How to describe 'naked' attribute function on IAR?

yasuhikokoumoto — Fri, 13 Feb 2015 21:47:36 GMT

Hello IAR EWARM experts,

I posted this issue to the ARM Connected Community but have not been received any responses.

Therefore I would like to post to this site.

I would like to know how to describe a naked attribute function.

The code was compiled successfully with a standalone GCC but IAR GCC could not and display the following error messages.

エラー[Pe079]: expected a type specifier D:\KL25 Sample Code\kl25_sc_rev10\klxx-sc-baremetal\src\projects\svc_demo\svc_demo.c 238

エラー[Pe141]: unnamed prototyped parameters not allowed when body is present D:\KL25 Sample Code\kl25_sc_rev10\klxx-sc-baremetal\src\projects\svc_demo\svc_demo.c 238

C/C++コンパイラ実行中のエラー

Can anyone help me?

Thank you and best regards,

Yasuhiko Koumoto.

Hi Yasuhiko

Try the non-standard extended keyword __stackless

Hi Mark,

thank you, the compilation was done successfully with __stackless.

However, the __stackless keyword was not accepted by the standalone GCC.

Is it IAR specific keyword?

Yasuhiko

These type of things are not standard and so are compiler specific.

You can use a define instead and declare the define according to the compiler used and then it is automated.
