems to be ignored, but perhaps I do it not the correct way.

I also tried to activate "inline functions called once" in the project options.

To check if a function is inlined I do:Debug project on target, view disassembly and check if there is a BL instruction.

Target: RM48L952, tested with compiler 5.0.1

Thank you and best Regards!

Roger,

Inlining is supported, but you have to compile with optimization as well as the inline keyword for inlining to happen.

There is also a list of things that prevent a function from being inlined.

Section 2.11 of the Compiler manual (2.5 pages) explaines what's needed to enable inlining and has the list of disqualifications.

Please check this section, and if you don't find what you need please give an example that's not working for you along with the compiler command line being used.

Thanks and Best Regards,

Anthony

Sorry Martin,

Not sure what's going on w. the links.

I have a bookmark on this page: http://processors.wiki.ti.com

That's the go-to place..

Under this heading Development Tools select the link:

Code Generation Tools Compiler, assembler, linker and associated tools.

On the Code Generation tools page, select

Compiler Manuals

On the compiler manuals page, you can see the latest manuals.

For the Hercules products the relevant manuals are:

ARM C/C++ Optimizing Compiler User's Guide
ARM Assembly Language Tools User's Guide << This is the manual that has the linker info in it for the above answer.

p.s. the above are not intended to be functional links, but the path to navigate from the top level processors.wiki.ti.com page....

Thank you Anthony for pointing me to the correct document.

Inlining works in my project now as documented.

Best Regards,

Roger
